Bash tips & tricks [ep. 3]: Colour your terminal!

This is the third epidose of a small series.

Description:

The days of monochrome green-on-black screens are over, in a remote shell  terminal you can have something fancier!

BAD:

bash_prompt_nocolor

GOOD:

Define a series of variables as shortcuts for color escape codes, there are plenty of examples on internet.

Use them whenever you need to highlight the output of a script, and eventually integrate them in a smart prompt (like the one I’ve blogged about sometimes ago).bash_prompt_color

The echo builtin command requires -e in order to make the colours work. When reading files, cat works, less requires -r. vi may work with some hacking, but it’s not worth to spend too much time, IMHO.
