.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility modifies user login information on the system.
|
|
.Pp
|
|
Default values are taken from the information provided in the
|
|
.Pa /etc/usermgmt.conf
|
|
file, which, if running as root, is created using the built-in defaults if
|
|
it does not exist.
|
|
.Pp
|
|
After setting any defaults, and then reading values from
|
|
.Pa /etc/usermgmt.conf ,
|
|
the following command line options are processed:
|
|
.Bl -tag -width Ds
|
|
.It Fl C Ar yes/no
|
|
Enable user accounts to be temporary locked/closed.
|
|
The
|
|
.Ar yes/no
|
|
operand can be given as
|
|
.Dq Ar yes
|
|
to lock the account or
|
|
.Dq Ar no
|
|
to unlock the account.
|
|
.It Fl c Ar comment
|
|
Set the comment field (also, for historical reasons known as the
|
|
GECOS field) for the user.
|
|
The comment field will typically include
|
|
the user's full name and, perhaps, contact information for the user.
|
|
.It Fl d Ar home-directory
|
|
Set the home directory to
|
|
.Ar home-directory
|
|
without populating it; if the
|
|
.Fl m
|
|
option is specified, tries to move the old home directory to
|
|
.Ar home-directory .
|
|
.It Fl e Ar expiry-time
|
|
Set the time at which the account expires.
|
|
This can be used to implement password aging.
|
|
It should be entered in the form
|
|
.Dq month day year ,
|
|
where month is the month name (the first three characters are
|
|
sufficient), day is the day of the month, and year is the year.
|
|
Time in seconds since the epoch (UTC) is also valid.
|
|
A value of 0 can be used to disable this feature.
|
|
This value can be preset for all users using the
|
|
.Ar expire
|
|
field in the
|
|
.Pa /etc/usermgmt.conf
|
|
file.
|
|
See
|
|
.Xr usermgmt.conf 5
|
|
for more details.
|
|
.It Fl F
|
|
Force the user to change their password upon next login.
|
|
.It Fl f Ar inactive-time
|
|
Set the time at which the password expires.
|

option.
|
|
.It Fl G Ar secondary-group
|
|
Specify a secondary group to which the user will be added in the

|
|
.It Fl g Ar gid | name | Li =uid
|
|
Give the group name or identifier to be used for the user's primary group.
|
|
If this is
|
|
.Ql =uid ,
|
|
then a uid and gid will be picked which are both unique
|
|
and the same, and a line will be added to
|
|
.Pa /etc/group
|
|
to describe the new group.
|
|
This value can be preset for all users by using the
|
|
.Ar gid
|
|

|
argument of the
|
|
.Fl l
|
