In a former article i’ve show how to use Screen and Byobu, in short Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells) while Byobu is an elegant enhancement of the otherwise functional, plain, practical GNU Screen. Byobu includes an enhanced profile and configuration utilities for the GNU screen window manager, such as toggle-able system status notifications.

Alias are a great tool to help increment your productivity on the terminal with bash (or any shell program you’re using), but usually we are too lazy to think at what are the most common, or long commands that we use frequently and prepare an alias for them.

And so someone has done a small piece of software to do this job: aliaser

They allow to express with a few characters search for strings, characters or words, and if done well can lead to good results, but if they are wrong they can not give you any useful result, and the worst thing is that often it is difficult to understand whether or not a regepx it is written with a correct syntax to cover all the possibility.

But now as first thing let’s see what is a regular expression:

From WIkipedia
