.Sh SYNOPSIS
|
|
.Nm ""

|

|

|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility removes a user from the system, optionally
|
|
removing that user's home diretory and any subdirectories.
|
|
.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
|
|
The first form of the command shown above (utilising the
|
|
.Fl D
|
|
option) sets and displays the defaults for the
|
|
.Nm
|
|
utility.
|
|
.Bl -tag -width Ds
|
|
.It Fl D
|
|
without any further options,
|
|
.Fl 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,
|
|
.Fl D
|
|
will set the default to be the new value.
|
|
.It Fl p Ar preserve-value
|
|
sets the preservation value. If this value is one of
|
|
.Ql true ,
|
|
.Ql yes ,
|
|
or a non-zero number, then the user login information will be preserved.
|
|
.El
|
|
.Pp
|
|
In the second form of the command,
|
|
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 p
|
|
preserve the user information in the password file,
|
|
but do not allow the user to login, by switching the
|
|
password to an
|
|
.Dq impossible
|
|
one, and by setting the
|
|
user's shell to the
|
|
.Xr nologin 8
|
|
program. This option can be helpful in preserving a user's
|
|
files for later use by members of that person's
|
|
group after the user has moved on.
|
|
This value can also be set in the
|
|
.Pa /etc/usermgmt.conf
|
|
file, using the
|
|
.Ql preserve
|
|
field. If the field has any of the values
|
|
.Ql true ,
|
|
.Ql yes ,
|
|
or a non-zero number, then user information preservation will take place.
|
|
.It Fl r
|
|
remove the user's home directory, any subdirectories,
|
|
and any files and other entries in them.
|
|
.It Fl v
|
|
perform any actions in a verbose manner.
|
|
.El
|
|
.Pp
|
|
Once the information has been verified,
|
|
.Nm
|
|
uses
|
|
.Xr pwd_mkdb 8
|
|
to update the user database. This is run in the background, and,
|
|
at very large sites could take several minutes. Until this update
|
|
is completed, the password file is unavailable for other updates
|
|
and the new information is not available to programs.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility exits 0 on success, and \*[Gt]0 if an error occurs.
