ADDING_USER(8)          FreeBSD System Manager's Manual         ADDING_USER(8)

     adding_user - procedure for adding new users

     A new user must choose a login name, which must not already appear in
     /etc/passwd or /etc/mail/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 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,

     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/share/skel
     contains skeletal definitions of such files.  New users should be given
     copies of these files which, for instance, use tset(1) automatically at
     each login.

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

     chpass(1), finger(1), passwd(1), aliases(5), passwd(5), adduser(8),
     pwd_mkdb(8), vipw(8)
