You have two approaches when creating users from a command-line environment: you can use the useradd command, or you can add users to the relevant configuration files by manually editing these files. Although this second approach editing the configuration files may be useful in an environment in which users are added from a custom-made shell script, it generally is not recommended. The reason for this is probably obvious: an error in the main user configuration files might make it impossible for every user to log in to the server. In this section, I ll discuss how to manage users from the command line using useradd and other related commands such as usermod and userdel. You can edit related configuration files to make creating users easier.

If you want to add users from the command line, useradd is just the ticket. And the other commands for user management are just as convenient: useradd: Adds users to the local authentication system usermod: Modifies properties for users userdel: Deletes users properly from a system passwd: Modifies passwords for users Using useradd is simple. In its easiest form, it just takes the name of a user as its argument; thus, useradd zeina creates a user called zeina to the system. However, you better use the option -m as well, because, if you don t, that user will be without a home directory. In most cases, a user should have a home directory because it allows that person to store files somewhere. Unfortunately, if you create a user without a home directory, there s really no easy way to correct this problem later (but see the following tip for the not-so-easy way).

mkdir /home/zeina to make the directory itself. Then use cd /etc/skel to activate the directory that contains all files that normally need to be present in a user s home directory. Use tar cv . | tar xvC /home/zeina to copy all files including hidden files from this directory to the user s home directory. Next, use chown -R zeina.users /home/zeina to set proper file ownership for all these files. You ve now created a home directory, but wouldn t it have been easier just to use -m

You have a few options with the useradd command. If an option isn t specified, useradd will read its configuration file in /etc/default/useradd, where it finds some default values such as what groups the user should become a member of and where to create the user s home directory. But let s have a look at the most important options, which are listed next. (For a complete list of available options, use man useradd or useradd --help for a summary.) -c comment: Allows you to enter a comment field to the user. Information set this way can be requested with the finger command, and this comment field typically is used for the user s name. -e date: Sets the expiration date for the user. Use this option to automatically disable the user s account on the specified date. This can be entered in the YYYY-MM-DD format or as the number of days since January 1, 1970. You ll probably prefer to specify the date. -G groups: Makes the user a member of some additional groups. By default, the user becomes a member of only those groups listed in /etc/default/useradd. -g gid: Sets the primary group of a user (see the section Group Membership later in this chapter for more details). -m: Creates a home directory automatically.
