GNU Bourne Again SHell

Bash is the shell, or command language interpreter, that will appear in the GNU operating system. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers functional improvements over sh for both programming and interactive use. In addition, most sh scripts can be run by Bash without modification. The improvements offered by BASH include:

  • Command line editing
  • Unlimited size command history
  • Job Control
  • Shell Functions and Aliases
  • Indexed arrays of unlimited size
  • Integer arithmetic in any base from two to sixty-four
