Zsh

Zsh is a powerful UNIX command interpreter that mimics the Korn shell (ksh) in terms of functionality. This software package boasts an impressive suite of enhancements designed to improve the user experience. One of its standout features is its command-line editor, which provides advanced editing capabilities to streamline inputting and executing commands.

Another great thing about Zsh is the level of customisation it provides for users. You can easily modify its behaviour to your liking, whether you want to adjust how it handles filenames or tweak its autocomplete functionality. It also includes features that C-shell (csh) users will appreciate, making the transition to Zsh seamless for those familiar with that shell.

Finally, Zsh comes with a range of extra features sourced from tcsh, which makes it an incredibly versatile shell for UNIX users. Whether you're a seasoned developer or a casual user, Zsh is a must-have tool for anyone looking to improve their UNIX workflow.
