XZDIFF(1)                          XZ Utils                          XZDIFF(1)



NAME
       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS
       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION
       xzcmp  and  xzdiff  invoke  cmp(1)  or diff(1) on files compressed with
       xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1).  All  options  specified
       are  passed  directly to cmp(1) or diff(1).  If only one file is speci-
       fied, then the files compared are file1 (which must have a suffix of  a
       supported compression format) and file1 from which the compression for-
       mat suffix has been stripped.  If two files are  specified,  then  they
       are  uncompressed  if necessary and fed to cmp(1) or diff(1).  The exit
       status from cmp(1) or diff(1) is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with
       LZMA Utils.

SEE ALSO
       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1)

BUGS
       Messages  from  the cmp(1) or diff(1) programs refer to temporary file-
       names instead of those specified.
