screen command in linux:

Command: “Ctrl-a”

Screen uses the command “Ctrl-a” that’s the control key and a lowercase “a” as a signal to send commands to screen instead of the shell.

For example, “Ctrl-a” then “?”. You should now have the screen help page.

Creating Windows

Command: “Ctrl-a” “c”.

To create a new window, you just use “Ctrl-a” “c”. This will create a new window for you with your default prompt. Your old window is still active.

Switching Between Windows

• To go to first window: "Ctrl-a" "0"
• To go to 2nd widndow: "Ctrl-a" "1"
• To go to next window: "Ctrl-a" "n", previous: "Ctrl-a" "p"

Detaching/Reattach Screen

Detaching is the most powerful part of screen. Screen allows you to detach from a window and reattach later.

You can detach from the window using: “Ctrl-a” “d”

you can re-attach by just running:

$ screen -r
$ screen -r <name_of_screen>

Create screen with name:

$ screen -S my_screen

Other Commands:

To see how many screen are available:

$ screen -ls

To Activate screen loggin:

To activate screen logging function, just press “Ctrl-A” and “H“ . (Please be careful, we use capital ‘H’ letter. Using non capital ‘h’, will only create a screenshot of screen in another file named hardcopy).

At the bottom left of the screen, there will be a notification that tells you like: Creating logfile “screenlog.0“. You will find screenlog.0 file in your home directory.

Another way to activate logging feature, you can add the parameter “-L” when the first time running screen:

$ screen -L
