Kill Attached Screen in Linux

I created a screen "myscreen" in linux and it stopped responding abruptly. I closed the terminal and tried to reopen it. "screen -ls" shows that the screen is Attached. I tried the following commands but nothing responds.

screen -r myscreen
screen -D myscreen
screen -D -RR myscreen
screen -X -S myscreen quit

Any help to reattach to the screen or to kill the screen is very much appreciated.

You can simply follow this procedure

If the screen is in detached state

screen -r "screenName"

exit

this will kill/ terminate the screen which you want to kill

If the screen is in attached state

screen -d -r "screenName"

exit

To kill a detached screen use this from the terminal:

screen -X -S "SCEEN_NAME" quit

If you are attached, then use (from the terminal and inside the screen):

exit

From Screen User's Manual ;

screen -d -r "screenName"

Reattach a session and if necessary detach it first

None of the screen commands were killing or reattaching the screen for me. Any screen command would just hang. I found another approach.

Each running screen has a file associated with it in:

/var/run/screen/S-{user_name}

The files in that folder will match the names of the screens when running the screen -list. If you delete the file, it kills the associated running screen (detached or attached).

You can find the process id of the attached running screen. I found it same as the session id which you can get by command:
screen -ls
And you can use following command to kill that process:
kill [sessionId] or
sudo kill [sessionId]

Suppose your screen id has a pattern. Then you can use the following code to kill all the attached screen at once. 

result=$(screen -ls | grep 'pattern_of_screen_id' -o)
for i in $result; 
do      
    `screen -X -S $i quit`;
done

This worked for me very well. Get the screen id via:

screen -r

or

screen -ls

then kill the screen: kill -9 <screenID> it now becomes a dead screen, then wipe it out with: screen -wipe

Screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows the user to move text regions between windows.

Create screen from Terminal:

screen -S <screen_name>

To see list of screens:

<screen -ls> or <screen -list>

To go to particular screen:

<screen -x screen_name>

<screen -r screen_name>

Inside screen

To Terminate screen:

give ctrl+d screen will get terminated

To Detach screen:

 give <ctrl+ad>or <screen -d >screen will get detached

To reattach screen:

screen -x <screen_name> or screen -r <screen_name>

To kill a screen from Terminal:

<screen -X -S screen_name quit>

or 

<screen -X -S screen_name kill>

You can use screen_name or process_id to execute commands.

You could create a function to kill all existing sessions. take a look at Kill all detached screen sessions

to list all active sessions use screen -r

when listed, select with your mouse the session you are interested in and paste it. like this

screen -r

screen -X -S SCREENID kill

alternatively, you can use the following command

screen -S SCREENNAME -p 0 -X quit

You can view the list of the screen sessions by executing screen -ls

i usually don't name my screen instances, so this might not be useful, but did you try screen -r without the 'myscreen' part? usually for me, screen -r will show the PIDs of each screen then i can reattach with screen -d -r <PID>
