groupadd Command

groupadd is a command-line tool in Linux and UNIX-like operating systems that is used to create a new group on the system. A group in Linux is a way to manage access to resources on the system, such as files and directories, by allowing you to assign permissions to users based on their group membership.

Here are a few examples of how to use the groupadd command:

Create a new group:

groupadd newgroup

This command creates a new group called “newgroup” on the system.

Create a new group with a specific GID(group id):

groupadd -g 1025 newgroup

This command creates a new group called “newgroup” with a GID of 1025.

Create a new group and assign a password to it:

groupadd -p password newgroup

This command creates a new group called “newgroup” and assigns the password “password” to it. This allows you to use the newgroup as a system group.

Create a new group and store it in a specific directory:

groupadd -r -g 1025 newgroup

This command creates a new system group called “newgroup” with a GID of 1025 and it will be stored in the /etc/group directory.

The groupadd command is usually executed with administrative privileges, as it allows you to create and manage groups on the system. The /etc/group file stores the group information and the /etc/gshadow stores group shadow information.

You can also use groupmod to modify or groupdel to delete an existing group.
