Perl path?

I’m trying to set up a download counter script for my site. I have already checked the knowledge base and found the path to Perl is /usr/bin/perl.

My question is do I have to add anything to that path or leave it as is. What I mean is do I need to add my domain name or username or anything to it.

The script already has #!/usr/bin/perl but should the #! stay there as well?

Any help is appreciated.

Yep, keep the #!, the first line of the script should read:
All the best,

Thanks so much!!
