Bash (the GNU Bourne Again SHell) is a Unix shell. It was built as a free replacement to the Bourne shell and includes many scripting features from other shells, such as ksh and (t)csh. When called as sh, it is intended to conform to the POSIX 1003.2 standard. Bash features include: command line editing with the readline library, command history, job control, functions & aliases, arrays, dynamic prompts, integer arithmetic, and command & filename completion. Bash is the default interactive shell on most Linux distributions and is usually available on other Unix variants. Some GNU/Linux systems even use it as the default shell /bin/sh.

• autocomplete completion of partially-entered file names, command names, options and other arguments.
• prompt showing a prompt before each command, which many users like to customize.
• readline the GNU library implementing the line editing and history handling in Bash (and other terminal applications like gdb and python).
• alias for defining shortcuts for frequently-used commands.
• array a data structure for storing items in index-able memory.
