What is the primary function of the adduser command?

The primary function of the adduser command is to add a user to the system. This command is used in various Linux distributions to streamline the process of creating a new user account, which includes setting up the user's home directory, initial configuration files, and permissions. When executed, adduser typically prompts for essential information such as the username and password, making the task of creating a user account straightforward for administrators.

The command not only facilitates the creation of the user but also ensures that necessary system configurations are applied to the new account. This differentiates it from commands that remove users, modify their information, or change passwords, which serve distinct purposes within user management on the system.
