slack-diff - compare file contents, modes, etc

       A wrapper for diff that displays file modes and other metadata changes.

       -u-U NUM  --unified[=NUM]
              Tell diff(1) to use unified output format.

       --diffPROG
              Use this program for diffing, instead of diff.

       --fakediff
              Make  a  fake diff for file modes and other things that are not file contents.  Default is on, can
              be disabled with --nofakediff.

       -r--recursive
              Recursively compare any subdirectories found.

       -N--new-file
              Treat missing files as empty.  Default is on, can be disabled with --nonew-file.

       --unidirectional-new-file
              Treat only missing files in the first directory as empty.

       --from-file
              Treat arguments as a list of files from which to read filenames to compare, two lines at a time.

       -0--null
              Use NULLs instead of newlines as the separator in --from-file mode.

       --devnullhack
              You have a version of diff that can't deal with -N when not in recursive mode, so we need to  feed
              it /dev/null instead of the missing file.  Default is on, can be disabled with --nodevnullhack.

       --version
              Output version info.

       --help Output this help.

       FILES are `FILE1 FILE2' or `DIR1 DIR2' or `DIR FILE...' or `FILE... DIR'.  If --from-file or --to-file is
       given, there are no restrictions on FILES.  If a FILE is `-', read standard input.
