Screen command usage instructions in Linux

What is Screen command?
Screen is called a Full-screen window manager, which makes it easy to get multiple virtual terminals on a physical terminal.
Screen Feature Description:
In simple terms, screen is a window manager that can multiplex a physical terminal across multiple processes, which means you can use a single terminal window to run multiple terminal applications. Screen has the concept of a session, where users can create multiple screen windows in a screen session, as in each screens window, as in the case of a real telnet/ssh connection window.
Function Description:
When using Telnet or SSH to telnet to Linux, if the connection is disconnected abnormally, the system will open a new session and cannot restore the original Session.screen command to resolve the problem. The screen tool is a terminal multiplex, which in essence means that you can use a single terminal window to run multiple terminal applications.
Syntax
screen [-amrvx-ls-wipe][-d < job name >][-h < line >][-r < job name >][-s][-s < job name]
Supplementary Note:
Screen is a multiple Windows management program. The so-called window here refers to a Full-screen text-mode screen. The screen program is typically used only if you are using Telnet to log in to a host or use an old-fashioned terminal.
Parameters
-A adjusts all windows to the size of the current terminal.
-D < Job name > take the specified screen job offline.
-H < number of rows > The number of buffer lines for the specified window.
-M forces a new screen job to be created even if the screen job is currently in the job.
-R < Job name > Resume Offline screen job.
-R attempts to recover an offline job first. If you cannot find an offline job, create a new screen job.
-s Specifies the shell to be executed when a new window is created.
-S < job name > Specifies the name of the screen job.
-V Displays version information.
-X Offline screen job before recovery.
-ls or--list displays all current screen jobs.
-wipe checks all current screen jobs and deletes screen jobs that are no longer available.
