Creating a group

Group is a way to organize and administer user accounts in Linux. Groups are used to collectively assign rights and permissions to multiple user accounts.

Getting ready

You will need super user or root privileges to add a group to the Ubuntu server.

How to do it...

Follow these steps to create a group:

1. Enter the following command to add a new group:

   $ sudo addgroup guest
   

2. Enter your password to complete addgroup with root privileges.

How it works…

Here, we are simply adding a new group guest to the server. As addgroup needs root privileges, we need to use sudo along with the command. After creating a new group, addgroup displays the GID of the new group.

There's more…

Similar to adduser, you can use addgroup in different modes:

• Add a normal group when used without any options
• Add a system group with the--system option
• Add an existing user to an existing group when called with two non-option arguments

Check out the manual page for the addgroup(man addgroup) to get more details.
