GNU Bash

https://www.gnu.org/software/bash
Bash is the GNU Project's Bourne Again SHell, a complete implementation of the POSIX shell spec, but also with interactive command line editing, job control on architectures that support it, csh-like features such as history substitution and brace expansion, and a slew of other features.

Bash includes useful features from the Korn shell (ksh) and C shell (csh). It offers functional improvements over sh for both programming and interactive use; these include command line editing, unlimited size command history, job control, shell functions and aliases, indexed arrays of unlimited size, and integer arithmetic in any base from two to sixty-four. Bash can run most sh scripts without modification.

Documentation

For more information on the features of Bash that are new to this type of shell, see the file `doc/bashref.texi'. There is also a large Unix-style man page. The man page is the definitive description of the shell's features. See also the Bourne-Again SHell manual.

See the file POSIX for a discussion of how the Bash defaults differ from the POSIX spec and a description of the Bash `posix mode'.
