NAME
slack-diff - compare file contents, modes, etc
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.
