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  --nofaked-
	      iff.

       -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  --nodevnull-
	      hack.

       --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.
