$SHELL holds the value you are looking for.

Yet another way would be to lookup the info in /etc/passwd.

another way,

a simple ps command would get u the listing.

shell that you use currently also would be included.

Ex: let's say your default shell is /bin/ksh

and in .profile at the end; loaded another shell /bin/bash
ps command would give the listing of all shells spawned and the current shell you are in.
