How to I add my username to the sudoers file?
On my ubuntu desktop, the sudoer file has only root.
so basically, I will just need to adduser to sudo file system. And I need to access to single user mode.
I know the easiest way to to just select recovery mode in grub by hold down left Shift when booting. Then Drop to root shell prompt.
But it is ready-only file system. I need to write myself to the file.
I know I have to select remount first, but where is it?
and any other way to add myself to sudo?
