[root:inderweb.com]!/usr/bin/php -q

.This is to tell the shell interprator(kernal) that we are using php from bin directory for executing lines of code in script.To get started with a simple php code in shell do following steps:-

• Open shell prompt and go to your directory . e.g [root:inderweb.com ~]
