.Os
.Sh NAME
.Nm userdel
.Nd remove a user from the system
.Sh SYNOPSIS
.Nm ""
.Fl D
.Op Fl p Ar preserve-value
.Nm ""
.Op Fl prv
.Ar user
.Sh DESCRIPTION
The
.Nm
utility removes a user from the system, optionally
removing that user's home diretory and any subdirectories.
.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,
.Fl D
will show the current defaults which will be used by the
.Nm
utility.  Additionally, if running as root and the
.Pa /etc/usermgmt.conf 
file does not exist, it is created using the default values.
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
The following command line options are recognised:
.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.
.Sh FILES
