Zsh

Zsh (Z shell) is a powerful UNIX command interpreter, replacing Bash/Ksh with programmable completion, extended globbing, and superior customization for interactive command-line use.

Zsh is a robust UNIX command interpreter, serving as both an interactive login shell and a shell script processor. It significantly enhances standard shells like Bash and Ksh with features including programmable command completion, extended file globbing, command-line editing, and built-in spelling correction. Adopted as the default interactive shell for macOS and Kali Linux, Zsh’s superior customization, often leveraged through frameworks like Oh My Zsh, makes it the preferred terminal environment for power users and developers.
