    NAME
         adduser - procedure for adding new users

    DESCRIPTION
         A new user must choose a login name, which must not already
         appear in /etc/passwdor /etc/aliases.  It must also not
         begin with the hyphen (``-'') character.  It is strongly
         recommended that it be all lower-case, and not contain the
         dot (``.'') character, as that tends to confuse mailers.  An
         account can be added by editing a line into the passwd file;
         this must be done with the password file locked e.g. by
         using chpass(1) or vipw(8).

         A new user is given a group and user id.  Login's and user
         id's should be unique across the system, and often across a
         group of systems, since they are used to control file
         access.  Typically, users working on similar projects will
         be put in the same groups.  At the University of California,
         Berkeley, we have groups for system staff, faculty, graduate
         students, and special groups for large projects.

         A skeletal account for a new user "ernie" might look like:

    	  ernie::25:30::0:0:Ernie Kovacs,508 Evans
    	  Hall,x7925,642-8202:/a/users/ernie:/bin/csh

         For a description of each of these fields, see passwd(5).

         It is useful to give new users some help in getting started,
         supplying them with a few skeletal files such as .profile if
         they use "/bin/sh", or .cshrc and .login if they use
         "/bin/csh".  The directory "/usr/skel" contains skeletal
         definitions of such files.  New users should be given copies
         of these files which, for instance, use tset(1) automati-
         cally at each login.

    FILES
         /etc/master.passwd  user database
         /usr/skel		 skeletal login directory

    SEE ALSO
         chpass(1), finger(1), passwd(1), aliases(5), passwd(5),
         mkpasswd(8), vipw(8)

    BUGS
         User information should (and eventually will) be stored
         elsewhere.
