Kill detached screen session [closed]

阅读更多关于 Kill detached screen session [closed]

问题 I learned from somewhere a detached screen can be killed by screen -X -S [session # you want to kill] kill where [session # you want to kill] can be gotten from screen -ls But this doesn't work. Anything wrong? What's the correct way? 回答1: "kill" will only kill one screen window. To "kill" the complete session, use quit . Example $ screen -X -S [session # you want to kill] quit For dead sessions use: $ screen -wipe 回答2: You can kill a detached session which is not responding within the screen

问题 This question already has answers here : How to escape a double quote inside double quotes? (8 answers) Closed last year . I need to run a command with a syntax like this: runuser -l userNameHere -c '/path/to/command arg1 arg2' Unfortunately, I have to nest additional ' characters into the command itself and I can't tell bash to interpret these correctly.

问题 How can I run a shell script and immediately background it, however keep the ability to inspect its output any time by tailing /tmp/output.txt It would be nice if I can foreground the process too later. PS It would be really cool if you can also show me how to "send" the backgrounded process in to a gnu screen that may or may not have been initialized. 回答1: To 'background' a process when you start it Simply add an ampersand ( & ) after the command. If the program writes to standard out, it

How to create a screen executing given command?

阅读更多关于 How to create a screen executing given command?

问题 i'm fairly new in *nix. Is there a way to create a screen, which will immediately execute a given command sequence (with their own arguments)? Two hours of googling yields nothing - perhaps because I can't clearly state the question. I hope for something like screen -dmS new_screen exec "cd /dir && java -version" I am using screen v4.00.03 and CentOS 5.5 (kernel ver. 2.6.18-194.26.1.el5.028stab079.2) 回答1: The problem is that using the 'exec' screen command does not start a shell. 'cd' is a

阅读更多关于 How can I tell whether I'm in a screen?

问题 When using screen in linux, how can I tell if I'm in a screen or not? I could do exit and I'll exit a screen if I was in one, but if I wasn't, then I'll end up closing my terminal. When doing screen -r , I could see if I have other screens attached, but how do I know if my current terminal is one of those attached screens? 回答1: Check $STY . If it's null, you're on a "real" terminal. If it contains anything, it's the name of the screen you're in. If you are not in screen: eric@dev ~ $ echo

Binding M-<up> / M-<down> in Emacs 23.1.1

阅读更多关于 Binding M- / M- in Emacs 23.1.1

I'm trying to put in a feature that I miss from Eclipse, where Alt +[ Up / Down ] transposes the lines up or down, but can not for the life of me figure out how to assign to these keys properly. I am using it in -nw mode (so just in a shell window), and typically run in a screen session. Using a global key binding, I can get it to work with letter combinations, like (kbd "M-m") , but every combination I have tried for the arrow keys just gives me a message that doesn't make sense, I always get: "ESC <up> is undefined" What I have tried: (global-set-key (kbd "M-<up>") 'transpose-line-up)

Send commands to a GNU screen

阅读更多关于 Send commands to a GNU screen

问题 I have a GNU screen named demo, I want to send commands to it. How do I do this? screen -S demo -X /home/aa/scripts/outputs.sh yeilds No screen session found. and doing screen -ls shows that it isn't running. 回答1: If the Screen session isn't running, you won't be able to send things to it. Start it first. Once you've got a session, you need to distinguish between Screen commands and keyboard input. screen -X expects a Screen command. The stuff command sends input, and if you want to run that

问题 I'm starting a number of screens in a bash script, then running django's runserver command in each of them. I'd like to be able to programmatically stop them all as well, which requires me to send Control+c to runserver . How can I send these keystrokes from my bash script? 回答1: Ctrl+C sends a SIGINT signal. kill -INT <pid> sends a SIGINT signal too: # Terminates the program (like Ctrl+C) kill -INT 888 # Force kill kill -9 888 Assuming 888 is your process ID. Note that kill 888 sends a
