How to add new users on Ubuntu

User information in Linux, including Ubuntu, is stored in the /etc/passwd, /etc/group, and /etc/shadow files. Adding a new user involves manually updating these files or using specialized tools provided by the operating system.

Ubuntu offers command-line tools and graphical user interface (GUI) for user management, catering to system administrators' different preferences and needs. Available command-line tools for adding users in Ubuntu include adduser and useradd. These tools handle the creation of user accounts and necessary configurations. Command-line tools provide greater control and are ideal for automation and bulk user management. They are also the only available options for Ubuntu Server.

Ubuntu also provides a GUI method to ensure a consistent and efficient user management experience. The GUI tool is handy for those who prefer a more visual approach, while the command-line tools offer flexibility and scripting capabilities.
