\fBuserdel\fR [opcje] \fILOGIN\fR
.SH "OPIS"
.PP
\fBuserdel\fR
is a low level utility for removing users\&. On Debian, administrators should usually use
\fBdeluser\fR(8)
instead\&.
.PP
The
\fBuserdel\fR
command modifies the system account files, deleting all entries that refer to the user name
\fILOGIN\fR\&. The named user must exist\&.
.SH "OPCJE"
.PP

.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\&.

This option is dangerous and may leave your system in an inconsistent state\&.

.RE
.PP
\fB\-r\fR, \fB\-\-remove\fR
.RS 4
Files in the user\*(Aqs home directory will be removed along with the home directory itself and the user\*(Aqs mail spool\&. Files located in other file systems will have to be searched for and deleted manually\&.
.sp
The mail spool is defined by the
\fBMAIL_DIR\fR
variable in the
login\&.defs
file\&.
.RE
.PP
\fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR
.RS 4
Apply changes in the
\fICHROOT_DIR\fR
directory and use the configuration files from the
\fICHROOT_DIR\fR
directory\&.
.RE
.PP
\fB\-Z\fR, \fB\-\-selinux\-user\fR
.RS 4
Remove any SELinux user mapping for the user\*(Aqs login\&.
.RE
.SH "CONFIGURATION"
.PP
The following configuration variables in
/etc/login\&.defs
change the behavior of this tool:
.PP
\fBMAIL_DIR\fR (string)
.RS 4
The mail spool directory\&. This is needed to manipulate the mailbox when its corresponding user account is modified or deleted\&. If not specified, a compile\-time default is used\&.
.RE
.PP
\fBMAIL_FILE\fR (string)
.RS 4
Defines the location of the users mail spool files relatively to their home directory\&.
.RE
.PP
The
\fBMAIL_DIR\fR
and
\fBMAIL_FILE\fR
variables are used by
\fBuseradd\fR,
\fBusermod\fR, and
\fBuserdel\fR
to create, move, or delete the user\*(Aqs mail spool\&.
.PP
\fBMAX_MEMBERS_PER_GROUP\fR (number)
.RS 4
Maximum members per group entry\&. When the maximum is reached, a new group entry (line) is started in
/etc/group
(with the same name, same password, and same GID)\&.
.sp
The default value is 0, meaning that there are no limits in the number of members in a group\&.
.sp
This feature (split group) permits to limit the length of lines in the group file\&. This is useful to make sure that lines for NIS groups are not larger than 1024 characters\&.
.sp
If you need to enforce such limit, you can use 25\&.
.sp
Note: split groups may not be supported by all tools (even in the Shadow toolsuite)\&. You should not use this variable unless you really need it\&.
.RE
.PP
\fBUSERDEL_CMD\fR (string)
.RS 4
If defined, this command is run when removing a user\&. It should remove any at/cron/print jobs etc\&. owned by the user to be removed (passed as the first argument)\&.
.sp
The return code of the script is not taken into account\&.
.sp
Here is an example script, which removes the user\*(Aqs cron, at and print jobs:
.sp
.if n \{\
.RS 4
.\}
.nf
#! /bin/sh

# Check for the required argument\&.
if [ $# != 1 ]; then
	echo "Usage: $0 username"
	exit 1
fi

# Remove cron jobs\&.
crontab \-r \-u $1

# Remove at jobs\&.
# Note that it will remove any jobs owned by the same UID,
# even if it was shared by a different username\&.
AT_SPOOL_DIR=/var/spool/cron/atjobs
find $AT_SPOOL_DIR \-name "[^\&.]*" \-type f \-user $1 \-delete \e;

# Remove print jobs\&.
lprm $1

# All done\&.
exit 0
      
.fi
.if n \{\
.RE
.\}
.sp
.RE
.PP
\fBUSERGROUPS_ENAB\fR (boolean)
.RS 4
If set to
\fIyes\fR,
\fBuserdel\fR
will remove the user\*(Aqs group if it contains no more members, and
\fBuseradd\fR
will create by default a group with the name of the user\&.

\fBuserdel\fR
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\*(Aqs password or account and remove the account later\&. The
\fB\-f\fR
option can force the deletion of this account\&.
.PP
You should manually check all file systems to ensure that no files remain owned by this user\&.
.PP
You may not remove any NIS attributes on a NIS client\&. This must be performed on the NIS server\&.

If
\fBUSERGROUPS_ENAB\fR
is defined to
\fIyes\fR
in

\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\&.
