![]() Truth be told, user management on Linux is quite simple - you just need to know which commands to work with. If you were concerned that managing users on Linux would be a challenge, you should now be able to set those concerns aside. That’s much more efficient than using grep and will only display the member names for the group ( Figure B). Once installed, the command for listing out who is in our editorial group would be: If you’re using a Ubuntu distribution, the command for installation would be: This command isn’t installed on most distributions, but can be installed from the standard repositories. The above command will list pertinent information about the group ( Figure A).Īnother method for finding out who is in a group is with the command members. How do you know which users are already a member of a group? You can do this the old-fashioned way like so: The -a option tells usermod we are appending and the -G option tells usermod we are appending to the group name that follows the option. For this we will take advantage of the usermod command. Now we want to add our new user, olivia, to the group editorial. ![]() The first command creates the user without a home directory and the second command locks the user out of logging in. Where USERNAME is the name of the user to add. If you need to create a user that has no home directory and is locked out from logging in, you can do this with the the following commands: Once the user logs in, they can change their password by using the passwd command, entering their current password, and then entering/verifying their new password. Where PASSWORD is the password you want to use for the user olivia. If you want to do this all in a single step, that command would look like this: At this point, the user account will be unlocked and they can login. You will be prompted to enter and verify the new password. If you’ve already created the user, you could issue the command: So if you looked in the /home directory, you would now see olivia.īut what about that lockout issue? There are two ways you can do this. The above command would create the user and also create the user’s home directory to match the username. ![]() Instead of issuing the command without arguments, let’s go with this: The user would be added, without a home directory and be locked out of logging in. Say, you want to create the user olivia such that she has a home directory and can log in. This command is pretty flexible and allows you to create users that can login or even users that cannot login (in the case of creating a user for a software installation). Creating usersįor this, we will be making use of the useradd command. Let’s dive in, so you can up your Linux admin game. Because of the necessity of this task I want to walk you through the process of: As for groups: Beyond having to create groups for successful installation of certain software, this is a great way to control user permissions for directories.Ĭhances are you will also have to do this from the command line. Second, you might find yourself having to create a user in order to install a piece of software. First off, new users cannot be added to a system. Without knowing how to create users, you will find yourself limited in a few crucial ways. If you administer a Linux server, you very likely will have to create users and groups.
