\fBuserdel\fR [选项] \fI登录\fR
.SH "描述"
.PP
The
\fBuserdel\fR
command modifies the system account files, deleting all entries that refer to the user name

.SH "选项"
.PP
The options which apply to the
\fBuserdel\fR
command are:
.PP
\fB\-f\fR, \fB\-\-force\fR
.RS 4
This option forces the removal of the user account, even if the user is still logged in\&. It also forces
\fBuserdel\fR
to remove the user\*(Aqs 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
\fBUSERGROUPS_ENAB\fR
is defined to
\fIyes\fR
in
/etc/login\&.defs
and if a group exists with the same name as the deleted user, then this group will be removed, even if it is still the primary group of another user\&.
.sp
\fINote:\fR
This option is dangerous and may leave your system in an inconsistent state\&.

.RS 4
Apply changes in the
\fIPREFIX_DIR\fR
directory and use the configuration files from the
\fIPREFIX_DIR\fR

.RE
.PP
\fB\-Z\fR, \fB\-\-selinux\-user\fR

If
\fBUSERGROUPS_ENAB\fR
is defined to
\fIyes\fR
in
/etc/login\&.defs,
\fBuserdel\fR
will delete the group with the same name as the user\&. To avoid inconsistencies in the passwd and group databases,
\fBuserdel\fR
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
\fB\-f\fR
option can force the deletion of this group\&.
