Adding Accounts

To add a new user account on the system, the useradd utility is typically used. On some distributions, such as Ubuntu, a script called adduser is used when adding users to the system, but it invokes the useradd program to handle the actual task.

The adding accounts process actually involves several players besides the core useradd program. Figure 13.3 depicts the process.

FIGURE 13.3 Adding a user account

You can see in Figure 13.3 that there are several team players involved in the account creation process. Notice that the /etc/skel directory is bolded. This is because, depending upon the other configuration files, it may not be used in the process. The same goes for the /home/ userid directory. It may not be created or it may have an alternative name, depending upon the system's account creation configuration. You'll learn more about these directories shortly.

Before we jump into the useradd utility details, let's look at the two files and the directory involved in the creation side of the process.
