        !             9: .SH NAME
        !            10: adduser \- procedure for adding new users
        !            11: .SH DESCRIPTION
        !            12: A new user must choose a login name, which must not already appear in
        !            13: \fI/etc/passwd\fP or \fI/usr/lib/aliases\fP.  It must also not begin with
        !            14: the hyphen (``-'') character.  An account can be added by editing a line
        !            15: into the passwd file; this must be done with the password file locked
        !            16: e.g. by using
        !            17: .IR vipw (8).
        !            18: .PP
        !            19: A new user is given a group and user id.
        !            20: User id's should be distinct across a system, since they
        !            21: are used to control access to files.
        !            22: Typically, users working on
        !            23: similar projects will be put in the same group.  Thus at UCB we have
        !            24: groups for system staff, faculty, graduate students, and a few special
        !            25: groups for large projects.  System staff is group \*(lq10\*(rq for historical
        !            26: reasons, and the super-user is in this group.
        !            27: .PP
        !            28: A skeletal account for a new user \*(lqernie\*(rq would look like:
        !            29: .IP
        !            30: ernie::235:20:& Kovacs,508E,7925,6428202:/mnt/grad/ernie:/bin/csh
        !            31: .PP
        !            32: The first field is the login name \*(lqernie\*(rq.  The next field is the
        !            33: encrypted password which is not given and must be initialized using
        !            34: .IR passwd (1).
        !            35: The next two fields are the user and group id's.
        !            36: Traditionally, users in group 20 are graduate students and have account
        !            37: names with numbers in the 200's.
        !            38: The next field gives information about ernie's real name, office and office
        !            39: phone and home phone.
        !            40: This information is used by the
        !            41: .IR finger (1)
        !            42: program.
        !            43: From this information we can tell that ernie's real name is
        !            44: \*(lqErnie Kovacs\*(rq (the & here serves to repeat \*(lqernie\*(rq
        !            45: with appropriate capitalization), that his office is 508 Evans Hall,
        !            46: his extension is x2-7925, and this his home phone number is 642-8202.
        !            47: You can modify the
        !            48: .IR finger (1)
        !            49: program if necessary to allow different information to be encoded in
        !            50: this field.  The UCB version of finger knows several things particular
        !            51: to Berkeley \- that phone extensions start \*(lq2\-\*(rq, that offices ending
        !            52: in \*(lqE\*(rq are in Evans Hall and that offices ending in \*(lqC\*(rq are
        !            53: in Cory Hall. The 
        !            54: .IR chfn (1)
        !            55: program allows users to change this information.
        !            56: .PP
        !            57: The final two fields give a login directory and a login shell name.
        !            58: Traditionally, user files live on a file system different from /usr.
        !            59: Typically the user file systems are mounted on a directories in the root
        !            60: named sequentially starting from from the beginning of the alphabet,
        !            61: eg /a, /b, /c, etc.
        !            62: On each such file system there are subdirectories there for each group
        !            63: of users, i.e.: \*(lq/a/staff\*(rq and \*(lq/b/prof\*(rq.
        !            64: This is not strictly necessary but keeps the number of files in the
        !            65: top level directories reasonably small.
        !            66: .PP
        !            67: The login shell will default to \*(lq/bin/sh\*(rq if none is given.
        !            68: Most users at Berkeley choose \*(lq/bin/csh\*(rq so this is usually
        !            69: specified here. The 
        !            70: .IR chsh (1)
        !            71: program allows users to change their login shell to one of the
        !            72: shells in the approved list given in /etc/shells.
        !            73: .PP
        !            74: It is useful to give new users some help in getting started, supplying
        !            75: them with a few skeletal files such as
        !            76: .I \&.profile
        !            77: if they use \*(lq/bin/sh\*(rq, or
        !            78: .I \&.cshrc
        !            79: and
        !            80: .I \&.login
        !            81: if they use \*(lq/bin/csh\*(rq.
        !            82: The directory
        !            83: \*(lq/usr/skel\*(rq contains skeletal definitions of such files.
        !            84: New users should be given copies of these files which, for instance,
        !            85: arrange to use
        !            86: .IR tset (1)
        !            87: automatically at each login.
        !            88: .SH FILES

        !            95: .SH BUGS
        !            96: User information should be stored in its own data base separate from
        !            97: the password file.
