It is Bourne shell (sh) compatible and incorporates useful features from the Korn shell (ksh) and C shell (csh). It conforms to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. Some of bash's features are, in no particular order: editing and completion; history and command re-entry; job control; shell functions and aliases; arrays; arithmetic; ANSI C quoting; tilde expansion; brace expansion; substring capabilities; indirect variable expansion; expanded I/O capabilities; control of built-in commands; help; directory stack; POSIX mode; internationalisation; command timing. bash is the default shell on all popular GNU/Linux distributions.
