I have multiple screens running on an Ubuntu server that are initiated as: ``` screen -dmS screen1 cmd screen -dmS screen2 cmd etc... ``` And I need to kill one screen, but not all of them. What is the correct command to kill a single particular screen with its name? I've read through the [man pages](http://www.manpagez.com/man/1/screen/) but I can't seem to find the command I am looking for. Also I want to write this command into a bash script so I can't simply **`screen -r screen1`** then press `Ctrl`\+`X` as I normally would. - [bash](https://serverfault.com/questions/tagged/bash "show questions tagged 'bash'") - [gnu-screen](https://serverfault.com/questions/tagged/gnu-screen "show questions tagged 'gnu-screen'") - [kill](https://serverfault.com/questions/tagged/kill "show questions tagged 'kill'") [Share](https://serverfault.com/q/96406 "Short permalink to this question") Share a link to this question Copy link [CC BY-SA 3.0](https://creativecommons.org/licenses/by-sa/3.0/ "The current license for this post: CC BY-SA 3.0") [Improve this question](https://serverfault.com/posts/96406/edit) Follow Follow this question to receive notifications [edited May 23, 2017 at 16:40](https://serverfault.com/posts/96406/revisions "show all edits to this post") [](https://serverfault.com/users/205542/chicks) [chicks](https://serverfault.com/users/205542/chicks) 3,9031010 gold badges3030 silver badges3737 bronze badges asked Dec 21, 2009 at 18:45 [](https://serverfault.com/users/29651/basskozz) [BassKozz](https://serverfault.com/users/29651/basskozz) 67533 gold badges88 silver badges1515 bronze badges 6 - Sorry, thought this was about Donkey Kong for a second Chopper3 – [Chopper3](https://serverfault.com/users/1435/chopper3 "101,846 reputation") 2009-12-21 18:46:37 +00:00 [Commented Dec 21, 2009 at 18:46](https://serverfault.com/questions/96406/kill-a-screen-but-not-all-screens#comment80276_96406) - I love this t-shirt [ohgizmo.com/wp-content/uploads/2008/11/…](http://www.ohgizmo.com/wp-content/uploads/2008/11/donkeykong_killscreen.jpg) Chopper3 – [Chopper3](https://serverfault.com/users/1435/chopper3 "101,846 reputation") 2009-12-21 18:57:50 +00:00 [Commented Dec 21, 2009 at 18:57](https://serverfault.com/questions/96406/kill-a-screen-but-not-all-screens#comment80282_96406) - That is a nice tee, most people won't get it thou, unless they've seen "The King of Kong": [imdb.com/title/tt0923752](http://www.imdb.com/title/tt0923752/) BassKozz – [BassKozz](https://serverfault.com/users/29651/basskozz "675 reputation") 2009-12-21 19:07:18 +00:00 [Commented Dec 21, 2009 at 19:07](https://serverfault.com/questions/96406/kill-a-screen-but-not-all-screens#comment80287_96406) - The correct word for an object of a phrase is "thee".

If you do a `screen -list`, you'll notice that each screen name begins with a number, which is the PID of the screen: ``` $ screen -list There are screens on: 12281.pts-1.jonah (12/21/2009 07:53:19 PM) (Attached) 10455.pts-1.jonah (12/19/2009 10:55:25 AM) (Detached) 2 Sockets in /var/run/screen/S-raphink. ``` From there, just send a KILL signal to this specific PID: ``` $ kill 12281 ``` and it will kill the specific screen.

If you have several screens with the same name, you can kill them at once: ``` screen -ls | egrep "^\s*[0-9]+.ScreenName" | awk -F "." '{print $1}' | xargs kill ``` - Command `screen -ls` prints screens with their process number. For example, **4773\.test** is a screen with process number **4773** and the name **test**. Sample output: ``` 6322.ss (05/23/2018 10:39:08 AM) (Detached) 6305.sc (05/23/2018 10:38:40 AM) (Detached) 6265.ScreenName (05/23/2018 10:37:59 AM) (Detached) 6249.ScreenName (05/23/2018 10:37:50 AM) (Detached) 6236.scc (05/23/2018 10:37:42 AM) (Detached) ``` - Command `egrep` filters above sample text sent via piped line **\|**. - Command `awk -F "." '{print $1}'` extracts first column of each line. Delimiter between columns is defined as **dot (.)** by option **\-F** - Finally command `xargs kill` will kill all process whose numbers sent via pipe \|. `xargs` is used when we want to execute a command on each of inputs.

Ive been dealing with this as follows: ``` process=$(screen -ls | grep screen1) kill $(echo $process | cut -f1 -d'.') exit ``` The explanation is that you take the output of `screen -ls` and find the particular screen you are interested in by using grep then assign that string to the variable `process`. Since the output from `screen -ls` is always the PID followed by a period you can then use cut to get rid of the period and everything after it. in the above example we put that in parentheses and feed it to the kill command though you could do it linearly which might include writing to a temp file and reading out of that. You need to make sure that your screen name is unique and that grep is ONLY returning the name of the screen you want to kill.
