{{implementation|UNIX Shell}}'''bash''' (the "Bourne Again SHell") is the GNU implementation of a [[Unix]] shell which is intended to be compatible with the original UNIX [[Bourne Shell|shell]] (/bin/sh) by [[wp:Stephen R. Bourne|Stephen R. Bourne]]. ''bash'' was primarily written and is maintained by [[wp:Brian Fox (computer programmer)|Brian Fox]] and Chet Ramey. The name follows ana FSF[[wp:Free (Software Foundation|Free Software Foundation)]] tradition for whimsical and pun-referential names.
 
In functionality ''bash'' goes well beyond the original Bourne shells and closely matches the extensions of David Korn's "[[wp:Korn shell|Korn shell]]" (''ksh'') but lacks built-in support for "associative arrays" and co-processes. However, ''bash'' also adds a number of interactive features drawn from Bill Joy's [[wp:C shell|C shell]] (including the many "bang expansion operators" for things like !! (expand to entire previous command), !-2 (expand to penultimate command), !$ (expand to last argument of previous command) etc).
