.SH "SYNOPSIS"
.HP \w'\fBuserdel\fR\ 'u
\fBuserdel\fR [options] \fILOGIN\fR
.SH "DESCRIPTION"
.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 "OPTIONS"
.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\&.
.RE
.PP
\fB\-h\fR, \fB\-\-help\fR
.RS 4
Afficher un message d\*(Aqaide et quitter\&.
.RE
.PP
\fB\-r\fR, \fB\-\-remove\fR
.RS 4
Les fichiers pr\('esents dans le r\('epertoire personnel de l\*(Aqutilisateur seront supprim\('es en m\(^eme temps que le r\('epertoire lui\-m\(^eme, ainsi que le r\('epertoire d\*(Aqattente des courriels\&. Vous devrez rechercher et \('eliminer vous\-m\(^eme les fichiers situ\('es dans d\*(Aqautres syst\(`emes de fichiers\&.
.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\-P\fR, \fB\-\-prefix\fR\ \&\fIPREFIX_DIR\fR
.RS 4
Apply changes in the
\fIPREFIX_DIR\fR
directory and use the configuration files from the
\fIPREFIX_DIR\fR
directory\&. This option does not chroot and is intended for preparing a cross\-compilation target\&. Some limitations: NIS and LDAP users/groups are not verified\&. PAM authentication is using the host files\&. No SELINUX support\&.
.RE
.PP

.SH "CONFIGURATION"
.PP
The following configuration variables in
/etc/login\&.defs
change the behavior of this tool:
.PP
\fBMAIL_DIR\fR (string)
.RS 4
R\('epertoire d\*(Aqattente des courriels (\(Fo\ \&mail spool directory\ \&\(Fc)\&. Ce param\(`etre est n\('ecessaire pour manipuler les bo\(^ites \(`a lettres lorsque le compte d\*(Aqun utilisateur est modifi\('e ou supprim\('e\&. S\*(Aqil n\*(Aqest pas sp\('ecifi\('e, une valeur par d\('efaut d\('efinie \(`a la compilation est utilis\('ee\&.
.RE
.PP
\fBMAIL_FILE\fR (string)
.RS 4
D\('efinir l\*(Aqemplacement des bo\(^ites aux lettres des utilisateurs relativement \(`a leur r\('epertoire personnel\&.
.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
La valeur par d\('efaut est 0, ce qui signifie qu\*(Aqil n\*(Aqy a pas de limites pour le nombre de membres dans un groupe\&.
.sp
Cette fonctionnalit\('e (groupe d\('ecoup\('e) permet de limiter la longueur des lignes dans le fichier de groupes\&. Ceci est utile pour s\*(Aqassurer que les lignes pour les groupes NIS ne sont pas plus grandes que 1024 caract\(`eres\&.
.sp
Si vous avez besoin de configurer cette limite, vous pouvez utiliser 25\&.
.sp
Remarque\ \&: les groupes d\('ecoup\('es ne sont peut\-\(^etre pas pris en charge par tous les outils (m\(^eme dans la suite d\*(Aqoutils Shadow)\&. Vous ne devriez pas utiliser cette variable, sauf si vous en avez vraiment besoin\&.
.RE
.PP
\fBUSERDEL_CMD\fR (string)
.RS 4
Si d\('efinie, la commande est ex\('ecut\('ee lors de la suppression d\*(Aqun utilisateur\&. Elle pourra supprimer toutes les t\(^aches p\('eriodiques cron ou at, tous les travaux d\*(Aqimpression, etc\&. de l\*(Aqutilisateur (qui sera fourni comme premier param\(`etre)\&.
.sp
Le code de retour du script n\*(Aqest pas pris en compte\&.
.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

.PP
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\&.
