Removed myself from groups that I need (Ubuntu)

08-16-2007, 06:40 AM

Hi to all,

I am in bad trouble; getting to know an OS is trying things... I tried this morning things in the "Users & Groups", and removed myself from groups that I - obviously - need... I don't even see the "Users & Groups" any longer in the system maintenance menu.

I still have root access through the console, but I wasn't able to find out how to get myself back in the groups that I need...

If anyone knows... please help me out of this... Life is a bit "limited" now!

Hi Richard,
To see what groups you are in open a terminal and run the command

Code:

sudo more /etc/group

This will display all groups on your computer..... When you can see the groups that you whish to be a member of run this command.

Code:

sudo usermod -g <group_name> <user_name>

e.g.

Code:

sudo usermod -g admin mike

Hope this helps

Hi Mike,

Two important commands learned today: the first one to list the groups and their members (which was a few times very useful), and the "usermod" command; although I used it a bit different:

Code:

sudo usermod -a -G admin richard

Which did the trick; log off, log on and all is back to normal!

The usermod command as given in your reply didn't seem to give any results, the list command still showed the 'admin' group empty.

Another important lesson learned: Make sure you have an 'admin' backup user when 'fiddling around'!!!

Thank you very much for the assistance!!!

The file only shows your secondary groups when added through the GUI, this file "/etc/group" can also be edited directly by entering the the user at the end of the line for each group you want that user to becom a member of.

Hi Mike,

Thanks for the suggestion about the 'groups' file, I'll keep that in mind.

I will join the Ubuntu forum tonight, I am now in a kind of a hurry!

Hey, I like the signature, may snatch it
