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  xdiff  invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All
       options specified are passed directly to cmp or diff.  If only one file is specified, then the  files  compared
       are  file1  (which  must  have a suffix of a supported compression format) and file1 from which the compression
       format 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 or diff 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), zdiff(1)

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