kk, I am guilty of easily just booting up in Kde's gui, start/system
settings/users and groups but then also I'd rather do it from the bash
console.
after googling around a good bit I am still not exactly sure of the
proper way to do this.
I want to add a user to another group w/out removing the groups the user
already belongs to.
in man usermod:
-G group,[...]
A list of supplementary groups which the user is also
a member of. Each group is separated from the next by a comma, with no
intervening whitespace. The groups are subject to the
same restrictions as the group given with the -g option. If the
user is currently a member of a group which is not
listed, the user will be removed from the group. This behaviour can
be changed via -a option, which appends user to the current
supplementary group list.
ok...I kinda get this but unclear of the exact format and I am super
fearful of ripping up my userbase.
Here is what I think it should be:
# usermod <user> -a -G <group>
where the user's name is say..."pete" and I want him to be added to the
group "tech":
# usermod pete -a -G tech
Say pete is already in groups ummm, sales,admin, and help. After
administering the above command, would pete still be in sales,
admin,help, and now tech? I am interested in the simplest, correct way
to do this.
thx,
John Rose
