zsh-dev - 5.9-8+b2 main

Zsh is a UNIX command interpreter (shell) usable as an
interactive login shell and as a shell script command
processor. Of the standard shells, zsh most closely resembles
ksh but includes many enhancements. Zsh has command-line editing,
built-in spelling correction, programmable command completion,
shell functions (with autoloading), a history mechanism, and a
host of other features.
