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 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(1)  or  diff(1)  is
       preserved.

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

BUGS

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