Question How to tell which shell is running a script

I've been searching for a while and haven't found this answer anywhere.

How can I tell which shell is running my script from within the script? For example, I have lots of older scripts that we are porting to a new Linux system. Many of the scripts start with ":" alone on a line, which I think long ago forced /bin/sh.

Is there a way to tell within the script what it's being interpreted by? I tried "ps", but that only shows the name of the script.

Thanks,

Sean.
