linux列出组

Linux groups are a collection of users. They are meant to easily provide privileges to a group of users. In this tutorial, we will look at various ways to list all groups in Linux.

Linux组是用户的集合。 它们旨在轻松地向一组用户提供特权。 在本教程中，我们将研究列出Linux中所有组的各种方法。

The /etc/group file contains all the local groups. So, we can open this file and look at all the groups.

/ etc / group文件包含所有本地组。 因此，我们可以打开该文件并查看所有组。

If you are looking for a specific group, then use the grep command to filter it out.

如果要查找特定的组，请使用grep命令将其过滤掉。

Linux getent command fetch entries from databases supported by the Name Service Switch libraries. We can use it to get all the groups information from the group database.

Linux getent命令从名称服务交换机库支持的数据库中获取条目。 我们可以使用它从组数据库中获取所有组信息。

Let’s look at some more examples of listing all the groups in Linux.

让我们看看列出Linux中所有组的更多示例。

We can use cut command to print only the group names. This is useful when we are looking for a specific group name presence in a shell script.

我们可以使用cut命令仅打印组名。 当我们在shell脚本中寻找特定的组名存在时，这很有用。

We can use cut command with the getent command too.

我们也可以将cut命令与getent命令一起使用。

The cut command is splitting every line using the colon (:) delimiter. Then the first field, which is the group name, is selected using the -f1 option.

cut命令使用冒号（:)分隔符分割每一行。 然后，使用-f1选项选择第一个字段，即组名。

The above commands output can be passed to the sort command to print the output in natural sorting order.

上面的命令输出可以传递给sort命令，以自然排序顺序输出输出。

If you are interested in the count of the linux groups, use the following commands.

如果您对linux组的数量感兴趣，请使用以下命令。

We can use the groups command to get all the groups of a user.

我们可以使用groups命令来获取用户的所有组。

If you run the groups command without any user input, it will print the groups of the current user.

如果您在没有任何用户输入的情况下运行groups命令，它将打印当前用户的组。

We can use id command to print the user information. This command lists all the groups along with their group id.

我们可以使用id命令来打印用户信息。 此命令列出所有组及其组ID。

We can use the getent command or the /etc/groups file to get all the users that belongs to a group.

我们可以使用getent命令或/ etc / groups文件来获取属于一个组的所有用户。

The getent command and /etc/group file can be used to get all the Linux groups details. We can use them alongside cut and sort command to present the output in a better way.

getent命令和/ etc / group文件可用于获取所有Linux组详细信息。 我们可以将它们与cut和sort命令一起使用，以更好地呈现输出。
