-Slackware Linux inherits a strong multi-user tradition from its UNIX
-inspiration. This means that multiple people may use the system at
-once, but it also means that each of these people may have different
-permissions. This allows users to prevent others from modifying their
-files, or lets system administrators explicitly define what users can
-and cannot do on the system. Moreover, users need not be actual people
-at all. In fact, Slackware includes several dozen pre-defined user
-and group accounts that are not typically used by regular users. Rather
-these accounts allow the system administrator to segment the system for
-security reasons. We'll see how that's done in the next chapter on
-filesystem permissions.

 <para>
-The easiest way to add new users in Slackware is through the use of our
-very fine <application>adduser</application> shell script.
-<application>adduser</application> will prompt you to enter the details
-of the new user you wish to creature and step you through the process
-quickly and easily. It will even create a password for the new user.
-</para>
-
-<screen><prompt>darkstar:~# </prompt><userinput>adduser</userinput>
-
-Login name for new user []: <userinput>david</userinput>
-
-User ID ('UID') [ defaults to next available ]: 
-
-Initial group [ users ]: 
-Additional UNIX groups:
-
-Users can belong to additional UNIX groups on the system.
-For local users using graphical desktop login managers such
-as XDM/KDM, users may need to be members of additional groups
-to access the full functionality of removable media devices.
-
-* Security implications *
-Please be aware that by adding users to additional groups may
-potentially give access to the removable media of other users.
-
-If you are creating a new user for remote shell access only,
-users do not need to belong to any additional groups as standard,
-so you may press ENTER at the next prompt.
-
-Press ENTER to continue without adding any additional groups
-Or press the UP arrow to add/select/edit additional groups

-The addition of optional groups needs a little explaining. Every user
-in Slackware has a single group that it is always a member of. By
-default, this is the "users" group. However, users can belong to more
-than one group at a time and will inherit all the permissions of every
-group they belong to. Typical desktop users will need to add several
-group memberships in order to do things like play sound or access
-removeable media like cdroms or USB flash drives. You can simply press
-the up arrow key at this section and a list of default groups for
-desktop users will magically appear. You can of course, add to or
-remove groups from this listing.

-Now that we've demonstrated how to use the interactive
-<application>adduser</application> program, lets look at some powerful
-non-interactive tools that you may wish to use. The first is
-<application>useradd</application>(8).
-<application>useradd</application> is a little less friendly, but much
-faster for creating users in batches. This makes it ideal for use in
-shell scripts. In fact, <application>adduser</application> is just such
-a shell script and uses <application>useradd</application> for most of
-the heavy lifting. <application>useradd</application> has many options
-and we can't explain them all here, so refer to its man page for the
-complete details. Now, let's make a new user.
-</para>
-
-<screen><prompt>darkstar:~# </prompt><userinput>useradd -d /data/home/alan -s /bin/bash -g users -G audio,cdrom,floppy,plugdev,video alan</userinput>
-</screen>
-
-<para>
-Here I have added the user "alan". I specified the user's home
-directory as <filename>/data/home/alan</filename> and used
-<application>bash</application> as my shell. Also, I specified my
-default group as "users" and added myself to a number of useful groups
-for dekstop use.  You'll note that <application>useradd</application>
-does not do any prompting like <application>adduser</application>.
-Unless you want to accept the defaults for everything, you'll need to
-tell <application>useradd</application> what to do.
-</para>
-
-<para>
-Now that we know how to add users, we should learn how to add groups.
-As you might have guessed, the command for doing this is
-<application>groupadd</application>(8).
-<application>groupadd</application> works in the same way as
-<application>useradd</application>, but with far fewer options. The
-following command adds the group "slackers" to the system.
-</para>
-
-<screen><prompt>darkstar:~# </prompt><userinput>groupadd slackers</userinput>
-</screen>
-
-<para>
-Deleting users and groups is easy as well. Simply run the
-<application>userdel</application>(8) and
-<application>groupdel</application>(8) commands. By default,
-<application>userdel</application> will leave the user's home directory
-on the system. You can remove this with the <arg>-r</arg> argument.

-<title>Other User and Group Tools</title>
-
-<para>
-Several other tools exist for managing users and groups. Perhaps the
-most important one is <application>passwd</application>(1). This
-command changes a user account's password. Normal users may change
-their own passwords only, but root can change anyone's password. Also,
-root can lock a user account with the <arg>-l</arg> argument. This
-doesn't actually shutout the account, but instead changes the user's
-encrypted password to a value that can't be matched.
-</para>
-
-<para>
-Another useful tool is <application>chsh</application>(1) which changes a
-user's default shell. Like <application>passwd</application>, normal
-users can only change their own shell, but the root user can change
-anyone's.
-</para>
-
-<para>
-The last tool we're going to discuss is
-<application>chfn</application>(1). This is used to enter identifying
-information on the user such as his phone number and real name. This
-information is stored in the <filename>passwd</filename>(5) file and
-retrieved using <application>finger</application>(1).
-</para>

-<title>Managing Users and Groups Manually</title>
-
-<para>
-Like most things in Slackware Linux, users and groups are stored in
-plain-text files. This means that you can edit all the details of a
-user, or even create a new user or group simply by editing these files
-and doing a few other tasks like creating the user's home directory. Of
-course, after you see how this is done you'll appreciate just how
-simple the included tools make this task.
-</para>
-
-<para>
-Our first stop is the <filename>/etc/passwd</filename> file. Here, all
-the information about a user is stored, except for (oddly enough) the
-user's password. The reason for this is rather simple.
-<filename>/etc/passwd</filename> must be readable by all users on the
-system, so you wouldn't want passwords stored there, even if they are
-encrypted. Let's take a quick look at my entry in this file.
-</para>
-
-<screen>
-alan:x:1000:100:,,,:/home/alan:/bin/bash
-</screen>
-
-<para>
-Each line in this file contains a number of fields seperated by a
-colon. They are, from left to right: username, password, UID, GUID, a
-comment field, home directory, and shell. You'll notice that the
-password field for every entry is an <keycap>x</keycap>. That is
-because Slackware uses shadow passwords, so the actual encrypted
-password is stored in <filename>/etc/shadow</filename>. Let's take a
-look there.
-</para>
-
-<screen>
-alan:$1$HlR?M3fkL@oeJmsdLfhsLFM*4dflPh8:14197:0:99999:7:::
-</screen>
-
-<para>
-The <filename>shadow</filename> file contains more than just the
-encrypted password as you'll notice. The fields here, again from left
-to right, are: username, encrypted password, last day the password was
-changed, days before the password may be changed again, how many days
-before the password expires, days that the account will be disabled
-after expiring, when the account was disabled, and a reserved field.
-You may notice on some accounts that the various "days" fields often
-include very large numbers. The reason for this is that Slackware
-counts time from the "Epoch" which is January 1, 1970 for historical
-reasons.
-</para>
-
-<para>
-To create a new user account, you'll just need to open these files
-using <application>vipw</application>(8). This will open
-<filename>/etc/passwd</filename> in the editor
-defined by your VISUAL variable or your EDITOR variable if VISUAL isn't
-defined. If neither is present, it will fall back to
-<application>vi</application> by default. If you pass the <arg>-s</arg>
-argument, it will open <filename>/etc/shadow</filename> instead. It's
-important to use <application>vipw</application> instead of using any
-other editor, because <application>vipw</application> will lock the
-file and prevent other programs from editing it right underneath your feet.
-</para>
+<title>Commandline Printing Tools</title>
 
 <para>
-That isn't all you'll need to do however; you must also create the
-user's home directory and change the user's password using
-<application>passwd</application>.
