About

Zsh (the Z shell) is a unix shell.

On the scripting front, zsh and incorporates many of ksh's programming features. Zsh's syntax resembles but is not fully compatible with Bourne-style shells, though zsh has Bourne and ksh emulation modes with compatible syntax and behavior. Zsh's advanced features include many extensions to variable expansion and globbing, associative arrays and more.

For interactive use, zsh's features include advanced line edition, advanced programmable completion, spelling correction, themable prompts and more. Zsh is highly customizable, with many options and tuning possibilities.

The zsh distribution includes add-ons in the form of loadable modules and functions: zmv for batch file renaming, the FTP client zftp, regular expressions, terminal handling, and many more.
