A grimoire is a book of spells. If you —like me in the '90s— ever played Magic: The Gathering, then you'll already know that.
However, in this case we are not talking about conjuring unicorns or moving objects using telekinesis, but rather unlocking the forbidden powers of the command line.
The 6 spells contained in these pages are powerful commands, scripts, and similar incantations that help me every so often to complete a task in a fast, efficient way.
