Note: For mac users, you'll need to open the Settings for Terminal and go to the Profiles tab, and open the Keyboard sub-tab, and check the option "Use Option as Meta key"

Bash also has some handy features that use the ! (bang) to allow you to do some funky stuff with bash commands.
- !! - run last command
- !blah – run the most recent command that starts with ‘blah’ (e.g. !ls)
- !blah:p – print out the command that !blah would run (also adds it as the latest command in the command history)
- !$ – the last word of the previous command (same as Alt + .)
- !$:p – print out the word that !$ would substitute
- !* – the previous command except for the last word (e.g. if you type ‘find some_file.txt /‘, then !* would give you ‘find some_file.txt‘)
- !:p – print out what ! would substitute
There is one more handy thing you can do. This involves using the ^^ ‘command’. If you type a command and run it, you can re-run the same command but substitute a piece of text for another piece of text using ^^ e.g.:
$ ls -al
