How to Add User on Ubuntu 22.04

In Linux, the administrator can create or add a user to the system to divide the task among other subordinate users. Administrators usually add regular users to the system to prevent them from accessing and messing up the base account. Adding multiple users on Ubuntu has many benefits, such as each user can customize the system according to their preferences and needs.

Administrators can create both regular and system users. A regular user only has administrator privileges or has access to the sudo command once you provide it. While, on the other hand, the system user is the one who has all administrator privileges and can modify critical system files and configurations.

The newusers command creates or updates the new users in bulk including regular and system users. The newusers command is mostly used in big IT companies where system administrators add a batch of users to the operating system. To add users in the batch using the newusers command, you have to create a text file first.

Syntax

Here is how to add the new user details in the text file:

Where,

• User_name: type the username you want to create
• Password: enter the username’s password
• User_ID: refers to the user ID to be created in the system
• Group_ID: refer to the group ID in the system
• User_Info: user information such as full name
• Home_Directory: refers to the user’s home directory
• Default_Shell: refers to the default shell

Check the stepwise guide below to add multiple regular users on the Ubuntu system through the newusers command.

Save the data and exit the file.

Step 2: Add Users to the Ubuntu System

Provide that “.txt” file to the newusers command (as an argument), as shown below:

Step 3: Verify the Batch User’s Creation

Check the user addition on Ubuntu by fetching the users from user ID 3 to 1000 by executing the below command:

Note: Adding multiple system users to the Ubuntu system is no different than adding the regular users except for adding the –system flag. The system user details are the same as the regular user except for adding a false value in the default shell environment and keeping the user ID range from 100-999.
