🖥️Using screen on Linux

The screen command is a powerful tool that allows you to run multiple terminal sessions in the background, even after disconnecting. It’s especially useful when installing and managing multiple nodes on a single server. Think of it like having multiple open apps on your phone — you can easily switch between them without interrupting anything.
