SYNOPSIS

slack-diff [OPTION]... FILE1 FILE2

DESCRIPTION

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.

--diff PROG

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.
