Need help with Scripting diff command
Here is where I am at so far.....
-------------------------
#!/bin/bash
echo "Enter the output file name"
read output_file
echo "Enter the Orginal file Name"
read write_file
d= ' diff $write_file $output_file '
if $d = 1 ;then

slack-diff
DIFF(1) User Commands DIFF(1)
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 miss-
ing 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.
