title: How can I check for root when a user runs a perl script
body: <p>I am working a script to generate a config file that I want to store in /etc/solignis. When I run the script as a limited user it does not allow me to create the directory or write the file. So the script will have to run as sudo or a root user, how can I check if the user is a root or atleast using sudo?</p>
