.TH ADDUSER 8
.SH NAME
adduser \- procedure for adding new users
.SH DESCRIPTION
A new user must choose a login name, which must not already appear in
.I /etc/passwd.
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
.IR vipw (8).
.PP
A new user is given a group and user id.
User id's should be distinct across a system, since they
are used to control access to files.
Typically, users working on
similar projects will be put in the same group.
System staff is group \*(lq10\*(rq for historical
reasons, and the super-user is in this group.
.PP
A skeletal account for a new user \*(lqernie\*(rq would look like:
.IP
ernie::235:20:& Kovacs,508E,7925,6428202:/mnt/grad/ernie:/bin/csh
.PP
The first field is the login name \*(lqernie\*(rq.  The next field is the
encrypted password which is not given and must be initialized using
.IR passwd (1).
The next two fields are the user and group id's.
The next field gives information about ernie's real name, office and office
phone and home phone.
This information is used by the
.IR finger (1)
program.
From this information we can tell that ernie's real name is
\*(lqErnie Kovacs\*(rq (the & here serves to repeat \*(lqernie\*(rq
with appropriate capitalization), that his office is 508 Evans Hall,
his extension is x2-7925, and this his home phone number is 642-8202.
You can modify the
.IR finger (1)
program if necessary to allow different information to be encoded in
this field.
.PP
The final two fields give a login directory and a login shell name.
The login shell will default to \*(lq/bin/sh\*(rq if none is given.
Most users choose \*(lq/bin/csh\*(rq so this is usually
specified here.
.PP
It is useful to give new users some help in getting started, supplying
them with a few skeletal files such as
.I \&.profile
if they use \*(lq/bin/sh\*(rq, or
.I \&.cshrc
and
.I \&.login
if they use \*(lq/bin/csh\*(rq.
The directory
\*(lq/usr/skel\*(rq contains skeletal definitions of such files.
New users should be given copies of these files which, for instance,
arrange to use
.IR tset (1)
automatically at each login.
.SH FILES
.ta 2i
/etc/passwd	password file
.br
/usr/skel	skeletal login directory

.SH BUGS
User information should be stored in its own data base separate from
the password file.
