hash bang slash bin slash bash

Defined on Everything2 as:

The "accepted" pronunciation of invoking the Bourne Again SHell, or Bash. #!/bin/bash

You used that incantation in the git hooks exercise. In general, when you want a file in a *nix system to be executable, change it's permissions to +x (aka chmod u+x or chmod a+x) and then add a special line at the top that tells the shell how to invoke the necessary interpreter. #! means "run" and the rest of the line is the absolute path to the program that will interpret the rest of the file.

So a bash script traditionally uses hash bang slash bin slash bash or #!/bin/bash, whereas a python script might use #!/usr/bin/python

You can typically find out what the absolute path for a command is by running which CMD (as in, which python)
