We are going to learn the “Linux add user to group” concept. User and group management is an essential aspect of Linux administration. It allows you to have control over user permissions, and resource allocation, and to define what each user can access on the system. Once you understand how to work with users and groups efficiently, it enhances security and enables smooth system management. In this article, we shall discuss adding users to groups, creating users, listing groups, and managing Linux Foundation subgroups. Moreover, we’ll tell you how CyberPanel simplifies administration. By the end of this article, you’ll have a complete understanding of Linux user and group management.
Understanding Linux Groups
In Linux, groups are used to organize and manage users. They grant them different permission and access rights based on their group membership. By default, every group belongs to the primary group. But, they can also be added to secondary groups to grant additional permissions.
For example, adding a user to the “docker” group allows them to run Docker commands without needing sudo permissions.
Listing Groups In Linux
You can use the following command to list groups in Linux a user belongs:
To “list groups Linux” for a particular user, you can use th
Adding A User To A Group In Linux
You can get “Linux add user to group” by using the usermod command.

Example: Add a User to a Group
You can use the following command to add an existing user to a specific group without removing them from their current groups:
-aG flag, adds users to the group without removing existing group memberships on the users.
Why is this important? If you omit -aG, you will instead remove the user from any other groups they may exist in which can lead to issues when it comes to permissions.
To add a user called “john” to the group “sudo”:
Creating A New User And Assigning To A Group
You can use the useradd command to create a user and assign them to a group simultaneously. For example, to create a new user and add user to sudo group in Linux:
This example assigns the user to a primary group. For assigning the user to additional groups during creation, you can use the following command:
This above command will add user and group in Linux. It allows you to be a part of multiple groups like sudo and developers.
You can create a new user and add them directly to the sudo group:
Linux Show Groups
To check which groups a specific user belongs to, use the following command:
For example, to view the groups for the user john:
Viewing Users In A Group
Oftentimes, one wants to know which users are members of a specific group. One can use the getent command to view group membership. With that, you can view users assigned to groups in Linux:
To view users in the sudo group:
The above command lists all users with administrative privileges on the system.
Removing A User From A Group
To remove a user from a group, you can use the gpasswd command. This may come in handy if, for instance, one needs to remove access to some system features or restrict administrative access.
To “Linux put user in group” or remove them from it, you can use:
For example, to remove “John” from the sudo group:
Linux Foundation Sub-Groups
Linux allows you to create multiple sub-groups to manage different permission levels. For instance, you can create groups under the Linux foundation subgroups like developers or admin.
To “Linux add user to group” in Linux for these sub-groups, you can execute:
Linux Useradd to Group
You can directly assign new Linux users to groups during the user creation process. This is done using the Linux useradd to group command. It is pretty useful when one creates new users for particular roles.
Command:
For example, if you want to create a new user named “jane” and assign her to the developers group, the command would look like this:
In the above case, “jane” is created with a home directory. And she is also added to a specific group.
Adding Users to Multiple Groups in Linux
You can use the usermod command with the -G option to achieve this:
For example, if you want to “Linux put user in group” “developers” and “testers”, you can run:
Example of Complete Workflow
Here is a complete workflow of creating a user, adding them to a group, and listing group memberships:
1. Create a new user named alice:
2. Put User in Group:
3. Check groups:
4. List all groups on the system:
