re `interpreter' is most often "/bin/sh" or "/bin/csh". The _kernel_ regognizes this, and starts the specified interpreter, setting its effective uid if the script is setuid. Use at your own risk. Bonus for 4.2 types: A single argument may follow the `interpreter' name, if it is separated by exactly one space (aaargh..). This makes it possible to write an awk or sed script, say `foo', and run it by typing `foo', without the overhead of exec'ing a shell, like this: #! /bin/awk -f (awk commands here) The kernel tacks the filename at the end, so awk sees /bin/awk -f /u/ss/alexis/bin/foo and everything is peachy. This is a really handy trick that I have not seen used before, so I thought I'd throw it in.
