to the Ubuntu 20.04 operating system:$ sudo adduser lubos Adding user `lubos' ... Adding new group `lubos' (1001) ... Adding new user `lubos' (1001) with group `lubos' ... Creating home directory `/home/lubos' ... Copying files from `/etc/skel' ... Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully Changing the user information for lubos Enter the new value, or press ENTER for the default Full Name []: Room Number []: Work Phone []: Home Phone []: Other []: Is the information correct? [Y/n] y
The user information is optional as the only required input is the new user password.
- (optional) Depending on your system and the environment you might need to add a user to a specific group. For example, the following command will add a user
lubos
to the groupcdrom
:$ sudo usermod -aG cdrom lubos

To list all available system groups enter thecat /etc/group
command into your terminal window. - (optional) Lastly, retrieve user and group information to confirm the successful user creation:
