Users and Groups in Linux : Create, List, Add, Edit, Assign, and Delete

Users and Groups in Linux

In Linux, every file has an owner and a group associated with it. Each user has a unique user ID (UID) and each group has a unique group ID (GID). These IDs are used by the operating system to determine which users and groups have permission to access which files.

In this article, we will discuss how to create, list, add, edit, assign, and delete users and groups in Linux.

Creating Users and Groups

The first step in managing users and groups is to create them. This can be done with the useradd and groupadd commands.

To create a new user, use the useradd command. This command will also create a new group with the same name as the user.

# useradd john

To create a new group, use the groupadd command.

# groupadd admin

Listing Users and Groups

Once you have created some users and groups, you will probably want to list them. This can be done with the userlist and grouplist commands.

To list all users, use the userlist command.

# userlist

To list all groups, use the grouplist command.

# grouplist

Adding Users to Groups

Once you have created some users and groups, you will probably want to add some users to groups. This can be done with the usermod command.

To add a user to a group, use the usermod command with the -a (add) option.

# usermod -a -G admin john

Editing Users and Groups

Once you have created some users and groups, you will probably want to edit them. This can be done with the usermod and groupmod commands.

To edit a user, use the usermod command.

# usermod -c “John Smith” john

To edit a group, use the groupmod command.

# groupmod -n admin administrators

Assigning Ownership of Files

In Linux, every file has an owner and a group associated with it. The owner of a file has the ability to change the file’s permissions. The group of a file has the ability to read and execute the file.

To change the owner of a file, use the chown (change owner) command.

# chown john file.txt

To change the group of a file, use the chgrp (change group) command.

# chgrp admin file.txt

Deleting Users and Groups

Once you have created some users and groups, you will probably want to delete them. This can be done with the userdel and groupdel commands.

To delete a user, use the userdel command.

# userdel john

To delete a group, use the groupdel command.

# groupdel admin

How do you remove a user from a secondary group in Linux?

Assuming you want to remove a user account from a group, the process is actually quite simple. All you need to do is use the usermod command with the -G (group) option.

For example, let’s say we want to remove the user account named “joe” from the group “sales”. We would use the following command:

usermod -G sales joe

This would remove the user account “joe” from the group “sales”.

If you want to remove a user account from all groups, you can use the usermod command with the -g option.

For example, to remove the user account “joe” from all groups, you would use the following command:

usermod -g joe

Keep in mind that when you use the usermod command with the -g option, you need to specify a primary group for the user account. In the example above, we are using the user account “joe” as the primary group.

Once you have removed the user account from the desired group (or groups), you will need to log out and log back in for the changes to take effect.

How do I remove a user from Linux?

Assuming you would like an article discussing how to remove a user from a Linux system:

“How do I remove a user from Linux?”

Most Linux distributions make it pretty easy to add a user to the system. You can use the useradd command to add a new user. You can also use the adduser command, which is a front-end to the useradd command. But what if you want to remove a user?

The userdel command will delete a user from the system. But that’s not all. The userdel command will also delete the user’s home directory and mail spool. If you don’t want to delete the user’s home directory and mail spool, you can use the –r option.

Say you want to delete the user jane. You would issue the command:

userdel jane

This would delete the user jane from the system. But it would also delete the user’s home directory, which might not be what you want.

If you want to delete the user but not the user’s home directory, you would use the –r option like this:

userdel –r jane

This would delete the user jane but leave the user’s home directory intact.


How add and remove user in Linux?

Assuming you would like an article discussing how to add and remove users in Linux:

Adding and removing users is a core administrative task in any operating system, and Linux is no different. In Linux, there are multiple ways to add and remove users, but we will focus on the two most common methods.

The first method is to use the useradd command. The useradd command is the primary tool for creating new users in Linux. To add a new user, we simply need to run the command with the username we want to create:

useradd new_user

This will create a new user with the username new_user. By default, the new user will not have a password set, so we will need to set one before the user can login. To set the password, we can use the passwd command:

passwd new_user

You will be prompted to enter and confirm the new password for the user. Once the password is set, the user can login and use the system.

The second method for adding users is to use the adduser command. The adduser command is a wrapper around the useradd command that provides a simpler interface for adding users. To add a new user with adduser, we simply need to run the command with the username we want to create:

adduser new_user

This will create a new user just like the useradd command. The main difference is that adduser will also prompt you for a password for the new user and set the password for you.

Once the user is created, you may want to add the user to one or more groups. By default, most Linux distributions will create a few groups for common purposes, such as the wheel group (for system administrators) or the plugdev group (for users who need to access USB devices). To add a user to a group, we can use the usermod command:

usermod -a -G group_name new_user

This will add the user new_user to the group group_name. You can add a user to multiple groups by specifying multiple -G options.

If you need to remove a user from a group, you can use the same command with the -G option replaced by -R:

usermod -a -R group_name new_user

This will remove the user new_user from the group group_name.

If you need to delete a user entirely, you can use the userdel command. The userdel command will delete the user and their home directory. To delete a user, we simply need to specify the username:

userdel new_user

Be careful when using the userdel command, as there is no way to recover a deleted user or their files.

These are the basics of adding and removing users in Linux. For more information on any of the commands used here, consult the man pages or the documentation for your distribution.

Which command removes the admin group from the system?

The “Which command removes the admin group from the system?” question can be a little tricky to answer, as there is no one specific command that will remove the admin group from a system. Instead, there are a few different commands that can be used to accomplish this task.

First, the “groupdel” command can be used to remove a group from the system. This command will take the group name as an argument, and will remove the group from the system.

Next, the “gpasswd” command can also be used to remove a group from the system. This command will take the group name as an argument, and will remove the group from the system.

Finally, the “userdel” command can be used to remove a user from a group. This command will take the username as an argument, and will remove the user from the group.

These are just a few of the commands that can be used to remove a group from the system. There are many other commands that can be used for this purpose as well.


How do I delete a Linux user without a directory?

Linux is a very versatile operating system, and that extends to the user management. You can easily add and remove users as needed. There are a few different ways to do this, but we’ll focus on the most common: using the userdel command.

The userdel command can be used to delete a user from the system. But, before we get to that, it’s important to understand that deleting a user is more than just removing their account. It also involves removing their home directory and any other files they may have created. So, if you’re sure you want to delete a user and all their files, then read on.

The first thing you’ll need to do is find out the name of the user you want to delete. The easiest way to do this is to use the whoami command. This will print out the current user’s name.

Next, you’ll need to use the userdel command to delete the user. The syntax for this command is:

userdel [options] username

The options we’ll be using are -r (to remove the user’s home directory) and -f (to force the deletion). So, the full command would be:

userdel -rf username

And that’s it! This will delete the user and all their files. Just be sure that you really want to do this before you run the command.
