Full directory path?

Hello,
I have 2 questions:
1/ I would like to know the full directory path to my site.

Is this the correct path?
/home/username/domains/domain.be/public_html/

2/ What is the path to perl ?

thanks

1. Correct

2. That depends from host to host. /usr/bin/perl or /usr/bin/local/perl are the most likely locations.
