Bash
Bash (Bourne Again SHell) is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. It has been widely adopted as the default shell for most Linux distributions and Apple's macOS (formerly OS X). Bash is a command processor that typically runs in a text window, where the user types commands that cause actions. Bash can also read commands from a file, called a script.
