How can I translate a shell script to Perl?

Question

I have a shell script, pretty big one. Now my boss says I must rewrite it in Perl. Is there any way to write a Perl script and use the existing shell code as is in my Perl scrip

Answer 1

You could start your "Perl" script with:

#!/bin/bash

Then, assuming bash was installed at that location, perl would automatically invoke the bash interpretor to run it.

Edit: Or maybe the OS would intercept the call and stop it getting to Perl. I'm finding it hard to track down the documentation on how this actually works. Comments to documentation would be welcomed.
