1 background

As a system administrator, we often need SSH or telent telnet to a Linux server and often run tasks that take a long time to complete, such as system backup, FTP transfer, compilation, and so on. Usually we open a remote terminal window for each of these tasks because they take too long to execute. Must wait for them to complete, during this period cannot shut down the window or disconnects, otherwise this task will be killed, all halfway.

Introduction to 2 Screen

Screens is a full-screen window manager that re-uses physical terminals between multiple processes (usually interactive shells).Each virtual terminal provides the functionality of the DEC VT100 terminal, plus several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (for example, inserting/deleting rows and supporting multiple character sets).Each virtual terminal has a rollback history buffer and allows the user to move the copy and paste mechanism of the text area between Windows. When the screen is called, it creates a single window that contains a shell (or a specified command) and then out of your way so that you can use the program in the usual way. Then you can follow the When using other programs (including more shells) to create a new (full screen) window, kill the current window, view the list of active windows, turn on and off output logging, window, view scrolling history, switch between windows, and more. All Windows run the program completely independently. When the window is not currently visible even when the entire screen session is detached from the user terminal, the program continues to run.
