What is bash?
The bash shell is powerful software for Linux, Unix, and other systems. It comes as a standard part of most Linux distributions ("distros") and most Unix systems. You can even get versions that will run on MS-Windows systems (see cygwin). It is the "command line interpreter" that you get when you bring up a terminal window like Terminal or Konsole.
