Subject: [Launchpad-users] how to recover /etc/shadow file from single
usermode
Hi,
I have forgotten the root passwod in my system. I have installed ubuntu
9.04. The /etc/shadow file also been corrupted. Now please let me know
how I can recover the file from single user mode?
Ubuntu does not have a root user, but a root group. Any user that is on
the
root group is able to login as root (this means, having to use sudo or
any
other thrust level elevation tool/command.)
That's not true. If there wasn't a root user, there would be nothing
to sudo to. All you need to be able to log in as root without using
sudo is to set the password for the root user.
Saikat, you can get a shell without having to enter the root password
by editing the grub config at boot time.
1. At the grub screen, hit 'e' to edit the config.
2. Use the arrow keys to move to the line that starts with "kernel".
3. Hit 'e' to edit it.
4. Append " init=/bin/bash" to the line.
5. Hit Enter.
6. Hit 'b' to boot.

Thanks for clearing that, I thought the root user had been moved into a
group in Ubuntu as I have seen the root group, but not the user. Perhaps I
did not aim my eyes in correctly in order to see that. It was strange to me,
as in many other distros I knew about the root user, but as I did not saw it
on Ubuntu...
