[SOLVED] What's the command to add these groups to user account?

What's the single command to add these groups to user account?

Code:

users floppy audio video cdrom plugdev power netdev

Suppose user account "myuser" is already created with only "users" group.

Is it ok?

Code:

usermod -G floppy audio video cdrom plugdev power netdev <useraccount>

pixellany · 01-29-2010, 07:18 AM

usermod -a -G

Look at the man page for details

You need the -a flag

Did you looked at
man usermod ?

mRgOBLIN · 01-29-2010, 07:21 AM

Code:

usermod -G users,floppy,audio,video,cdrom,plugdev,power,netdev myuser

Reinstalled system.
man usermod

Code:

bash: man: command not found

Missing some packages.

mRgOBLIN · 01-29-2010, 07:28 AM

Don't use usermod, I believe it may be dangerous.

Instead do:

Code:

for group in users floppy audio video cdrom plugdev power netdev; do gpasswd -a $USER $group; done

Then make sure to reload messagebus:

Code:

/etc/rc.d/rc.messagebus reload

Thanks for your suggestion.
I will go for gpasswd -a.

I would use gpasswd also. Just see "man gpasswd" for the details. The syntax is:

Code:

gpasswd -a user group

where user is the user name you want to modify, and group is the group(s) you want to add the user to.

you can add an user to a predefined set (that nearly match yours) also when you create the account with adduser.
after selecting user's main group ("users" by default) you are presented a prompt in which you have to input additional groups

Code:

Additional UNIX groups:

Users can belong to additional UNIX groups on the system.
For local users using graphical desktop login managers such
as XDM/KDM, users may need to be members of additional groups
to access the full functionality of removable media devices.

* Security implications *
Please be aware that by adding users to additional groups may
potentially give access to the removable media of other users.

If you are creating a new user for remote shell access only,
users do not need to belong to any additional groups as standard,
so you may press ENTER at the next prompt.

Press ENTER to continue without adding any additional groups
Or press the UP arrow to add/select/edit additional groups
:

if you press the up arrow the prompt is filled with a set of default group for having a comfortable slackware desktop experience.

I'd just use vigr(8) and add them to /etc/group manually. :-)

Me too. My memory stinks, so I'm never able to remember those commands, and it's faster for me to just edit with vigr, then to read one or two manpages.
