Question: I understand that the first line of all perl scripts need to point to the location of perl itself. How do I find perl on my Unix server?

Answer: Telnet into your Unix server and then type the following command from your shell's command line:

   which perl

You'll receive a message describing location of perl, as shown in the following sample reported by the server hosting this website:

   /usr/bin/perl

For more information, see the man page for which.
