RedHat Detect current shell inside a script

I wish to print my current shell which happens to be bash in my script check.sh

more check.sh
Code:

echo $0
echo `ps -p $$`



But instead of printing
Quote:
bash
it prints check.sh i.e the name of the script for both the commands.

Can you please suggest how to print the current shell i m on inside the script ?

I am on Linux OS.

Code:
echo $SHELL

or
Code:
echo ${SHELL##*/}

for just the program name without the path.

If you have /proc available you could do

Code:
readlink /proc/$$/exe
