If ya wanna get into root. Use the command

sudo su

then type your password and hit enter.

EDITL: If I was you. I'd be sure to type exit when you are done.

Try

su -

(password)
You do not need to specify root as the user.
Keep in mind Ubuntu disables root logins and uses sudo instead. If you want to use root then you need to set it up yourself.

Roky, I'm not preaching at you bro but I think you should use the hyphen like I showed, typing "su" will prompt you for the root password and if given correctly you get root privileges. Typing "su -" and giving the correct password gives you root's privileges and environment.

You know me. I'm still learning. I'm open to any preaching.


EDIT wrote it down in my Useful commands document TBob.

There are a handful of ways to work in Ubuntu with a root shell without "enabling" the root user. Although I was originally annoyed by Ubuntu disabling it I've since come to appreciate the fact that I don't find myself running shells as root when 95%+ of my commands don't require root, and I've yet to accidentally run something as root

The following will all more or less achieve a root shell

sudo -i
sudo bash
sudo su -

Mike, you're dead right about the hyphen adding root's environment, but as far as I know regular users have the same $PATH as root in Ubuntu, so say fdisk will work instead of requiring /sbin/fdisk

HIya Bigtom!
Thanks, this is very useful to know. I have used Ubuntu but it wasn't my machine, I guess I really should brush up on my distro slutting skills.

dude, open your terminal and do these:
sudo passwd root rootpass
sudo passwd -u root

sudo will ask for your user password. use that. the rootpass set to whatever you want fory our password, and the -u root part unlocks the account.
