You should never need to know this in a script, because (correct)
scripts should always have #! lines at the top specifying the
interpreter to use.
In practice I've never found myself needing a shell variable to let me
know in any other situation either; I know what my login shell is, and I
can use 'getent passwd | grep ^whatever-my-user-name-is' to find out if
I don't.
