Why do you need to?  You can put login-specific commands in your
.login.

Perhaps the question I'm reading is not quite the question you meant
to ask.  (Nitpicking is one of my more obnoxious habits, but in this
case it's the right thing to do.)  Maybe you meant, "how do I tell if
I'm executing the shell I get when I login instead of a shell script."
If so, what you *should* ask is "how do I tell if the shell's
interactive".  The answer to that is, check to see if the shell has
set the prompt variable.   For example:

	if ($?prompt) ....

Obviously, if you define your own prompt variable (which is probably
why you're asking this question in the first place; that's why *I* did)
you want to put the "if ($?prompt)" statement before the "set prompt="
statement.
