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), lzop(1), or zstd(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 unless a decompression error occurs; then exit status is 2.

       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.
