Zsh is a shell that has been available since 1990 but has grown in popularity recently due to frameworks like oh-my-zsh. It can be installed on Debian/Ubuntu and Mac systems and set as the default shell. Zsh offers powerful tab autocompletion, globbing patterns for file searching, path expansion and replacement, spelling correction, and aliases. Users can customize the prompt and integrate information from programs like Python virtual environments, version control systems, and batteries. Libraries exist to configure zsh through frameworks like oh-my-zsh and prezto.
