I have some questions / confusion concerning shells. I know that at different companies I have worked they have allowed different shells - korn, bash, bourne, etc.  Is there a standard for invoking each of these shells or is that defined by the admin within each system? !sh, !ksh, !bsh. 

Is there any documentation on how to set these up? A way to know which shells are being invoked by the commands?  And a way to update paramaters within each?

Thank you for your time,

Kathleen
