I tried this... but see what I got:

jmf@squeeje:~$ cat sh.sh 
#!/bin/sh
echo $0

jmf@squeeje:~$ cat bash.bash 
#!/bin/bash
echo $0

jmf@squeeje:~$ 
jmf@squeeje:~$ ./sh.sh
./sh.sh
jmf@squeeje:~$ 
jmf@squeeje:~$ ./bash.bash 
./bash.bash
jmf@squeeje:~$ 


seems that $0 simply contains the program being run and not the
interpreter that is running it...

?
