How do I edit my sources.list file?

[hypersonic5]

Ubuntu newbie here. I want to add a bunch of new repositories to Ubuntu but I can't seem to figure out how to edit the file itself. I can't log in as root in Ubuntu therefore I can't directly edit it and save like any other file. Can someone please show me how to do this? I'm sorry if it has been asked before, but I searched for sources.list and came up with nothing.

Thanks in advance.

You can either fire up synaptic and go to "setting -> repositories" or edit the sources.list file by typing

$ sudo gedit /etc/apt/sources.list

Remember that Ubuntu does everything with "sudo" - that's your access to the root account

hello
/etc/apt/sources.list
if you have mc installed (sudo mc) then F4 you can easy pass or copy inside
or more ubuntu way (maybe : sudo gedit /etc/apt/sources.list)
