(0/T) executeing script below public

Hi, Am a bit puzzled here, we have to run a script to start/stop a server....but we have to run the script below the public folder! this is our structure /blah/theServer/public_html/ the script is located in /blah/theServer/ I noticed one funny thing about this script, it starts with: #!/bin/sh right on top but does not have a file extention...what kind of a file is this? According to the documentation the script has to be executed like so <scriptname> start (or) <scriptname> stop How do I do that? Thanks, -Ryan
