Create New User on Ubuntu 9.10 Server - Step-by-Step Guide

Adding a New User on Ubuntu Server

The process of establishing a new user account on an Ubuntu server is straightforward. It can be accomplished by elevating your shell privileges to root access using sudo, or by executing a specific command.

The 'adduser' Command

To create a new user, utilize the following command: adduser username. This command initiates the user creation process.

The system will then display output similar to the following, confirming the steps taken:

root@ubuntugeek910:~# adduser testuserAdding user `testuser' ...Adding new group `testuser' (1001) ...Adding new user `testuser' (1001) with group `testuser' ...Creating home directory `/home/testuser' ...Copying files from `/etc/skel' ...

This indicates that a new group and user have been added, a home directory created, and default configuration files copied.
