|
|
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.
