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.

SEE ALSO

BUGS

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