What is Zsh Shell

Zsh (short for "Z Shell") is a Unix shell or command-line interpreter that is an alternative to the traditional Bourne shell (sh) and the more common Bash shell. It was developed as an extended version of the Bourne shell with additional features and enhancements.

Zsh is highly customizable and offers features such as autocompletion, spelling correction, path expansion, and advanced globbing, making it a powerful and efficient shell for advanced users and developers. It also supports plugins and themes, allowing users to customize their shell's appearance and behavior.

Zsh is available on most Unix-based systems, including Linux, macOS, and BSD, and can be installed using the system's package manager. It is also the default shell on some Linux distributions, such as macOS and some flavors of FreeBSD.

Overall, Zsh is a powerful and flexible shell that provides advanced features and customization options for users who work with the command line frequently.
