cmd-reformat

#!/usr/bin/perl

# this program takes as its input another command set starting with a program name and followed by
# its arguments. It will normalize them to replace = with space, and print that cmd set sorted and
# ready to be either used again or compared to another set.
#
# usage:
# 1. clean the mess:
# cmd-reformat program --arg4 --arg5 tar --arg1=bar --arg3 --arg2 tar
#
# 2. compare 2 sets of cmd and find what's different in them:
# cmd-reformat program --arg4 --arg5 tar --arg1=bar --arg3 --arg2 tar > good
# cmd-reformat program --arg4 --arg5 tar --arg1=car --arg3 --arg2 tar > bad
# diff good bad
