Bash
Bash is a text interface that tricks you into believing you can control everything by typing cryptic incantations (commands). It causes you to forget the very syntax you thought you mastered with the slightest typo, trapping you forever in a labyrinth of learning. Occasionally it spews incomprehensible errors, forcing the ritual of a reboot as penance. Praised as simple, it ultimately lays bare human error and desire, making it the devilish shell.
