longDescription = ''
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.
