how to edit files owned by root?
I need to edit some system file but I can't save them after the modifications because "I'm not the owner" and the system tell me averytime that "I've not the correct permission to save the file".
I suppose to have to log myself as root user to be able to edit and save system files, but I don't know how to do it.
someone could help me? (I use ubuntu 7.10)
