Cheat allows you to create and view interactive cheatsheets on the command-line. It was designed to help remind *nix system administrators of options for commands that they use frequently, but not frequently enough to remember.
How it works:
Quote
The next time you're forced to disarm a nuclear weapon without consulting Google, you may run:You will be presented with a cheatsheet resembling:
cheat tar
# To extract an uncompressed archive:
tar -xvf /path/to/foo.tar
# To extract a .gz archive:
tar -xzvf /path/to/foo.tgz
# To create a .gz archive:
tar -czvf /path/to/foo.tgz /path/to/foo/
# To extract a .bz2 archive:
tar -xjvf /path/to/foo.tgz
# To create a .bz2 archive:
tar -cjvf /path/to/foo.tgz /path/to/foo/
To see what cheatsheets are availble, run cheat -l.
Note that, while cheat was designed primarily for *nix system administrators, it is agnostic as to what content it stores. If you would like to use cheat to store notes on your favorite cookie recipes, feel free.
