Adding a User
If you are doing this as root, don't use the 'sudo' command.
To add a user to the system:
- Issue the useradd command to create a locked user account:
sudo useradd <username>
- Unlock the account by issuing the passwd command to assign a password and set password aging guidelines:
sudo passwd <username>
If you get the following error:
bash: useradd: command not found
Try
sudo /sbin/useradd <username>
Or
sudo /usr/sbin/useradd <username>
Examples
See what groups the user is in:<br />
id -nG {user-name} <br />
Add user and specify home directory while adding to groups:<br />
sudo useradd -d /home/testuser -m testuser -G adm,dialout,cdrom,plugdev,lpadmin,sambashare,admin <br />
Add user to a group: <br />
sudo useradd -a -G admin testuser <br />
To modify (or remove from) group membership, just specify explicitly: <br />
sudo useradd -G adm,dialout,cdrom,plugdev testuser <br />
