СИНОПСИС

userdel [options] LOGIN

ОПИСАНИЕ

The userdel command modifies the system account files, deleting all entries that refer to the user name LOGIN. The named user must exist.

ПАРАМЕТРЫ

The options which apply to the userdel command are:

-f, --force
    This option forces the removal of the user account, even if the user is still logged in. It also forces userdel 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 USERGROUPS_ENAB is defined to yes 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.

    Note: This option is dangerous and may leave your system in an inconsistent state.

-h, --help
    Показать краткую справку и закончить работу.

-r, --remove
    Файлы в домашнем каталоге пользователя будут удалены вместе с самим домашним каталогом и почтовым ящиком. Пользовательские файлы, расположенные в других файловых системах, нужно искать и удалять вручную.

    The mail spool is defined by the MAIL_DIR variable in the login.defs file.

-R, --root CHROOT_DIR
    Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory. Only absolute paths are supported.

-P, --prefix PREFIX_DIR
    Apply changes in the PREFIX_DIR directory and use the configuration files from the PREFIX_DIR 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.

-Z, --selinux-user
    Удаляет все пользовательские сопоставления SELinux для учётной записи пользователя.

НАСТРОЙКА

The following configuration variables in /etc/login.defs change the behavior of this tool:

ФАЙЛЫ

/etc/group
    содержит информацию о группах

/etc/login.defs
    содержит конфигурацию подсистемы теневых паролей

/etc/passwd
    содержит информацию о пользователях

/etc/shadow
    содержит защищаемую информацию о пользователях

/etc/shadow-maint/userdel-pre.d/*, /etc/shadow-maint/userdel-post.d/*
    Run-part files to execute during user deletion. The environment variable ACTION will be populated with userdel and SUBJECT with the username. userdel-pre.d will be executed prior to any user deletion. userdel-post.d will execute after user deletion. If a script exits non-zero then execution will terminate.

/etc/subgid
    Per user subordinate group IDs.

/etc/subuid
    Per user subordinate user IDs.

ВОЗВРАЩАЕМЫЕ ЗНАЧЕНИЯ

0
    success

1

2

ПРЕДОСТЕРЕЖЕНИЯ

userdel 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 -f option can force the deletion of this account.

Вы должны вручную проверить все файловые системы, чтобы убедиться, что не осталось файлов, принадлежащих этому пользователю.

Нельзя удалить NIS атрибуты клиента NIS. Это необходимо сделать на NIS сервере.

If USERGROUPS_ENAB is defined to yes in /etc/login.defs, userdel will delete the group with the same name as the user. To avoid inconsistencies in the passwd and group databases, userdel 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 -f option can force the deletion of this group.
