GROUPDEL(8) 系统管理命令 GROUPDEL(8)

groupdel - 删除一个组

groupdel [选项] GROUP

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

The options which apply to the groupdel command are:

-h, --help

现实帮助信息并退出。

-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.

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。

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。

/etc/group
组账户信息。

/etc/gshadow

安全组账户信息。
