Zsh
Zsh is the capricious monarch of the command-line realm, beguiling users with elegant completions and labyrinthine configurations. Yet it stubbornly refuses to cooperate when most needed, reducing beginners to tears with inscrutable errors. Its aura of boundless power symbolizes freedom, but in truth it lures one into a maze of dotfiles where sanity goes to die. The kaleidoscope of prompt symbols is a taunting grin, reserved only for those daring enough to master its arcane art.
