Print current running shell, PID

works as well as echo $0, but also prints process id, which pts you're using. echo $SHELL doesn't always get updated when changing shells, so this is a better solution than that. Just one more variation on a theme.

having more than one shell running, anybody knows of a way to show the PID of the shell that more recently executed? My way of sorting a ps search for idle time seems cumbersome...
