The command "i3status" is used to launch the i3status program, which is a utility designed to display various system information (such as CPU usage, memory usage, battery status, date & time, etc.) on the i3 window manager's bar.
i3status is highly configurable and customizable, allowing users to choose which information they want to be displayed and in what format. It can be used to enhance the functionality and visual appearance of the i3 window manager.
Once the "i3status" command is executed, it starts running the i3status service, continuously updating the information displayed on the i3 bar as the system's status changes. It usually runs in the background so that users can continue using their system while the information is constantly being updated.
