changing a users group name?

[Huggy]

when I made a user I *ucked up I had made a user named darrell and in a group called darrell I need to change that to group users
I know its the (I think)
chown [option] owner group
but it don't work what I'm not doing?
please give some insite I'm trying to really learn this stuff. :eek:

/usr/sbin/usermod -g users darrell

for more information run
/usr/sbin/usermod -h
or
man usermod

To change a user's primary group, edit /etc/passwd and change the user's entry. The second number is for group ID. Cross-reference with /etc/group to get a list of group IDs.

You can add users to multiple groups. Edit /etc/group to do so.

To change both user and group ownerships on a file:

chown username.groupname filename

OR

chown userid.groupid filename

To change just the group ownership of a file, use the chgrp command.

this is what I have in /etc/psswd
darrell:x:500:100:darrell lastname: bla bla
larry:x:501:100:bla bla bla
guest:x:502:100::bla bla bla bl

and this for /etc/group
users:x:100
darrell:x:500

So what numbers am I changing?
you said the 2nd was the group ID and to look up what it was in the etc/group/ well the only same number there is 100 :confused:

If the second numbers for all the users is 100, then they're all in the Users group. Is there something that makes you think otherwise?
