Where reasonable, each program attempts to emulate the MS-DOS equivalent command. However, unnecessary restrictions and oddities of DOS are not emulated. For instance, it is possible to move subdirectories from one subdirectory to another. Mtools is sufficient to give access to MS-DOS file systems. For instance, commands such as @code{mdir a:} work on the @code{a:} floppy without any preliminary mounting or initialization (assuming the default @file{@value{SYSCONFDIR}mtools.conf} works on your machine). With mtools, one can change floppies too without unmounting and mounting. @insertcopying @menu * Location:: Where to find mtools and early bug fixes * Common features:: Common features of all mtools commands * Configuration:: How to configure mtools for your environment * Commands:: The available mtools commands * Compiling mtools:: Architecture specific compilation flags * Porting mtools:: Porting mtools to architectures which are not yet supported * Command Index:: Command Index * Variable Index:: Variable Index * Concept Index:: Concept Index @end menu @node Location, Common features, Top, Top @chapter Where to get mtools @cindex bugs @cindex ALPHA patches @cindex patches @cindex diffs @cindex mailing list Mtools can be found at the following places (and their mirrors): @example http://ftp.gnu.org/gnu/mtools/mtools-@value{VERSION}.tar.gz http://mtools.linux.lu/mtools-@value{VERSION}.tar.gz ftp://www.tux.org/pub/knaff/mtools/mtools-@value{VERSION}.tar.gz ftp://ibiblio.unc.edu/pub/Linux/utils/disk-management/mtools-@value{VERSION}.tar.gz @end example Before reporting a bug, make sure that it has not yet been fixed in the Alpha patches which can be found at: @example http://ftp.gnu.org/gnu/mtools/ http://mtools.linux.lu/ ftp://www.tux.org/pub/knaff/mtools @end example These patches are named @code{mtools-}@var{version}@code{-}@var{ddmm}@code{.taz}, where version stands for the base version, @var{dd} for the day and @var{mm} for the month.

Only the filename part is mandatory, the drive letter and the subdirectory are optional. Filenames without a drive letter refer to Unix files. Subdirectory names can use either the '@code{/}' or '@code{\}' separator. The use of the '@code{\}' separator or wildcards requires the names to be enclosed in quotes to protect them from the shell. However, wildcards in Unix filenames should not be enclosed in quotes, because here we @strong{want} the shell to expand them. The regular expression "pattern matching" routines follow the Unix-style rules. For example, `@code{*}' matches all MS-DOS files in lieu of `@code{*.*}'. The archive, hidden, read-only and system attribute bits are ignored during pattern matching. All options use the @code{-} (minus) as their first character, not @code{/} as you'd expect in MS-DOS. Most mtools commands allow multiple filename parameters, which doesn't follow MS-DOS conventions, but which is more user-friendly. Most mtools commands allow options that instruct them how to handle file name clashes. @xref{name clashes}, for more details on these. All commands accept the @code{-V} flags which prints the version, and most accept the @code{-v} flag, which switches on verbose mode. In verbose mode, these commands print out the name of the MS-DOS files upon which they act, unless stated otherwise. @xref{Commands}, for a description of the options which are specific to each command. @node drive letters, directory, arguments, Common features @section Drive letters The meaning of the drive letters depends on the target architectures. However, on most target architectures, drive A is the first floppy drive, drive B is the second floppy drive (if available), drive J is a Jaz drive (if available), and drive Z is a Zip drive (if available). On those systems where the device name is derived from the SCSI id, the Jaz drive is assumed to be at SCSI target 4, and the Zip at SCSI target 5 (factory default settings). On Linux, both drives are assumed to be the second drive on the SCSI bus (/dev/sdb). The default settings can be changes using a configuration file (@pxref{Configuration}). The drive letter : (colon) has a special meaning. It is used to access image files which are directly specified on the command line using the @code{-i} options. Example: @example mcopy -i my-image-file.bin ::file1 ::file2 . @end example This copies @code{file1} and @code{file2} from the image file (@code{my-image-file.bin}) to the @code{/tmp} directory. You can also supply an offset within the image file by including @code{@@@@}@var{offset} into the file name. Example: @example mcopy -i my-image-file.bin@@@@1M ::file1 ::file2 . @end example This looks for the image at the offset of 1M in the file, rather than at its beginning. @node directory, long names, drive letters, Common features @section Current working directory @pindex mcd (introduction) @cindex Directory @cindex Working directory @cindex Current working directory @cindex Default directory The @code{mcd} command (@ref{mcd}) is used to establish the device and the current working directory (relative to the MS-DOS file system), otherwise the default is assumed to be @code{A:/}. However, unlike MS-DOS, there is only one working directory for all drives, and not one per drive. @node long names, name clashes, directory, Common features @section VFAT-style long file names @cindex Long file name @cindex Windows 95-style file names @cindex VFAT-style file names @cindex Primary file name (long names) @cindex Secondary file name (long names) This version of mtools supports VFAT style long filenames. If a Unix filename is too long to fit in a short DOS name, it is stored as a VFAT long name, and a companion short name is generated. This short name is what you see when you examine the disk with a pre-7.0 version of DOS. The following table shows some examples of short names: @example Long name MS-DOS name Reason for the change --------- ---------- --------------------- thisisatest THISIS~1 filename too long alain.knaff ALAIN~1.KNA extension too long prn.txt PRN~1.TXT PRN is a device name .abc ABC~1 null filename hot+cold HOT_CO~1 illegal character @end example As you see, the following transformations happen to derive a short name: @itemize @bullet @item Illegal characters are replaced by underscores. The illegal characters are @code{;+=[]',\"*\\<>/?:|}. @item Extra dots, which cannot be interpreted as a main name/extension separator are removed @item A @code{~}@var{n} number is generated, @item The name is shortened so as to fit in the 8+3 limitation @end itemize The initial Unix-style file name (whether long or short) is also called the @dfn{primary} name, and the derived short name is also called the @dfn{secondary} name. Example: @example mcopy /etc/motd a:Reallylongname @end example Mtools creates a VFAT entry for Reallylongname, and uses REALLYLO as a short name. Reallylongname is the primary name, and REALLYLO is the secondary name. @example mcopy /etc/motd a:motd @end example Motd fits into the DOS filename limits. Mtools doesn't need to derivate another name. Motd is the primary name, and there is no secondary name. In a nutshell: The primary name is the long name, if one exists, or the short name if there is no long name. Although VFAT is much more flexible than FAT, there are still names that are not acceptable, even in VFAT. There are still some illegal characters left (@code{\"*\\<>/?:|}), and device names are still reserved. @example Unix name Long name Reason for the change --------- ---------- --------------------- prn prn-1 PRN is a device name ab:c ab_c-1 illegal character @end example As you see, the following transformations happen if a long name is illegal: @itemize @bullet @item Illegal characters are replaces by underscores, @item A @code{-}@var{n} number is generated, @end itemize @node name clashes, case sensitivity, long names, Common features @section Name clashes @cindex Name clashes @cindex Duplicate file names @cindex Overwriting files @cindex Primary file name (name clashes) @cindex Secondary file name (name clashes) When writing a file to disk, its long name or short name may collide with an already existing file or directory. This may happen for all commands which create new directory entries, such as @code{mcopy}, @code{mmd}, @code{mren}, @code{mmove}. When a name clash happens, mtools asks you what it should do. It offers several choices: @table @code @item overwrite Overwrites the existing file. It is not possible to overwrite a directory with a file. @item rename Renames the newly created file. Mtools prompts for the new filename @item autorename Renames the newly created file. Mtools chooses a name by itself, without prompting @item skip Gives up on this file, and moves on to the next (if any) @end table To chose one of these actions, type its first letter at the prompt. If you use a lower case letter, the action only applies for this file only, if you use an upper case letter, the action applies to all files, and you won't be prompted again. You may also chose actions (for all files) on the command line, when invoking mtools: @table @code @item -D o Overwrites primary names by default. @item -D O Overwrites secondary names by default. @item -D r Renames primary name by default. @item -D R Renames secondary name by default. @item -D a Autorenames primary name by default. @item -D A Autorenames secondary name by default. @item -D s Skip primary name by default. @item -D S Skip secondary name by default. @item -D m Ask user what to do with primary name. @item -D M Ask user what to do with secondary name. @end table Note that for command line switches lower/upper differentiates between primary/secondary name whereas for interactive choices, lower/upper differentiates between just-this-time/always. The primary name is the name as displayed in Windows 95 or Windows NT: i.e. the long name if it exists, and the short name otherwise. The secondary name is the "hidden" name, i.e. the short name if a long name exists. By default, the user is prompted if the primary name clashes, and the secondary name is autorenamed. If a name clash occurs in a Unix directory, mtools only asks whether to overwrite the file, or to skip it. @node case sensitivity, high capacity formats, name clashes, Common features @section Case sensitivity of the VFAT file system @cindex Case sensitivity The VFAT file system is able to remember the case of the filenames. However, filenames which differ only in case are not allowed to coexist in the same directory. For example if you store a file called LongFileName on a VFAT file system, mdir shows this file as LongFileName, and not as Longfilename. However, if you then try to add LongFilename to the same directory, it is refused, because case is ignored for clash checks. The VFAT file system allows to store the case of a filename in the attribute byte, if all letters of the filename are the same case, and if all letters of the extension are the same case too. Mtools uses this information when displaying the files, and also to generate the Unix filename when mcopying to a Unix directory. This may have unexpected results when applied to files written using an pre-7.0 version of DOS: Indeed, the old style filenames map to all upper case. This is different from the behavior of the old version of mtools which used to generate lower case Unix filenames. @node high capacity formats, exit codes, case sensitivity, Common features @section high capacity formats @cindex Special formats @cindex High capacity formats @cindex Odd formats @cindex Weird formats @cindex Formats, high capacity @cindex Linux enhancements (High Capacity Formats) Mtools supports a number of formats which allow to store more data on disk as usual. Due to different operating system abilities, these formats are not supported on all operating systems. Mtools recognizes these formats transparently where supported. In order to format these disks, you need to use an operating system specific tool. For Linux, suitable floppy tools can be found in the @code{fdutils} package at the following locations~: @example @code{ftp://www.tux.org/pub/knaff/fdutils/}. @code{ftp://ibiblio.unc.edu/pub/Linux/utils/disk-management/fdutils-*} @end example See the manual pages included in that package for further detail: Use @code{superformat} to format all formats except XDF, and use @code{xdfcopy} to format XDF. @menu * more sectors:: Putting more sectors per track on the disk * bigger sectors:: Use bigger sectors to save header space * 2m:: Use a standard first track * XDF:: OS/2's eXtended density format @end menu @node more sectors, bigger sectors, high capacity formats, high capacity formats @subsection More sectors @cindex fdformat @cindex vgacopy @cindex DMF disks @cindex Windows 95 (DMF disks) The oldest method of fitting more data on a disk is to use more sectors and more cylinders. Although the standard format uses 80 cylinders and 18 sectors (on a 3 1/2 high density disk), it is possible to use up to 83 cylinders (on most drives) and up to 21 sectors. This method allows to store up to 1743K on a 3 1/2 HD disk. However, 21 sector disks are twice as slow as the standard 18 sector disks because the sectors are packed so close together that we need to interleave them. This problem doesn't exist for 20 sector formats. These formats are supported by numerous DOS shareware utilities such as @code{fdformat} and @code{vgacopy}. In his infinite hubris, Bill Gate$ believed that he invented this, and called it @samp{DMF disks}, or @samp{Windows formatted disks}. But in reality, it has already existed years before! Mtools supports these formats on Linux, on SunOS and on the DELL Unix PC. @node bigger sectors, 2m, more sectors, high capacity formats @subsection Bigger sectors @cindex bigger sectors By using bigger sectors it is possible to go beyond the capacity which can be obtained by the standard 512-byte sectors. This is because of the sector header. The sector header has the same size, regardless of how many data bytes are in the sector. Thus, we save some space by using @emph{fewer}, but bigger sectors. For example, 1 sector of 4K only takes up header space once, whereas 8 sectors of 512 bytes have also 8 headers, for the same amount of useful data. This method allows to store up to 1992K on a 3 1/2 HD disk. Mtools supports these formats only on Linux. @node 2m, XDF, bigger sectors, high capacity formats @subsection 2m @cindex 2m The 2m format was originally invented by Ciriaco Garcia de Celis. It also uses bigger sectors than usual in order to fit more data on the disk. However, it uses the standard format (18 sectors of 512 bytes each) on the first cylinder, in order to make these disks easier to handle by DOS. Indeed this method allows to have a standard sized boot sector, which contains a description of how the rest of the disk should be read. However, the drawback of this is that the first cylinder can hold less data than the others. Unfortunately, DOS can only handle disks where each track contains the same amount of data. Thus 2m hides the fact that the first track contains less data by using a @dfn{shadow FAT}. (Usually, DOS stores the FAT in two identical copies, for additional safety. XDF stores only one copy, but tells DOS that it stores two. Thus the space that would be taken up by the second FAT copy is saved.) This also means that you should @strong{never use a 2m disk to store anything else than a DOS file system}. Mtools supports these formats only on Linux. @node XDF, , 2m, high capacity formats @subsection XDF @cindex XDF disks @cindex OS/2 (XDF disks) XDF is a high capacity format used by OS/2. It can hold 1840 K per disk. That's lower than the best 2m formats, but its main advantage is that it is fast: 600 milliseconds per track. That's faster than the 21 sector format, and almost as fast as the standard 18 sector format. In order to access these disks, make sure mtools has been compiled with XDF support, and set the @code{use_xdf} variable for the drive in the configuration file. @xref{Compiling mtools}, and @ref{miscellaneous variables}, for details on how to do this. Fast XDF access is only available for Linux kernels which are more recent than 1.1.34. Mtools supports this format only on Linux. @strong{Caution / Attention distributors}: If mtools is compiled on a Linux kernel more recent than 1.3.34, it won't run on an older kernel. However, if it has been compiled on an older kernel, it still runs on a newer kernel, except that XDF access is slower. It is recommended that distribution authors only include mtools binaries compiled on kernels older than 1.3.34 until 2.0 comes out. When 2.0 will be out, mtools binaries compiled on newer kernels may (and should) be distributed. Mtools binaries compiled on kernels older than 1.3.34 won't run on any 2.1 kernel or later. @node exit codes, bugs, high capacity formats, Common features @section Exit codes All the Mtools commands return 0 on success, 1 on utter failure, or 2 on partial failure. All the Mtools commands perform a few sanity checks before going ahead, to make sure that the disk is indeed an MS-DOS disk (as opposed to, say an ext2 or MINIX disk). These checks may reject partially corrupted disks, which might otherwise still be readable. To avoid these checks, set the MTOOLS_SKIP_CHECK environmental variable or the corresponding configuration file variable (@pxref{global variables}) @node bugs, , exit codes, Common features @section Bugs An unfortunate side effect of not guessing the proper device (when multiple disk capacities are supported) is an occasional error message from the device driver. These can be safely ignored. The fat checking code chokes on 1.72 Mb disks mformatted with pre-2.0.7 mtools. Set the environmental variable MTOOLS_FAT_COMPATIBILITY (or the corresponding configuration file variable, @ref{global variables}) to bypass the fat checking. @comment MANskip 1 @ignore @unnumbered Name mtools.conf - mtools configuration files @comment MANend-skip 5 @section Description This manual page describes the configuration files for mtools.

The configuration files @comment MANend-skip 5 are called @file{@value{SYSCONFDIR}mtools.conf} and @file{~/.mtoolsrc}. If the environmental variable @code{MTOOLSRC} is set, its contents is used as the filename for a third configuration file. These configuration files describe the following items: @itemize @bullet @item Global configuration flags and variables @item Per drive flags and variables @end itemize @menu * configuration file location:: Where mtools looks for its configuration files * general syntax:: The layout of the configuration files * default values:: Why you don't need a configuration file in most cases * global variables:: Variables that are independent of the drive * per drive variables:: Variables that are specific to a given drive * parsing order:: Location of configuration files and parsing order * old style configuration:: Backwards compatibility @end menu @node configuration file location, general syntax, Configuration, Configuration @section Location of the configuration files @cindex Configuration file name @cindex Name of configuration files @cindex Location of configuration files @file{@value{SYSCONFDIR}mtools.conf} is the system-wide configuration file, and @file{~/.mtoolsrc} is the user's private configuration file. On some systems, the system-wide configuration file is called @file{/etc/default/mtools.conf} instead. @node general syntax, default values, configuration file location, Configuration @subsection General configuration file syntax @cindex Syntax of the configuration file @cindex Configuration file syntax The configuration files is made up of sections. Each section starts with a keyword identifying the section followed by a colon. Then follow variable assignments and flags. Variable assignments take the following form: @display name=value @end display Flags are lone keywords without an equal sign and value following them. A section either ends at the end of the file or where the next section begins. Lines starting with a hash (@code{#}) are comments. Newline characters are equivalent to whitespace (except where ending a comment). The configuration file is case insensitive, except for item enclosed in quotes (such as filenames). @node default values, global variables, general syntax, Configuration @section Default values @cindex Default values @cindex Default configuration @cindex Configuration file For most platforms, mtools contains reasonable compiled-in defaults for physical floppy drives. Thus, you usually don't need to bother with the configuration file, if all you want to do with mtools is to access your floppy drives. On the other hand, the configuration file is needed if you also want to use mtools to access your hard disk partitions and DOSEMU image files. @node global variables, per drive variables, default values, Configuration @section Global variables @cindex Global configuration variables @cindex Drive independent configuration variables @cindex Environmental variables @vindex MTOOLS_SKIP_CHECK @vindex MTOOLS_FAT_COMPATIBILITY @vindex MTOOLS_LOWER_CASE @vindex MTOOLS_NO_VFAT @vindex MTOOLS_DOTTED_DIR @vindex MTOOLS_NAME_NUMERIC_TAIL @vindex MTOOLS_TWENTY_FOUR_HOUR_CLOCK @vindex MTOOLS_LOCK_TIMEOUT @cindex FreeDOS Global flags may be set to 1 or to 0. The following global flags are recognized: @table @code @item MTOOLS_SKIP_CHECK If this is set to 1, mtools skips most of its sanity checks. This is needed to read some Atari disks which have been made with the earlier ROMs, and which would not be recognized otherwise. @item MTOOLS_FAT_COMPATIBILITY If this is set to 1, mtools skips the fat size checks. Some disks have a bigger FAT than they really need to. These are rejected if this option is not set. @item MTOOLS_LOWER_CASE If this is set to 1, mtools displays all-upper-case short filenames as lowercase. This has been done to allow a behavior which is consistent with older versions of mtools which didn't know about the case bits. @item MTOOLS_NO_VFAT If this is set to 1, mtools won't generate VFAT entries for filenames which are mixed-case, but otherwise legal dos filenames. This is useful when working with DOS versions which can't grok VFAT long names, such as FreeDOS. @item MTOOLS_DOTTED_DIR In a wide directory, prints the short name with a dot instead of spaces separating the basename and the extension. @item MTOOLS_NAME_NUMERIC_TAIL If this is set to one (default), generate numeric tails for all long names (~1). If set to zero, only generate numeric tails if otherwise a clash would have happened. @item MTOOLS_TWENTY_FOUR_HOUR_CLOCK If 1, uses the European notation for times (twenty four hour clock), else uses the UK/US notation (am/pm) @item MTOOLS_LOCK_TIMEOUT How long, in seconds, to wait for a locked device to become free. Defaults to 30. @end table Example: Inserting the following line into your configuration file instructs mtools to skip the sanity checks: @example MTOOLS_SKIP_CHECK=1 @end example Global variables may also be set via the environment: @example export MTOOLS_SKIP_CHECK=1 @end example Global string variables may be set to any value: @table @code @item MTOOLS_DATE_STRING The format used for printing dates of files.

Only primary partitions are accessible using this method, and they are numbered from 1 to 4. For logical partitions, use the more general @code{offset} variable. The @code{partition} variable is intended for removable media such as Syquest disks, ZIP drives, and magneto-optical disks. Although traditional DOS sees Syquest disks and magneto-optical disks as @samp{giant floppy disks} which are unpartitioned, OS/2 and Windows NT treat them like hard disks, i.e. partitioned devices. The @code{partition} flag is also useful DOSEMU hdimages. It is not recommended for hard disks for which direct access to partitions is available through mounting. @item offset @cindex Ram disk @cindex Atari Ram disk Describes where in the file the MS-DOS file system starts. This is useful for logical partitions in DOSEMU hdimages, and for ATARI ram disks. By default, this is zero, meaning that the file system starts right at the beginning of the device or file. @end table @node geometry description, open flags, location information, per drive variables @subsection Disk Geometry Configuration @cindex Disk Geometry @cindex Configuration of disk geometry @cindex Description of disk geometry @cindex Format of disk @cindex High density disk @cindex Low density disk @pindex mformat (geometry used for) Geometry information describes the physical characteristics about the disk. Its has three purposes: @table @asis @item formatting The geometry information is written into the boot sector of the newly made disk. However, you may also describe the geometry information on the command line. @xref{mformat}, for details. @item filtering On some Unixes there are device nodes which only support one physical geometry. For instance, you might need a different node to access a disk as high density or as low density. The geometry is compared to the actual geometry stored on the boot sector to make sure that this device node is able to correctly read the disk. If the geometry doesn't match, this drive entry fails, and the next drive entry bearing the same drive letter is tried. @xref{multiple descriptions}, for more details on supplying several descriptions for one drive letter. If no geometry information is supplied in the configuration file, all disks are accepted. On Linux (and on SPARC) there exist device nodes with configurable geometry (@file{/dev/fd0}, @file{/dev/fd1} etc), and thus filtering is not needed (and ignored) for disk drives. (Mtools still does do filtering on plain files (disk images) in Linux: this is mainly intended for test purposes, as I don't have access to a Unix which would actually need filtering). If you do not need filtering, but want still a default geometry for mformatting, you may switch off filtering using the @code{mformat_only} flag. If you want filtering, you should supply the @code{filter} flag. If you supply a geometry, you must supply one of both flags. @item initial geometry On devices that support it (usually floppy devices), the geometry information is also used to set the initial geometry. This initial geometry is applied while reading the boot sector, which contains the real geometry. If no geometry information is supplied in the configuration file, or if the @code{mformat_only} flag is supplied, no initial configuration is done. On Linux, initial geometry is not really needed, as the configurable devices are able to auto-detect the disk type accurately enough (for most common formats) to read the boot sector. @end table Wrong geometry information may lead to very bizarre errors. That's why I strongly recommend that you add the @code{mformat_only} flag to your drive description, unless you really need filtering or initial geometry. The following geometry related variables are available: @table @code @item cylinders @itemx tracks @vindex cylinders @vindex tracks The number of cylinders. (@code{cylinders} is the preferred form, @code{tracks} is considered obsolete) @item heads @vindex heads The number of heads (sides). @item sectors @vindex sectors The number of sectors per track. @end table Example: the following drive section describes a 1.44M drive: @example drive a: file="/dev/fd0H1440" fat_bits=12 cylinders=80 heads=2 sectors=18 mformat_only @end example The following shorthand geometry descriptions are available: @table @code @item 1.44m high density 3 1/2 disk. Equivalent to: @code{fat_bits=12 cylinders=80 heads=2 sectors=18} @item 1.2m high density 5 1/4 disk. Equivalent to: @code{fat_bits=12 cylinders=80 heads=2 sectors=15} @item 720k double density 3 1/2 disk. Equivalent to: @code{fat_bits=12 cylinders=80 heads=2 sectors=9} @item 360k double density 5 1/4 disk. Equivalent to: @code{fat_bits=12 cylinders=40 heads=2 sectors=9} @end table The shorthand format descriptions may be amended. For example, @code{360k sectors=8} describes a 320k disk and is equivalent to: @code{fat_bits=12 cylinders=40 heads=2 sectors=8} @node open flags, miscellaneous variables, geometry description, per drive variables @subsection Open Flags @vindex sync @vindex nodelay @vindex exclusive @cindex open flags @cindex synchronous writing @cindex exclusive access to a drive Moreover, the following flags are available: @table @code @item sync All i/o operations are done synchronously @item nodelay The device or file is opened with the O_NDELAY flag. This is needed on some non-Linux architectures. @item exclusive The device or file is opened with the O_EXCL flag. On Linux, this ensures exclusive access to the floppy drive. On most other architectures, and for plain files it has no effect at all. @end table @node miscellaneous variables, miscellaneous flags, open flags, per drive variables @subsection General Purpose Drive Variables The following general purpose drive variables are available. Depending to their type, these variables can be set to a string (precmd) or an integer (all others) @table @code @item fat_bits @vindex fat_bits The number of FAT bits. This may be 12 or 16. This is very rarely needed, as it can almost always be deduced from information in the boot sector. On the contrary, describing the number of fat bits may actually be harmful if you get it wrong. You should only use it if mtools gets the auto-detected number of fat bits wrong, or if you want to mformat a disk with a weird number of fat bits. @item codepage Describes the DOS code page used for short filenames. This is a number between 1 and 999. By default, code page 850 is used. The reason for this is because this code page contains most of the characters that are also available in ISO-Latin-1. You may also specify a global code page for all drives by using the global @code{default_codepage} parameter (outside of any drive description). This parameters exists starting at version 4.0.0 @item precmd @cindex Solaris (volcheck) @cindex Executing commands before opening the device On some variants of Solaris, it is necessary to call 'volcheck -v' before opening a floppy device, in order for the system to notice that there is indeed a disk in the drive. @code{precmd="volcheck -v"} in the drive clause establishes the desired behavior. @item blocksize @cindex raw device @cindex character devices @cindex blocksize This parameter represents a default block size to be always used on this device. All I/O is done with multiples of this block size, independently of the sector size registered in the file system's boot sector. This is useful for character devices whose sector size is not 512, such as for example CD-ROM drives on Solaris. @end table Only the @code{file} variable is mandatory. The other parameters may be left out. In that case a default value or an auto-detected value is used. @node miscellaneous flags, multiple descriptions, miscellaneous variables, per drive variables @subsection General Purpose Drive Flags A flag can either be set to 1 (enabled) or 0 (disabled). If the value is omitted, it is enabled. For example, @code{scsi} is equivalent to @code{scsi=1} @table @code @item nolock @cindex disable locking @cindex locking (disabling it) @cindex plain floppy: device xxx busy Instruct mtools to not use locking on this drive. This is needed on systems with buggy locking semantics. However, enabling this makes operation less safe in cases where several users may access the same drive at the same time. @item scsi @cindex setuid installation (needed for raw SCSI I/O) @cindex Solaris (Raw access to SCSI devices such as Zip & Jaz) @cindex SunOS (Raw access to SCSI devices such as Zip & Jaz) @cindex Zip disks (raw SCSI access) @cindex Jaz disks (raw SCSI access) @cindex Syquest disks (raw SCSI access) @cindex SCSI devices When set to 1, this option tells mtools to use raw SCSI I/O instead of the standard read/write calls to access the device. Currently, this is supported on HP-UX, Solaris and SunOS. This is needed because on some architectures, such as SunOS or Solaris, PC media can't be accessed using the @code{read} and @code{write} system calls, because the OS expects them to contain a Sun specific "disk label". As raw SCSI access always uses the whole device, you need to specify the "partition" flag in addition On some architectures, such as Solaris, mtools needs root privileges to be able to use the @code{scsi} option. Thus mtools should be installed setuid root on Solaris if you want to access Zip/Jaz drives. Thus, if the @code{scsi} flag is given, @code{privileged} is automatically implied, unless explicitly disabled by @code{privileged=0} Mtools uses its root privileges to open the device, and to issue the actual SCSI I/O calls. Moreover, root privileges are only used for drives described in a system-wide configuration file such as @file{@value{SYSCONFDIR}mtools.conf}, and not for those described in @file{~/.mtoolsrc} or @file{$MTOOLSRC}. @item privileged @cindex setuid installation @cindex setgid installation When set to 1, this instructs mtools to use its setuid and setgid privileges for opening the given drive. This option is only valid for drives described in the system-wide configuration files (such as @file{@value{SYSCONFDIR}mtools.conf}, not @file{~/.mtoolsrc} or @file{$MTOOLSRC}). Obviously, this option is also a no op if mtools is not installed setuid or setgid. This option is implied by 'scsi=1', but again only for drives defined in system-wide configuration files. Privileged may also be set explicitly to 0, in order to tell mtools not to use its privileges for a given drive even if @code{scsi=1} is set. Mtools only needs to be installed setuid if you use the @code{privileged} or @code{scsi} drive variables. If you do not use these options, mtools works perfectly well even when not installed setuid root. @item vold @cindex Solaris (vold) @cindex Vold (mediamgr) Instructs mtools to interpret the device name as a vold identifier rather than as a filename. The vold identifier is translated into a real filename using the @code{media_findname()} and @code{media_oldaliases()} functions of the @code{volmgt} library. This flag is only available if you configured mtools with the @code{--enable-new-vold} option before compilation. @item swap @cindex Atari @cindex Wordswapped Consider the media as a word-swapped Atari disk. @item use_xdf @cindex XDF disks (how to configure) @vindex use_xdf If this is set to a non-zero value, mtools also tries to access this disk as an XDF disk. XDF is a high capacity format used by OS/2. This is off by default. @xref{XDF}, for more details. @item mformat_only @vindex mformat_only Tells mtools to use the geometry for this drive only for mformatting and not for filtering. @item filter @vindex filter Tells mtools to use the geometry for this drive both for mformatting and filtering. @item remote Tells mtools to connect to floppyd (@pxref{floppyd}). @end table @node multiple descriptions, , miscellaneous flags, per drive variables @subsection Supplying multiple descriptions for a drive It is possible to supply multiple descriptions for a drive. In that case, the descriptions are tried in order until one is found that fits. Descriptions may fail for several reasons: @enumerate @item because the geometry is not appropriate, @item because there is no disk in the drive, @item or because of other problems. @end enumerate Multiple definitions are useful when using physical devices which are only able to support one single disk geometry. Example: @example drive a: file="/dev/fd0H1440" 1.44m drive a: file="/dev/fd0H720" 720k @end example This instructs mtools to use /dev/fd0H1440 for 1.44m (high density) disks and /dev/fd0H720 for 720k (double density) disks. On Linux, this feature is not really needed, as the /dev/fd0 device is able to handle any geometry. You may also use multiple drive descriptions to access both of your physical drives through one drive letter: @example drive z: file="/dev/fd0" drive z: file="/dev/fd1" @end example With this description, @code{mdir z:} accesses your first physical drive if it contains a disk. If the first drive doesn't contain a disk, mtools checks the second drive. When using multiple configuration files, drive descriptions in the files parsed last override descriptions for the same drive in earlier files. In order to avoid this, use the @code{drive+} or @code{+drive} keywords instead of @code{drive}. The first adds a description to the end of the list (i.e. it will be tried last), and the first adds it to the start of the list. @node parsing order, old style configuration, per drive variables, Configuration @section Location of configuration files and parsing order @cindex Parsing order @cindex Configuration file parsing order @cindex Configuration file name (parsing order) @cindex Name of configuration files (parsing order) @cindex Location of configuration files (parsing order) The configuration files are parsed in the following order: @enumerate @item compiled-in defaults @item @file{@value{SYSCONFDIR}mtools.conf} @item @file{~/.mtoolsrc}. @item @file{$MTOOLSRC} (file pointed by the @code{MTOOLSRC} environmental variable) @end enumerate Options described in the later files override those described in the earlier files. Drives defined in earlier files persist if they are not overridden in the later files. For instance, drives A and B may be defined in @file{@value{SYSCONFDIR}mtools.conf} and drives C and D may be defined in @file{~/.mtoolsrc} However, if @file{~/.mtoolsrc} also defines drive A, this new description would override the description of drive A in @file{@value{SYSCONFDIR}mtools.conf} instead of adding to it. If you want to add a new description to a drive already described in an earlier file, you need to use either the @code{+drive} or @code{drive+} keyword. @node old style configuration, , parsing order, Configuration @section Backwards compatibility with old configuration file syntax @cindex Backwards compatibility @cindex Old configuration file syntax @cindex Configuration file, old syntax The syntax described herein is new for version @code{mtools-3.0}. The old line-oriented syntax is still supported. Each line beginning with a single letter is considered to be a drive description using the old syntax. Old style and new style drive sections may be mixed within the same configuration file, in order to make upgrading easier. Support for the old syntax will be phased out eventually, and in order to discourage its use, I purposefully omit its description here. @comment MANskip 5 @node Commands, Compiling mtools, Configuration, Top @chapter Command list @cindex Command list @cindex List of available commands This section describes the available mtools commands, and the command line parameters that each of them accepts.

It has the following syntax: @code{floppyd} [@code{-d}] [@code{-l}] [@code{-s} @var{port}] [@code{-r} @var{user}] [@code{-b} @var{ipaddr}] [@code{-x} @var{display}] @var{devicenames} @code{floppyd} is always associated with an X server. It runs on the same machine as its X server, and listens on port 5703 and above. @subsection Authentication @code{floppyd} authenticates remote clients using the @code{Xauthority} protocol. Xhost authentication is not supported. Each floppyd is associated with an X server. When a remote client attempts to connect to floppyd, it sends floppyd the X authority record corresponding to floppyd's X server. Floppyd in turn then tries to open up a connection to the X server in order to verify the authenticity of the xauth record. If the connection to the X server succeeds, the client is granted access. @code{DISPLAY}. @strong{Caution}: In order to make authentication work correctly, the local host should @strong{not} be listed in the @code{xhost} list of allowed hosts. Indeed, hosts listed in @code{xhost} do not need a correct @code{Xauthority} cookie to connect to the X server. As @code{floppyd} runs on the same host as the X server, all its probe connection would succeed even for clients who supplied a bad cookie. This means that your floppy drive would be open to the world, i.e. a huge security hole. If your X server does not allow you to remove @code{localhost:0} and @code{:0} from the @code{xhost} list, you can prevent floppyd from probing those display names with the @code{-l} option. @subsection Command line options @table @code @item d Daemon mode. Floppyd runs its own server loop. Do not supply this if you start floppyd from @code{inetd.conf} @item s @var{port} Port number for daemon mode. Default is 5703 + @var{displaynumber}. This flag implies daemon mode. For example, for display @code{hitchhiker:5}, the port would be 5708. @item b @var{ipaddr} Bind address (for multi homed hosts). This flag implies daemon mode @item r @var{user} Run the server under as the given user @item x @var{display} X display to use for authentication. By default, this is taken from the @code{DISPLAY} variable. If neither the @code{x} attribute is present nor @code{DISPLAY} is set, floppyd uses @code{:0.0}. @end table @var{devicenames} is a list of device nodes to be opened. Default is @code{/dev/fd0}. Multiple devices are only supported on mtools versions newer than 3.9.11. @subsection Connecting to floppyd In order to use floppyd, add the flag @code{remote} to the device description in your @file{~/.mtoolsrc} file. If the flag @code{remote} is given, the @code{file} parameter of the device description is taken to be a remote address. It's format is the following: @var{hostname}@code{:}@var{displaynumber}[@code{/}[@var{baseport}][@code{/}@var{drive}]]. When using this entry, mtools connects to port @var{baseport}+@var{displaynumber} at @var{hostname}. By default @var{baseport} is 5703. The drive parameter is to distinguish among multiple drives associated with a single display (only mtools versions more recent than 3.9.11) @subsection Examples: The following starts a floppy daemon giving access to @file{/dev/fd0}, listening on the default port 5703, tied to the default X servers: @example floppyd -d /dev/fd0 @end example Each of the following starts a floppy daemon giving access to @file{/dev/fd1}, tied to the :1 local X servers, and listening on port 5704. We assume that the local host is named @code{hitchhiker}. @example floppyd -d /dev/fd0 floppyd -d -x :1 -p 5704 /dev/fd0 @end example If you want to start floppyd by @code{inetd} instead of running it as a daemon, insert the following lines into @file{/etc/services}: @example # floppy daemon floppyd-0 5703/tcp # floppy daemon for X server :0 floppyd-1 5704/tcp # floppy daemon for X server :1 @end example And insert the following into @file{/etc/inetd.conf} (assuming that you have defined a user named floppy in your @file{/etc/passwd}): @example # floppy daemon floppyd-0 stream tcp wait floppy /usr/sbin/floppyd floppyd /dev/fd0 floppyd-1 stream tcp wait floppy /usr/sbin/floppyd floppyd -x :1 /dev/fd0 @end example Note that you need to supply the X display names for the second floppyd. This is because the port is opened by inetd.conf, and hence floppyd cannot know its number to interfere the display number. On the client side, insert the following into your @file{~/.mtoolsrc} to define a drive letter accessing floppy drive in your X terminal: @example drive x: file="$DISPLAY" remote @end example If your X terminal has more than one drive, you may access the additional drives as follows: @example drive y: file="$DISPLAY//1" remote drive z: file="$DISPLAY//2" remote @end example @node floppyd_installtest, mattrib, floppyd, Commands @section Floppyd_installtest @pindex floppyd_installtest @cindex X terminal @cindex remote floppy access @code{Floppyd_installtest} is used to check for the presence of a running floppyd daemon. This is useful, if you have a small front-end script to mtools, which decides whether to use floppyd or not. @code{floppyd_installtest} [@code{-f}] Connect-String If the @code{-f} option is specified, @code{floppyd_installtest} does a full X-Cookie authentication and complains if this does not work. The connect-String has the format described in the floppyd-section: @var{hostname}@code{:}@var{displaynumber}[@code{/}@var{baseport}] @node mattrib, mbadblocks, floppyd_installtest, Commands @section Mattrib @pindex mattrib @cindex Changing file attributes @cindex Hidden files @cindex Read-only files (changing the attribute) @cindex System files @cindex Archive bit @code{Mattrib} is used to change MS-DOS file attribute flags. It has the following syntax: @code{mattrib} [@code{-a|+a}] [@code{-h|+h}] [@code{-r|+r}] [@code{-s|+s}] [@code{-/}] [@code{-p}] [@code{-X}] @var{msdosfile} [ @var{msdosfiles} @dots{} ] @code{Mattrib} adds attribute flags to an MS-DOS file (with the `@code{+}' operator) or remove attribute flags (with the `@code{-}' operator). @code{Mattrib} supports the following attribute bits: @table @code @item a Archive bit. Used by some backup programs to indicate a new file. @item r Read-only bit. Used to indicate a read-only file. Files with this bit set cannot be erased by @code{DEL} nor modified. @item s System bit. Used by MS-DOS to indicate a operating system file. @item h Hidden bit. Used to make files hidden from @code{DIR}. @end table @code{Mattrib} supports the following command line flags: @table @code @item / Recursive. Recursively list the attributes of the files in the subdirectories. @item X Concise. Prints the attributes without any whitespace padding. If neither the "/" option is given, nor the @var{msdosfile} contains a wildcard, and there is only one MS-DOS file parameter on the command line, only the attribute is printed, and not the filename. This option is convenient for scripts @item p Replay mode. Outputs a series of mformat commands that will reproduce the current situation, starting from a situation as left by untarring the MS-DOS file system. Commands are only output for attribute settings that differ from the default (archive bit set for files, unset for directories). This option is intended to be used in addition to tar. The @code{readonly} attribute is not taken into account, as tar can set that one itself. @end table @node mbadblocks, mcat, mattrib, Commands @section Mbadblocks @pindex mbadblocks @cindex Marking blocks as bad @cindex Bad blocks @cindex Read errors The @code{mbadblocks} command is used to mark some clusters on an MS-DOS filesystem bad. It has the following syntax: @code{mbadblocks} [@code{-s} @var{sectorlist}|@code{-c} @var{clusterlist}|-w] @var{drive}@code{:} If no command line flags are supplied, @code{Mbadblocks} scans an MS-DOS filesystem for bad blocks by simply trying to read them and flag them if read fails. All blocks that are unused are scanned, and if detected bad are marked as such in the FAT. This command is intended to be used right after @code{mformat}. It is not intended to salvage data from bad disks. @subsection Command line options @table @code @item c @var{file} Use a list of bad clusters, rather than scanning for bad clusters itself. @item s @var{file} Use a list of bad sectors (counted from beginning of filesystem), rather than trying for bad clusters itself. @item w Write a random pattern to each cluster, then read it back and flag cluster as bad if mismatch. Only free clusters are tested in such a way, so any file data is preserved. @end table @subsection Bugs @code{Mbadblocks} should (but doesn't yet :-( ) also try to salvage bad blocks which are in use by reading them repeatedly, and then mark them bad. @node mcat, mcd, mbadblocks, Commands @section Mcat The @code{mcat} command is used to copy an entire disk image from or to the floppy device. It uses the following syntax: @code{mcat} [@code{-w}] @var{drive}@code{:} @pindex mcat @cindex Copying an entire disk image @cindex Disk image @cindex Floppyd cat @code{Mcat} performs the same task as the Unix @code{cat} command. It is included into the mtools package, since @code{cat} cannot access remote floppy devices offered by the mtools floppy daemon. Now it is possible to create boot floppies remotely. The default operation is reading. The output is written to stdout. If the @code{-w} option is specified, mcat reads a disk-image from stdin and writes it to the given device. @strong{Use this carefully!} Because of the low-level nature of this command, it will happily destroy any data written before on the disk without warning! @node mcd, mclasserase, mcat, Commands @section Mcd @pindex mcd @cindex Directory (changing) @cindex Working directory @cindex Current working directory (changing the) @cindex Default directory (changing the) @cindex Mcwd file The @code{mcd} command is used to change the mtools working directory on the MS-DOS disk. It uses the following syntax: @example @code{mcd} [@var{msdosdirectory}] @end example Without arguments, @code{mcd} reports the current device and working directory. Otherwise, @code{mcd} changes the current device and current working directory relative to an MS-DOS file system. The environmental variable @code{MCWD} may be used to locate the file where the device and current working directory information is stored. The default is @file{$HOME/.mcwd}. Information in this file is ignored if the file is more than 6 hours old. @code{Mcd} returns 0 on success or 1 on failure. Unlike MS-DOS versions of @code{CD}, @code{mcd} can be used to change to another device. It may be wise to remove old @file{.mcwd} files at logout. @node mclasserase, mcopy, mcd, Commands @section Mclasserase @pindex mclasserase @cindex Memory Card @cindex Physically erase The @code{mclasserase} command is used to wipe memory cards by overwriting it three times: first with @code{0xff}, then with @code{0x00}, then with @code{0xff} again. The command uses the following syntax: @example @code{mclasserase} [@code{-d}] @var{msdosdrive} @end example MS-DOS drive is optional, if none is specified, use @code{A:}. If more than one drive are specified, all but the last are ignored. @code{Mclasserase} accepts the following command line options: @table @code @item d Stop after each erase cycle, for testing purposes @item p Not yet implemented @end table @code{Mclasserase} returns 0 on success or -1 on failure. @node mcopy, mdel, mclasserase, Commands @section Mcopy @pindex mcopy @cindex Reading MS-DOS files @cindex Writing MS-DOS files @cindex Copying MS-DOS files @cindex Concatenating MS-DOS files @cindex Text files @cindex CR/LF conversions The @code{mcopy} command is used to copy MS-DOS files to and from Unix. It uses the following syntax: @example @code{mcopy} [@code{-bspanvmQT}] [@code{-D} @var{clash_option}] @var{sourcefile} @var{targetfile} @code{mcopy} [@code{-bspanvmQT}] [@code{-D} @var{clash_option}] @var{sourcefile} [ @var{sourcefiles}@dots{} ] @var{targetdirectory} @code{mcopy} [@code{-tnvm}] @var{MSDOSsourcefile} @end example @code{Mcopy} copies the specified file to the named file, or copies multiple files to the named directory. The source and target can be either MS-DOS or Unix files. The use of a drive letter designation on the MS-DOS files, 'a:' for example, determines the direction of the transfer. A missing drive designation implies a Unix file whose path starts in the current directory. If a source drive letter is specified with no attached file name (e.g. @code{mcopy a: .}), all files are copied from that drive. If only a single, MS-DOS source parameter is provided (e.g. "mcopy a:foo.exe"), an implied destination of the current directory (`@code{.}') is assumed. A filename of `@code{-}' means standard input or standard output, depending on its position on the command line. @code{Mcopy} accepts the following command line options: @table @code @item t Text file transfer. Mcopy translates incoming carriage return/line feeds to line feeds when copying from MS-DOS to Unix, and vice-versa when copying from Unix to MS-DOS. @item b Batch mode. Optimized for huge recursive copies, but less secure if a crash happens during the copy. @item s Recursive copy. Also copies directories and their contents @item p Preserves the attributes of the copied files @item Q When mcopying multiple files, quits as soon as one copy fails (for example due to lacking storage space on the target disk) @item a Text (ASCII) file transfer. @code{ASCII} translates incoming carriage return/line feeds to line feeds. @item T Text (ASCII) file transfer with character set conversion. Differs from @code{-a} in the @code{ASCII} also translates incoming PC-8 characters to ISO-8859-1 equivalents as far as possible. When reading DOS files, untranslatable characters are replaced by '@code{#}'; when writing DOS files, untranslatable characters are replaced by '@code{.}'. @item n No confirmation when overwriting Unix files. @code{ASCII} doesn't warn the user when overwriting an existing Unix file. If the target file already exists, and the @code{-n} option is not in effect, @code{mcopy} asks whether to overwrite the file or to rename the new file (@ref{name clashes}) for details). In order to switch off confirmation for DOS files, use @code{-o}. @item m Preserve the file modification time. @item v Verbose. Displays the name of each file as it is copied. @end table @subsection Bugs Unlike MS-DOS, the '+' operator (append) from MS-DOS is not supported. However, you may use @code{mtype} to produce the same effect: @example mtype a:file1 a:file2 a:file3 >unixfile mtype a:file1 a:file2 a:file3 | mcopy - a:msdosfile @end example @node mdel, mdeltree, mcopy, Commands @section Mdel @pindex mdel @cindex removing MS-DOS files @cindex erasing MS-DOS files @cindex deleting MS-DOS files The @code{mdel} command is used to delete an MS-DOS file. Its syntax is: @display @code{mdel} [@code{-v}] @var{msdosfile} [ @var{msdosfiles} @dots{} ] @end display @code{Mdel} deletes files on an MS-DOS file system. @code{Mdel} asks for verification prior to removing a read-only file. @node mdeltree, mdir, mdel, Commands @section Mdeltree @pindex mdeltree @cindex removing an MS-DOS directory recursively @cindex erasing an MS-DOS directory recursively @cindex deleting an MS-DOS directory recursively @cindex recursively removing an MS-DOS directory The @code{mdeltree} command is used to delete an MS-DOS file. Its syntax is: @display @code{mdeltree} [@code{-v}] @var{msdosdirectory} [@var{msdosdirectories}@dots{}] @end display @code{Mdeltree} removes a directory and all the files and subdirectories it contains from an MS-DOS file system. An error occurs if the directory to be removed does not exist. @node mdir, mdu, mdeltree, Commands @section Mdir @pindex mdir @cindex Read-only files (listing them) @cindex Listing a directory @cindex Directory listing The @code{mdir} command is used to display an MS-DOS directory. Its syntax is: @code{mdir} [@code{-/}] [@code{-f}] [@code{-w}] [@code{-a}] [@code{-b}] @var{msdosfile} [ @var{msdosfiles}@dots{}] @code{Mdir} displays the contents of MS-DOS directories, or the entries for some MS-DOS files. @code{Mdir} supports the following command line options: @table @code @item / Recursive output, just like MS-DOS' @code{-s} option @item w Wide output. With this option, @code{mdir} prints the filenames across the page without displaying the file size or creation date. @item a Also list hidden files. @item f Fast. Do not try to find out free space. On larger disks, finding out the amount of free space takes up some non trivial amount of time, as the whole FAT must be read in and scanned. The @code{-f} flag bypasses this step. This flag is not needed on FAT32 file systems, which store the size explicitly. @item b Concise listing. Lists each directory name or filename, one per line (including the filename extension). This switch displays no heading information and no summary. Only a newline separated list of pathnames is displayed. @end table An error occurs if a component of the path is not a directory. @node mdu, mformat, mdir, Commands @section Mdu @pindex mdu @cindex Space occupied by directories and files @cindex du @cindex Listing space occupied by directories and files @cindex Occupation of space by directories and files @code{Mdu} is used to list the space occupied by a directory, its subdirectories and its files. It is similar to the @code{du} command on Unix. The unit used are clusters.

The following options are supported: (The S, 2, 1 and M options may not exist if this copy of mtools has been compiled without the USE_2M option) The following options are the same as for MS-DOS's format command: @comment xMANoptions @table @code @item v Specifies the volume label. A volume label identifies the disk and can be a maximum of 11 characters. If you omit the -v switch, mformat will assign no label to the disk. @item f Specifies the size of the DOS file system to format. Only a certain number of predefined sizes are supported by this flag; for others use the -h/-t/-s flags. The following sizes are supported: @table @asis @item 160 160K, single-sided, 8 sectors per track, 40 cylinders (for 5 1/4 DD) @item 180 160K, single-sided, 9 sectors per track, 40 cylinders (for 5 1/4 DD) @item 320 320K, double-sided, 8 sectors per track, 40 cylinders (for 5 1/4 DD) @item 360 360K, double-sided, 9 sectors per track, 40 cylinders (for 5 1/4 DD) @item 720 720K, double-sided, 9 sectors per track, 80 cylinders (for 3 1/2 DD) @item 1200 1200K, double-sided, 15 sectors per track, 80 cylinders (for 5 1/4 HD) @item 1440 1440K, double-sided, 18 sectors per track, 80 cylinders (for 3 1/2 HD) @item 2880 2880K, double-sided, 36 sectors per track, 80 cylinders (for 3 1/2 ED) @end table @item t Specifies the number of tracks on the disk. @item T Specifies the number of total sectors on the disk. Only one of these 2 options may be specified (tracks or total sectors) @item h The number of heads (sides). @item s Specifies the number of sectors per track. If the 2m option is given, number of 512-byte sector equivalents on generic tracks (i.e. not head 0 track 0). If the 2m option is not given, number of physical sectors per track (which may be bigger than 512 bytes). @item 1 Formats a single side (equivalent to -h 1) @item 4 Formats a 360K double-sided disk (equivalent to -f 360). When used together with -the 1 switch, this switch formats a 180K disk @item 8 Formats a disk with 8 sectors per track. @end table MS-DOS format's @code{q}, @code{u} and @code{b} options are not supported, and @code{s} has a different meaning. The following options are specific to mtools: @table @code @item F Format the partition as FAT32. @item S The size code. The size of the sector is 2 ^ (sizecode + 7). @item X formats the disk as an XDF disk. @xref{XDF}, for more details. The disk has first to be low-level formatted using the xdfcopy utility included in the fdutils package. XDF disks are used for instance for OS/2 install disks. @item 2 2m format. The parameter to this option describes the number of sectors on track 0, head 0. This option is recommended for sectors bigger than normal. @item 3 don't use a 2m format, even if the current geometry of the disk is a 2m geometry. @item 0 Data transfer rate on track 0 @item A Data transfer rate on tracks other than 0 @item M software sector size. This parameter describes the sector size in bytes used by the MS-DOS file system. By default it is the physical sector size. @item N Uses the requested serial number, instead of generating one automatically @item a If this option is given, an Atari style serial number is generated. Ataris store their serial number in the OEM label. @item C creates the disk image file to install the MS-DOS file system on it. Obviously, this is useless on physical devices such as floppies and hard disk partitions, but is interesting for image files. @item H number of hidden sectors. This parameter is useful for formatting hard disk partition, which are not aligned on track boundaries (i.e. first head of first track doesn't belong to the partition, but contains a partition table). In that case the number of hidden sectors is in general the number of sectors per cylinder. This is untested. @item I Sets the fsVersion id when formatting a FAT32 drive. In order to find this out, run minfo on an existing FAT32 drive, and mail me about it, so I can include the correct value in future versions of mtools. @item c Sets the size of a cluster (in sectors). If this cluster size would generate a FAT that too big for its number of bits, mtools automatically increases the cluster size, until the FAT is small enough. If no cluster size is specified explicitly, mtools uses a default value as described in section ``Number of sectors per cluster'' below. @item d Sets the number of FAT copies. Default is 2. This setting can also be specified using the @code{MTOOLS_NFATS} environment variable. @item r Sets the size of the root directory (in sectors). Only applicable to 12 and 16 bit FATs. This setting can also be specified using the @code{MTOOLS_DIR_LEN} environment variable. @item L Sets the length of the FAT. @item B Use the boot sector stored in the given file or device, instead of using its own. Only the geometry fields are updated to match the target disks parameters. @item k Keep the existing boot sector as much as possible. Only the geometry fields and other similar file system data are updated to match the target disks parameters. @item K Sets the sector number where the backup of the boot sector should be stored (only relevant on FAT32). @item R Sets the number of reserved sectors for this filesystem. This must be at least 1 for non-FAT32 disks, and at least 3 for FAT disks (in order to accommodate the boot sector, the info sector and the backup boot sector). @item m Use a non-standard media descriptor byte for this disk. The media descriptor is stored at position 21 of the boot sector, and as first byte in each FAT copy. Using this option may confuse DOS or older mtools version, and may make the disk unreadable. Only use if you know what you are doing. @end table To format a diskette at a density other than the default, you must supply (at least) those command line parameters that are different from the default. @code{Mformat} returns 0 on success or 1 on failure. It doesn't record bad block information to the Fat, use @code{mbadblocks} for that. @subsection Number of sectors per cluster If the user indicates no cluster size, mformat figures out a default value for it. For FAT32 it uses the following table to determine the number of sectors per cluster, depending on the total number of sectors on the filesystem. more than 32*1024*1024*2: 64 sectors@* between 16*1024*1024*2 and 32*1024*1024*2: 32 sectors@* between 8*1024*1024*2 and 16*1024*1024*2: 16 sectors@* between 260*1024*2 and 81024*1024*2: 1 sectors@* This is derived from information on page 20 of Microsoft's @code{fatgen103} document, which currently can be found at the following address: @code{https://staff.washington.edu/dittrich/misc/fatgen103.pdf} For FAT12 and FAT16, mformat uses an iterative approach, where it starts with a set value, which it doubles until it is able to fill up the disk using that cluster size and a number of cluster less than the maximum allowed. The starting value is 1 for disks with one head or less than 2000 sectors, and 2 for disks with more than one head, and more than 2000 sectors. The number of sectors per cluster cannot go beyond 128. @node mkmanifest, minfo, mformat, Commands @section Mkmanifest @pindex mkmanifest @cindex packing list The @code{mkmanifest} command is used to create a shell script (packing list) to restore Unix filenames. Its syntax is: @code{mkmanifest} [ @var{files} ] @code{Mkmanifest} creates a shell script that aids in the restoration of Unix filenames that got clobbered by the MS-DOS filename restrictions. MS-DOS filenames are restricted to 8 character names, 3 character extensions, upper case only, no device names, and no illegal characters. The mkmanifest program is compatible with the methods used in @code{pcomm, arc,} and @code{mtools} to change perfectly good Unix filenames to fit the MS-DOS restrictions. This command is only useful if the target system which will read the diskette cannot handle VFAT long names. @subsection Example You want to copy the following Unix files to a MS-DOS diskette (using the @code{mcopy} command). @example very_long_name 2.many.dots illegal: good.c prn.dev Capital @end example @code{ASCII} converts the names to: @example very_lon 2xmany.dot illegalx good.c xprn.dev capital @end example The command: @example mkmanifest very_long_name 2.many.dots illegal: good.c prn.dev Capital >manifest @end example would produce the following: @example mv very_lon very_long_name mv 2xmany.dot 2.many.dots mv illegalx illegal: mv xprn.dev prn.dev mv capital Capital @end example Notice that "good.c" did not require any conversion, so it did not appear in the output. Suppose I've copied these files from the diskette to another Unix system, and I now want the files back to their original names. If the file "manifest" (the output captured above) was sent along with those files, it could be used to convert the filenames. @subsection Bugs The short names generated by @code{mkmanifest} follow the old convention (from mtools-2.0.7) and not the one from Windows 95 and mtools-3.0. @node minfo, mlabel, mkmanifest, Commands @section Minfo @pindex minfo @cindex mformat parameters @cindex getting parameters of a MS-DOS file system The @code{minfo} command prints the parameters of a MS-DOS file system, such as number of sectors, heads and cylinders.

If @var{new_label} is not given, and if neither the @code{c} nor the @code{s} options are set, it prompts the user for a new volume label. To delete an existing volume label, press return at the prompt. The label is limited to 11 single-byte characters, e.g. @code{Name1234567}. Reasonable care is taken to create a valid MS-DOS volume label. If an invalid label is specified, @code{mlabel} changes the label (and displays the new label if the verbose mode is set). @code{Mlabel} returns 0 on success or 1 on failure. Mlabel supports the following options: @table @code @item c Clears an existing label, without prompting the user @item s Shows the existing label, without prompting the user. @item n Assigns a new (random) serial number to the disk @item N @var{serial} Sets the supplied serial number.

If verbose (@code{-v}) is also set, prints the current partition table. @item r Removes the partition described by @var{drive}. @item I Initializes the partition table, and removes all partitions. @item c Creates the partition described by @var{drive}. @item a "Activates" the partition, i.e. makes it bootable. Only one partition can be bootable at a time. @item d "Deactivates" the partition, i.e. makes it unbootable. @end table If no operation is given, the current settings are printed. For partition creations, the following options are available: @table @code @item s @var{sectors} The number of sectors per track of the partition (which is also the number of sectors per track for the whole drive). @item h @var{heads} The number of heads of the partition (which is also the number of heads for the whole drive). By default, the geometry information (number of sectors and heads) is figured out from neighboring partition table entries, or guessed from the size. @item t @var{cylinders} The number of cylinders of the partition (not the number of cylinders of the whole drive. @item b @var{begin} The starting offset of the partition, expressed in sectors. If begin is not given, mpartition lets the partition begin at the start of the disk (partition number 1), or immediately after the end of the previous partition. @item l @var{length} The size (length) of the partition, expressed in sectors. If end is not given, mpartition figures out the size from the number of sectors, heads and cylinders. If these are not given either, it gives the partition the biggest possible size, considering disk size and start of the next partition. @end table The following option is available for all operation which modify the partition table: @table @code @item f Usually, before writing back any changes to the partition, mpartition performs certain consistency checks, such as checking for overlaps and proper alignment of the partitions. If any of these checks fails, the partition table is not changes. The @code{-f} allows you to override these safeguards. @end table The following options are available for all operations: @table @code @item v Together with @code{-p} prints the partition table as it is now (no change operation), or as it is after it is modified. @item vv If the verbosity flag is given twice, mpartition will print out a hexdump of the partition table when reading it from and writing it to the device. @end table The following option is available for partition table initialization: @table @code @item B @var{bootSector} Reads the template master boot record from file @var{bootSector}. @end table @subsection Choice of partition type Mpartition proceeds as follows to pick a type for the partition: @itemize - @item FAT32 partitions are assigned type 0x0C (``@code{Win95 FAT32, LBA}'') @item For all others, if the partition fits entirely within the 65536 sector of the disk, assign 0x01 (``@code{DOS FAT12, CHS}'') for FAT12 partition and 0x04 (``@code{DOS FAT16, CHS}'') for FAT16 partitions @item If not covered by the above, assign 0x06 (``@code{DOS BIG FAT16 CHS}'') if partition fits entirely within the first 1024 cylinders (CHS mode) @item All remaining cases get 0x0E (``@code{Win95 BIG FAT16, LBA}'') @end itemize If number of fat bits is not known (not specified in drive's definition), then FAT12 is assumed for all drives with less than 4096 sectors, and FAT16 for those with more than 4096 sectors. This corresponds more or less to the definitions outlined at @code{https://en.wikipedia.org/wiki/Partition_type#List_of_partition_IDs} and @code{https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-2000-server/cc977219(v=technet.10)}, with two notable differences: @itemize - @item If fat bits are unknown, the reference documents consider drives with less than 32680 sectors to be FAT12. Mtools uses 4096 sectors as the cutoff point, as older versions of DOS only support FAT12 on disks with less than 4096 sectors (and these older versions are the ones which would be most likely to use FAT12 in the first place). @item The reference documents use a 8GB (wikipedia) or a 4GB (Microsoft) cutoff between 0x06 (@code{DOS BIG FAT16 CHS}) and 0x0E. Mtools uses 1024 cylinders. This is because any partition beyond 1024 cylinders must be LBA and cannot be CHS. 8GB works out to be the biggest capacity which can be represented as CHS (63 sectors, 255 heads and 1024 cylinders). 4GB is the capacity limit for windows 2000, so it makes sense that a documentation for windows 2000 would specify this as the upper limit for any partition type. @end itemize @node mrd, mren, mpartition, Commands @section Mrd @pindex mrd @cindex Removing a directory @cindex Erasing a directory @cindex Deleting a directory @cindex Directory removing @cindex Subdirectory removing The @code{mrd} command is used to remove an MS-DOS subdirectory.

To invoke it, just type @code{mtoolstest} without any arguments. @code{Mtoolstest} reads the mtools configuration files, and prints the cumulative configuration to @code{stdout}. The output can be used as a configuration file itself (although you might want to remove redundant clauses). You may use this program to convert old-style configuration files into new style configuration files. @node mtype, mzip, mtoolstest, Commands @section Mtype The @code{mtype} command is used to display contents of an MS-DOS file. Its syntax is: @display @code{mtype} [@code{-ts}] @var{msdosfile} [ @var{msdosfiles}@dots{} ] @end display @code{Mtype} displays the specified MS-DOS file on the screen.

If you have forgotten the password, you can get rid of it by low-level formatting the disk (using your SCSI adapter's BIOS setup). The ZipTools disk shipped with the drive is also password protected. On MS-DOS or on a Mac, this password is automatically removed once the ZipTools have been installed. From various articles posted to Usenet, I learned that the password for the tools disk is @code{APlaceForYourStuff}@footnote{To see the articles, search for @code{APlaceForYourStuff} using Google Groups}. Mzip knows about this password, and tries it first, before prompting you for a password. Thus @code{mzip -w z:} unlocks the tools disk@footnote{I didn't know about this yet when I bought my own Zip drive. Thus I ended up reformatting my tools disk, and hence I haven't had the opportunity to test the password yet. If anybody still has their tools disk with the original password, could you try it out? Thanks in advance}. The tools disk is formatted in a special way so as to be usable both in a PC and in a Mac. On a PC, the Mac file system appears as a hidden file named @file{partishn.mac}. You may erase it to reclaim the 50 Megs of space taken up by the Mac file system. @subsection Bugs This command is a big kludge. A proper implementation would take a rework of significant parts of mtools, but unfortunately I don't have the time for this right now. The main downside of this implementation is that it is inefficient on some architectures (several successive calls to mtools, which defeats mtools' caching). @node Compiling mtools, Porting mtools, Commands, Top @chapter Architecture specific compilation flags @cindex XDF disks (compile time configuration) @cindex Solaris (compile time configuration of vold) @cindex Vold (compile time configuration) @cindex Compile time configuration To compile mtools, first invoke @code{./configure} before @code{make}.

For most common systems, default drives are already defined. If you want to add default drives for a still unsupported system, run configuration.guess, to see which identification autoconf uses for that system. This identification is of the form cpu-vendor-os (for example sparc-sun-sunos). The cpu and the OS parts are passed to the compiler as preprocessor flags. The OS part is passed to the compiler in three forms. @enumerate @item The complete OS name, with dots replaced by underscores. SCO3.2v2 would yield sco3_2v2 @item The base OS name. SCO3.2v2 would yield Sco @item The base OS name plus its major version. SCO3.2v2 would yield Sco3 @end enumerate All three versions are passed, if they are different. To define the devices, use the entries for the systems that are already present as templates. In general, they have the following form: @example #if (defined (my_cpu) && defined(my_os)) #define predefined_devices struct device devices[] = @{ @{ "/dev/first_drive", 'drive_letter', drive_description@}, @dots{} @{ "/dev/last_drive", 'drive_letter', drive_description@} @} #define INIT_NOOP #endif @end example "/dev/first_drive" is the name of the device or image file representing the drive. Drive_letter is a letter ranging from a to z giving access to the drive. Drive_description describes the type of the drive: @table @code @item ED312 extra density (2.88M) 3 1/2 disk @item HD312 high density 3 1/2 disk @item DD312 double density 3 1/2 disk @item HD514 high density 5 1/4 disk @item DD514 double density 5 1/4 disk @item DDsmall 8 sector double density 5 1/4 disk @item SS514 single sided double density 5 1/4 disk @item SSsmall single sided 8 sector double density 5 1/4 disk @item GENFD generic floppy drive (12 bit FAT) @item GENHD generic hard disk (16 bit FAT) @item GEN generic device (all parameters match) @item ZIPJAZ(flags) generic ZIP drive using normal access. This uses partition 4. @code{Flags} are any special flags to be passed to open. @item RZIPJAZ(flags) generic ZIP drive using raw SCSI access. This uses partition 4. @code{Flags} are any special flags to be passed to open. @item REMOTE the remote drive used for floppyd. Unlike the other items, this macro also includes the file name ($DISPLAY) and the drive letter (X) @end table Entries may be described in more detail: @example fat_bits,open_flags,cylinders,heads,sectors,DEF_ARG @end example or, if you need to describe an offset (file system doesn't start at beginning of file system) @example fat_bits, open_flags, cylinders, heads, sectors, offset, DEF_ARG0 @end example @table @code @item fat_bits is either 12, 16 or 0. 0 means that the device accepts both types of FAT. @item open_flags may include flags such as O_NDELAY, or O_RDONLY, which might be necessary to open the device. 0 means no special flags are needed. @item cylinders,heads,sectors describe the geometry of the disk. If cylinders is 0, the heads and sectors parameters are ignored, and the drive accepts any geometry. @item offset is used if the DOS file system doesn't begin at the start of the device or image file. This is mostly useful for Atari Ram disks (which contain their device driver at the beginning of the file) or for DOS emulator images (which may represent a partitioned device. @end table Definition of defaults in the devices file should only be done if these same devices are found on a large number of hosts of this type. In that case, could you also let me know about your new definitions, so that I can include them into the next release. For purely local file, I recommend that you use the @code{@value{SYSCONFDIR}mtools.conf} and @code{~/.mtoolsrc} configuration files. However, the devices files also allows to supply geometry setting routines. These are necessary if you want to access high capacity disks. Two routines should be supplied: @enumerate @item Reading the current parameters @example static inline int get_parameters(int fd, struct generic_floppy_struct *floppy) @end example This probes the current configured geometry, and return it in the structure generic_floppy_struct (which must also be declared). Fd is an open file descriptor for the device, and buf is an already filled in stat structure, which may be useful. This routine should return 1 if the probing fails, and 0 otherwise. @item Setting new parameters @example static inline int set_parameters(int fd, struct generic_floppy_struct *floppy) struct stat *buf) @end example This configures the geometry contained in floppy on the file descriptor fd. Buf is the result of a stat call (already filled in). This should return 1 if the new geometry cannot be configured, and 0 otherwise. @end enumerate A certain number of preprocessor macros should also be supplied: @table @code @item TRACKS(floppy) refers to the track field in the floppy structure @item HEADS(floppy) refers to the heads field in the floppy structure @item SECTORS(floppy) refers to the sectors per track field in the floppy structure @item SECTORS_PER_DISK(floppy) refers to the sectors per disk field in the floppy structure (if applicable, otherwise leave undefined) @item BLOCK_MAJOR major number of the floppy device, when viewed as a block device @item CHAR_MAJOR major number of the floppy device, when viewed as a character device (a.k.a. "raw" device, used for fsck) (leave this undefined, if your OS doesn't have raw devices) @end table For the truly high capacity formats (XDF, 2m, etc), there is no clean and documented interface yet. @comment MANskip 1 @node Command Index, Variable Index, Porting mtools, Top @unnumbered Command Index @printindex pg @node Variable Index, Concept Index, Command Index, Top @unnumbered Variable index @printindex vr @node Concept Index, , Variable Index, Top @unnumbered Concept index @printindex cp @comment MANend-skip 1 @comment MANend-skip 5 @bye
