.Sh DESCRIPTION
|
|
The
|
|
.Nm useradd
|
|
utility adds a user to the system, creating and
|
|
populating a home directory if necessary.
|
|
Any skeleton dot files will be provided
|
|
for the new user if they exist in the /etc/skel directory.
|
|
Default values for the base directory, the time of password expiry,
|
|
the skeleton directory,
|
|
seconds until password change, primary group, the range from which the uid will be
|
|
allocated,
|
|
and default login shell can be provided in the /etc/usermgmt.conf
|
|
file.
|
|
.Pp
|
|
The first format of the command shown above (utilising the -D option)
|
|
sets and displays the defaults for the
|
|
.Nm
|
|
utility.
|
|
.Bl -tag -width Ds
|
|
.It Fl D
|
|
without any further options, -D will show the current defaults which
|
|
will be used by the
|
|
.Nm
|
|
utility. Together with one of the options shown for the first version
|
|
of the command, -D will set the default to be the new value.
|
|
.It Fl b Ar base-dir
|
|
sets the base directory. This is the directory to which the user name
|
|
is added, which will be created if the -m option is specified and no
|
|
-d option is specified.
|
|
.It Fl e Ar expiry-time
|
|
sets the time at which the current password will expire for this user.
|
|
.It Fl f Ar inactive-secs
|
|
sets the number of seconds after which, if no login has occurred for
|
|
the user during that time, the login will be "locked".
|
|
.It Fl g Ar gid/groupname/=uid
|
|
sets the default group for any user added using the
|
|
.Nm
|
|
command.
|
|
.It Fl r Ar low..high
|
|
sets the low and high bounds of uid ranges for new users. A new user
|
|
can only be created if there are uids which can be assigned from one
|
|
of the free ranges.
|
|
.El
|
|
.Pp
|
|
In the second form of the command,
|
|
after setting any defaults, and then values from that file,
|
|
the command line options are processed:
|
|
.Bl -tag -width Ds
|
|
.It Fl G Ar secondary-group
|
|
is the secondary group to which the user will be added in
|
|
the /etc/group file.
|
|
.It Fl b Ar base-directory
|
|
is the base directory name, in which the user's new home
|
|
directory will be created, should the -m option be specified.
|
|
This value can be preset for all users
|
|
by using the
|
|
.Ar base_dir
|
|
field in the
|
|
.Xr /etc/usermgmt.conf
|
|
file - it has the format:
|
|
.Ar base_dir <path-to-base-dir> .
|
|
.It Fl c Ar comment
|
|
is the comment field (also, for historical reasons known as the
|
|
GECOS field) which will be added for the user, and typically will include
|
|
the username, and, perhaps, contact information for the user.
|
|
.It Fl d Ar home-directory
|
|
is the home directory which will be created and populated for the user,
|
|
should the -m option be specified.
|
|
.It Fl e Ar secs-to-expiry
|
|
provides the number of seconds since the epoch (UTC) at
|
|
which the current password change expire. This
|
|
can be used to implement password aging.
|
|
A value of
|
|
0 can be used to switch off this feature.
|
|
The default value for this field is 0.
|
|
See
|
|
.Xr passwd 5
|
|
for more details.
|
|
This value can be preset for all users
|
|
by using the
|
|
.Ar expire
|
|
field in the
|
|
.Xr /etc/usermgmt.conf
|
|
file - it has the format:
|
|
.Ar expire <secs-to-expiry> .
|
|
.It Fl g Ar gid/name/=uid
|
|
gives the group name or identifier to be used for the new user's primary group.
|
|
If this is
|
|
.Ar "-g=uid" ,
|
|
then a uid and gid will be picked which are both unique
|
|
and the same, and a line added to
|
|
.Ar /etc/group
|
|
to describe the new group.
|
|
This value can be preset for all users
|
|
by using the
|
|
.Ar gid
|
|
field in the
|
|
.Xr /etc/usermgmt.conf
|
|
file - it has the format:
|
|
.Ar group <groupname/groupid/=uid> .
|
|
.It Fl k Ar skeleton directory
|
|
gives the skeleton directory in which to find dot files
|
|
with which to populate the new user's home directory.
|
|
.It Fl m
|
|
create a new home directory for the new user.
|
|
.It Fl o
|
|
allow the new user to have a uid which is already in use for another user.
|
|
.It Fl p Ar password
|
|
specifies an already-encrypted password for the new user.
|
|
This password can then be changed by using the
|
|
.Xr chpass 1
|
|
utility.
|
|
This value can be preset for all users
|
|
by using the
|
|
.Ar password
|
|
field in the
|
|
.Xr /etc/usermgmt.conf
|
|
file - it has the format:
|
|
.Ar password <encrypted-password> .
|
|
.It Fl s Ar shell
|
|
specifies the login shell for the new user.
|
|
This value can be preset for all users
|
|
by using the
|
|
.Ar shell
|
|
field in the
|
|
.Xr /etc/usermgmt.conf
|
|
file - it has the format:
|
|
.Ar shell <login-shell> .
|
|
.It Fl u Ar uid
|
|
specifies a uid for the new user.
|
|
Boundaries for this value can be preset for all users
|
|
by using the
|
|
.Ar range
|
|
field in the
|
|
.Xr /etc/usermgmt.conf
|
|
file - they have the format:
|
|
.Ar range <starting-uid>..<ending-uid> .
|
|
.It Fl v
|
|
enables verbose mode - explain the commands as they are executed.
|
|
.El
|
