# echo $SHELL
gives you the actual shell. If you have opend another one e.g. ksh from there then you can type
# echo $$
and look for the named process id. It will give you the named shell information

SHELL is only set by login and not the shell. As you said, $0 should work.

Why do you care what the current shell is? All scripts should force a shell. And if you want to know the current shell, type a bogus command.

>Avinash: echo $$ and look for the named process id.

Something like:
UNIX95=EXTENDED_PS ps -p $$ -ocomm=

Hi,
here is the command to check which shell you are using

[suraj@rspc521 root]# echo $SHELL
/bin/bash
