The time has come to leave Hogwarts, young wizard! We wrap up our ten-part series on becoming a command-line wizard with a look at more utilities you should know.

We're starting to wrap things up with the Wizard series. This time around we expand on the utilities that should be at your fingertips.

Before you reach for that scripting language, make sure you're making the most of the shell utilities that you have at your fingertips!

A true wizard doesn't just run processes, a true wizard knows how to communicate with those processes through signals to stop, restart, and even kill processes.

This may sound like arcane and obscure knowledge, but if you follow along, you'll be managing your processes like an adept in no time.

Last month's column, the second in this series of obscure Linux features that wizards should know, introduced Standard I/O.

This month we'll see how to take advantage of Standard I/O from a shell-- including an example using named pipes (FIFOs).
