zsh - A powerful interactive shell
The zsh shell is a command interpreter usable as an interactive login
shell and as a shell script command processor. Zsh resembles the ksh
shell (the Korn shell), but includes many enhancements. Zsh supports
command line editing, built-in spelling correction, programmable
command completion, shell functions (with autoloading), a history
mechanism, and more.
