Linux is a multi-user operating system. Each account on the system has a unique username. This is the name the user uses to log in to the system. It is also the name of the user's home directory. Every Linux distribution uses the "usermod" command to modify user accounts. This includes changing the user name for a particular account. The "usermod" command can only be used by the root user. The root user can modify every account that accesses the operating system.
