What is a Shell?

A shell is a program that helps you interact with your computer’s operating system. The shell interprets the commands that you type in a Terminal window. Although Mac computers have default shells, you can choose to use a different shell. For Mac computers, the default shell was always bash (Bourne-Again shell) up until the release of macOS Catalina, when it was replaced with zsh as the default. However, zsh is only used for new user accounts. If you upgraded your Mac or transferred to your new Mac from a backup, you may still be using bash, even if you are running macOS Catalina or later. Each shell has unique features, and some may have useful features that are missing from your current shell. For example, zsh provides autocompletion and autocorrection features that are not available in bash.
