pidof finds the process ID of a running program. A good way to understand things is to try them out: go to your command shell and execute "pidof sh" or "pidof bash".

In a script, you could use "$$" to get the Process ID of the script instance but pidof has the extra advantage of giving you *all* process ids of instances of the script.
