 ## Calling Linux Superuser Scripts
-Linux superuser Perl scripts with elevated privileges can be started using ```gksudo``` and a special query string item ```user=root```. So if PEB finds an URL like: ```http://local-pseudodomain/perl/root-open-directory.pl?user=root```, it will call ```gksudo```, which will ask the user for the root password and start the script. Output is displayed inside PEB like the output from any other Perl script. User data is supplied to the superuser Perl scripts as the first command line argument without STDIN input or QUERY_STRING environment variable like in the user-level Perl scripts.
