Description:
GNU Bourne Again SHell
Bash is an sh-compatible command language interpreter that executes commands read from the standard input or from a file. Bash also incorporates useful features from the Korn and C shells (ksh and csh). . Bash is ultimately intended to be a conformant implementation of the IEEE POSIX Shell and Tools specification (IEEE Working Group 1003.2). . The Programmable Completion Code, by Ian Macdonald, is now found in the bash-completion package.
