Hi
I'm pretty new to linux (working on fedora) and managed to mess something up, hopefully u can help me to undo it!

While logged in as root I added root to the named group with the command:
usermod -G named root

What i didnt realise was that this command also takes root out of every group except named and root.

I had a 2 month old backup of the passwd file, I thought this would revert the groups back to what they had been 2 months ago but when I tried it root is still just a member of named and root.

I want root to be a member of all the groups it was a member of before I executed this command.
Any help would be appreciated..

Hi.

Unless you've got a backup of /etc/group , you're out of luck. If you do happen to have a backup, just replace the root line in /etc/group with the line from the backup.

Do read the manual

#man usermod

Thanks Dave, that worked great.
