Z shell
The Z shell (zsh) is a Unix shell that can be used both as an interactive, login shell and as a powerful shell script command interpreter. Zsh can be thought of as an extended bourne shell with a large number of improvements, including some of the most useful features of bash, ksh, and tcsh.
The first version of zsh was written by Paul Falstad in 1990 when he was a student at Princeton University. The name ZSH derives from Zhong Shao, then a teaching assistant at Princeton University. Paul Falstad thought that his login name, "zsh", was a good name for a shell.
Features of note include:
- Programmable command completion that can help the user type both options and arguments for most used commands, with out-of-the-box support for several hundred commands
- Sharing of command history among all running shells
- Extended file globbing allows file specification without needing to run an external program such as "find"
- Improved variable/array handling
- Editing of multi-line commands in a single buffer
- Spelling correction
- Various compatibility modes, e.g. zsh can pretend to be a bourne shell when run as /bin/sh
- Themeable prompts, including the ability to put prompt information on the right side of the screen and have it auto-hide when typing a long command
- Fully customizable
Attesting to the sheer size of this shell is the now famous first sentence of the shell's manual page, which reads "Because zsh contains many features, the zsh manual has been split into a number of sections", and then goes on to list thirteen items.
