Bash

Bash is a command line shell/programming language (written by Brian Fox for the GNU Project). Its name alludes to its predecessor, the long deprecated Bourne shell. Bash can be run on most Unix like operating systems, including GNU/Linux. Bash is the default command line shell on most GNU/Linux distributions.
