Hello i just switched from osx and am using ubuntu 10.10. im trying to setup a local server and am having trouble moving files into the localhost folder (/var/www) i know i need to change permissions of the folder to be able to place files in it. i was told to use chmod, but i dont know what that is or how to use it, if anyone can help me by providing a step by step to making that folder writable i would really appreciate it, thank you in advance
