As it should. The '#' character marks a comment for bourne shell, so is
ignored. And anyhow, /bin/sh does not and should not check the magic number
of a file to see if it an a.out or coff or whatever, it accepts a text file.
However, it you try:

	/bin/sh -c ./perl-script.pl

Then you will get what I think you are trying to achieve. Notice the -c switch,
which tells sh to interpret this as a command, and so pass the perl-script.pl
file to exec(2), which is where the magick numbers are examined and the
correct interpreter selected.

'k?
