How do I find the name of the current shell?

Hello,
How to find the name of the current shell that I am working on(Whether it is csh or ksh or bsh)? Are there any specific commands to find out?
I did a search, but could not find any useful links.

I did "echo $SHELL", but this always ouputs "/sbin/sh" irrespective of which shell I am using.

Can anyone help on this?

Regards,
Murali.

SHELL always contain the login shell, if not explicitly set to another value.

Why do you need to find out the shell? You always have '#!/bin/sh' (or similar) at the top of shell scripts, so in those cases the shell is known.

Hi Murali,

Another form, from prompt, execute echo $0 or ps.
