Supplying an alternative shell

If your installation decides to supply its own shell, consider doing the following tasks::

Install the alternative shell in the file system.
Set the sticky bit on and put the alternative shell in the link pack area (LPA).
Specify the path name of the shell in the PROGRAM parameter for the OMVS RACF® profile for users who want to use this as their default shell.
Customize /etc/init.options if the shell script used for system initialization will use this shell.
Identify the alternative shell in an input parameter in the /etc/init.options file.

If you are using the /etc/profile for the z/OS shell or /etc/csh.login for the tcsh shell, you might need to review them and make any necessary adjustments.
