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.
The next time you're forced to disarm a nuclear weapon without consulting Google, you may run:cheat tarYou will be presented with a cheatsheet resembling:# 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.
