This option forces the removal of the user account, even if the

user is still

logged in. It also forces <command>userdel</command> to remove

the user's home directory and mail spool, even if another

user uses the same home directory or if the mail spool is not

|
owned by the specified user. If

remap='I'>yes</emphasis> in <filename>/etc/login.defs</filename>

<para>
|
|
<command>userdel</command> will not allow you to remove an account if
|
|
there are running processes which belong to this account. In that
|
|
case, you may have to kill those processes or lock the user's
|
|
password or account and remove the account later. The
|
|
<option>-f</option> option can force the deletion of this account.
|

</para>
|

<para>
|
|
You should manually check all file systems to ensure that no files
|
|
remain owned by this user.

</para>

|
<para>You may not remove any NIS attributes on a NIS client. This must

be performed on the NIS server.

<para>If <option>USERGROUPS_ENAB</option> is defined to <emphasis
|
|
remap='I'>yes</emphasis> in <filename>/etc/login.defs</filename>,
|
|
<command>userdel</command> will delete the group with the same name
|
|
as the user. To avoid inconsistencies in the passwd and group
|
|
databases, <command>userdel</command> will check that this group is
|
|
not used as a primary group for another user, and will just warn
|
|
without deleting the group otherwise. The <option>-f</option> option
|
|
can force the deletion of this group.
