screen:start

The command "screen -S ${session_name}" is used to create and manage terminal screen sessions in Unix-like operating systems.

Here's a breakdown of each component:

• "screen": Refers to the command-line utility called "screen" that enables multiplexing (managing multiple virtual terminal sessions within a single physical terminal window).

• "-S": Specifies the following parameter as the session name for the screen session. The session name can be any desired alphanumeric string to identify the session.

• "${session_name}": This is a placeholder for the actual session name you want to give to the screen session. You need to replace it with a meaningful and unique name when using the command. For example, "my_session" or "web_server".

By running this command, you create a new screen session with the provided session name. This session allows you to run multiple terminal processes or applications concurrently. The screen session remains active even if you disconnect from the remote server or log out of the terminal. You can later reattach to the screen session and resume the processes from where you left off.
