名称
groupdel - 删除一个组

大纲

groupdel [选项] GROUP

描述

The groupdel command modifies the system account files, deleting all entries that refer to GROUP. The named group must exist.

选项

The options which apply to the groupdel command are:

-f, --force
    This option forces the removal of the group, even if there's some user having the group as the primary one.

-h, --help
    显示帮助信息并退出。

-R, --root CHROOT_DIR
    Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.

-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.

CAVEATS

您不能移除现有用户的主组。在移除此组之前，必须先移除此用户。

您需要手动检查所有文件系统，以确保没有遗留的属于此组的文件。

配置文件

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

MAX_MEMBERS_PER_GROUP (number)
    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).

    默认值是 0，意味着组中的成员数没有限制。

    此功能(分割组)允许限制组文件中的行长度。这对于确保 NIS 组的行比长于 1024 字符。

    如果要强制这个限制，可以使用 25。

    注意：分割组可能不受所有工具的支持(甚至在 Shadow 工具集中)。您不应该使用这个变量，除非真的需要。

文件

/etc/group
    组账户信息。

/etc/gshadow
    安全组账户信息。

退出值

The groupdel command exits with the following values:

0
    success

2
    invalid command syntax

6
    specified group doesn't exist

8
    can't remove user's primary group

10
    can't update group file
