How do I change my default shell on an MSI Unix machine?

The Bourne-Again SHell (BASH) is the officially supported shell at MSI. If you prefer to use another shell, you may request the change via an MSI Support request (help@msi.umn.edu). Please be aware that some software modules (including the isub command) may not function as intended when using another shell. Furthermore, the UNIX chsh command does not work in the MSI environment
