The biggest benefit of the screen command group is that when your shell exits or shuts down, the service you run does not matter, that is, we can open a set of services in screen without being affected by the disconnection of the terminal.

    • Package Installation Management Commands

Assuming that the package you want to install is called an app, note that commands here usually require sudo or root privileges.
