How to Add User to Group in Linux
Linux is a user friendly operating system that allows a user to either belong to an individual or group of users. Each user group is broken into several groups, for example, root, users, other users, Administrators, and so on. To be a member of any user group, you must have a username and a password. This is normally done via the command line prompt, which can either be by the side bar or as part of the setup file, .Env. There are also other methods of getting a user group, such as with a distribution like Red Hat or Fedora. This article will describe how to add a user to a group.
To add a user to a group, first ensure that the group is enabled in your configuration. To do this, run the command ‘groups’ to check whether the user group is already activated. If it is not, go to the file system and create the user group, or add the user if it is already present. This can be done by first logging onto your Linux system, and then cd to the /etc/passwords directory to activate the usergroup. If you are adding a user, you will be asked to enter their passphrase, which will grant access to the group.
Next, create a file called ‘users’, where you will store all the user information. You can create this directory yourself, or depending on the operating system you are using, there should be a program installed like nano or ps. nano is highly recommended because it allows you to make very detailed notes about the users you have added. For example, you can enter the user name and specify the password for the group. If you have more than one user, you can add the users in groups. Otherwise, you need to specify the group name and the username to be able to log into the groups.
You can add the new users to groups using the command ‘add group user’. Type the new user name and their passphrase into the ‘file’ box. Type the same information for the other members of the groups as well. This will populate the file so that when you log in as the new user, his profile will be shown up.
The next step is to log into your Linux system as the root user, and then type the group name of the group you created (in the example above it would be ‘testing’). This will create a hierarchy in your file that the other users can navigate. Now, let’s checkout the file where we specified the usergroups: users. It will display the list of user groups that the user is a member of. If you click on the user group named ‘testing’ it will take you to a page containing additional information about the user, his role, email address, etc.
In the above case, we used the dot at the end of the username to indicate that it is a username that should be treated specially when adding to another group. If you do not have a dot at the end, the character you are typing will be treated as a colon. The supplied description field is the way in which you specify the description of the user that you have just created. For example, if you have just created the user ‘jake’ you can enter this in the Description box and then click ‘OK’.
Finally, the last step is to save the group or user groups file that you have created. You do this by clicking the ‘lish’ button on the top menu of your system. This will permanently remove any previously set usergroups or groups from your Linux system. However, you need to be sure that you know how to edit these files before you do this so that you do not cause further damage.
There are a number of other ways in which you can add user information to a Linux machine. One is to create user directories and then add the users in that directory. Another method is to provide different types of security software to a user group. Finally, there are utility programs like the crontab which allow you to set up timed jobs. These are just some of the ways in which you can make changes to user groups in your Linux machine.
