Bash (Bourne Again shell) 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.
