bzcmp, bzdiff - compare bzip2 compressed files

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

                                                                                                       BZDIFF(1)

Bzcmp  and  bzdiff are used to invoke the cmp or the diff program on bzip2 compressed files.  All options
       specified are passed directly to cmp or diff.  If only 1 file is specified, then the files  compared  are
       file1 and an uncompressed file1.bz2.  If two files are specified, then they are uncompressed if necessary
       and fed to cmp or diff.  The exit status from cmp or diff is preserved.
