Access the system library folder rather than the user library folder with Terminal

Question

I am trying to chmod a folder in the library of my Mac but I can only get to the folders below the user level.

I need Library/WebServer/Documents/..., but I can only get to user/me/..., etc.

Does anyone know what I need to do?

Answer 1

Even administrator users should use sudo -s or sudo chmod /Library/Webserver since the default group structure on OS X is to protect system resources from modification without the logging the privilege escalation. You will need to be an administrator of the mac to use sudo, so you can always su to an existing admin account first before using sudo.
