-Bash on z/OS
+## GNU Bash
+
+Bash is the GNU Project's shell—the Bourne Again SHell. This is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and the 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.
+
+The improvements offered by Bash include:
+
+command-line editing,
+unlimited size command history,
+job control,
+shell functions and aliases,
+indexed arrays of unlimited size,
+integer arithmetic in any base from two to sixty-four.
