'kill -9 process ID' signal handler

c,sockets,signals,kill

Kill -9 sends a SIGKILL, which you cannot catch or ignore. (See http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/signal.h.html ). You also cannot block SIGKILL using sigprocmask(). Any attempt to do so will be ignored. The fact that you cannot catch these SIGKILL means your program will never have a chance to run any code at...

Kill() error: no such process?

c,process,signals,posix,kill

pid1 has been killed by the time pid2 attempts to send a it a SIGUSR1. pid2 is the killer. When pid2 issues a kill(0, SIGUSR2), this sends SIGUSR2 to the entire process group, including pid1. This kills pid1, which is unprepared to receive a SIGUSR2....

How to close/kill an android app programmatically without leaving it in the background?

java,android,background,kill,close

If you want to "stop the app" that is not the same as "remove from recents" - even swiping from recents doesn't "stop your app" and "stopping your app" does not remove it from recents. Any activity will show in the recents list unless you tell it to not display...

Python SIGTERM not killing subprocess

python,subprocess,kill

I managed to fix this. Turns out the subprocess was respawning itself creating something weird which prevented python from keeping track of it. So I had to do this to fix it, However this is not the most elegant solution, and rather dangerouddangerous. Be careful if you use this, because...

How can I get a Python program to kill itself using a command run through the module sys?

python,shell,kill

You can use sys.exit() to exit the program normally. Exit the interpreter by raising SystemExit(status). If the status is omitted or None, it defaults to zero (i.e., success). If the status is an integer, it will be used as the system exit status. If it is another kind of object,...

Exclude login from automated kill SQL job

sql,kill

Without getting into the advisability of your process, is there any reason why couldn't you simply add a login-based filter to your INSERT statement for the @BusyProcess table? INSERT @BusyProcess ( SPID, Status, Login, HostName, DBName, Command, CPUTime, DiskIO, LastBatch, ProgramName ) SELECT spid, status, loginame, hostname, DB_NAME(dbid), cmd, cpu,...

Why subprocess can't successfully kill the old running process?

python,subprocess,kill,terminate

While I don't agree at all with your design, the specific problem is here: except Exception as e: terminated = True finally: p = subprocess.Popen(['python.exe', r'D:\test.py'], shell=True) In the case that an Exception was thrown, you're setting terminated to true, but then immediately restarting the subprocess. Then, later, you check:...

kill & wait in one step

linux,bash,kill,waitpid

It's not a one-liner, but would you be willing to consider spawning off the kill with a short sleep, then waiting in the main thread? Something like: (sleep 1; kill $PID) & wait $PID This addresses your concern of the PID being reused after the kill. Even if you reduce...

How to restart a process in bash or kill it on command?

Implicitly kill background processes connected to a foreground process

bash,shell,unix,background-process,kill

The background processes are child processes of the shell, but not child processes of wait, so there is no good way to propagate a signal to wait to any of the other processes. A quick and dirty way to kill all background processes, which you can put into a script...

Ruby force close IO.popen java process

ruby,popen,kill

What you may be seeing here is that you're killing the nice process and not the java process it launches. You could avoid this by launching the java process directly and then altering the nice level using renice on the PID you get. It's also worth checking that you're trying...

For Linux, how can I kill all processes in a session (with same SID) using system calls?

c,linux,system-calls,kill,sessionid

You can always use the /proc/ file system to query processes (see proc(5) for more). In particular you can then scan the /proc/PID/ directories (where PID is some numerical name like 1234, it is the relevant pid, so process of pid 1234 is described in /proc/1234/ pseudo-directory; hence you could...

How to kill process inside container? Docker top command

unix,command-line,process,docker,kill

When I reproduce your situation I see different PIDs between docker top <container> and docker exec -it <container> ps -aux. When you do docker exec the command is executed inside the container => should use container's pid. Otherwise you could do the kill without docker straight from the host, in...

Kill All Silent Processes in Bash Script

bash,kill,kill-process

Those messages aren't coming from the killall command. They're coming from the shell when it notices that one of its background child processes has died. You can prevent this by running the commands in a subshell: (phantomjs Lib/loadtester/runTests $TEST_COUNT $CLIENT_LIMIT $ACTION $PROFILE $TEST_SERVER $TEST_INCREMENT $DEBUG_MODE > "/tmp/"$TEST_COUNT"_log.txt" &) The background...

Process.Kill() doesn't seem to kill the process

c#,.net,process,kill

You started cmd.exe, then cmd.exe starts child process ping.exe. To kill ping.exe you can kill all process hierarchy.

How do I kill the 'play' process in my shell script?

linux,bash,shell,kill,mint

I think what might be happening is... When you do, SOUND=`play -q /home/greg/Documents/deththeme.wav &` it executes play in the background and stores the stdout of that process into SOUND, which is "". This might demonstrate: #!/usr/bin/env bash SOUND=`play -q /tmp/wav.wav &` echo SOUND = "$SOUND" $SOUND Output: # ./sound.sh SOUND...

How can I address large memory usage by MoviePy?

python,memory,kill,moviepy

If I understood correctly, you want to use the different images as the frames of your video. In this case you should use ImageSequenceClip() (it's in the library, but not yet in the web docs, see here for the doc). Basically, you just write clip = ImageSequenceClip("some/directory/", fps=10) clip.write_videofile("result.mp4") And...

emacs: Can't Kill Minibuffer

emacs,elisp,kill,minibuffer

Just do this: (define-key minibuffer-local-map "\M-s" nil) The problem is that M-s is locally bound in the minibuffer (in minibuffer-local-must-match-map and other minibuffer keymaps) to next-matching-history-element, which gives you that prompt and lets you search the history. What you need to do is unbind M-s in each of the minibuffer...

How to automatically rerun a python program after it finishes? Supervisord?

python,kill,supervisord,pyv8

I don't see why you couldn't use supervisord. The configuration is really simple and very flexible and it's not limited to python programs. For example, you can create file /etc/supervisor/conf.d/myprog.conf: [program:myprog] command=/opt/myprog/bin/myprog --opt1 --opt2 directory=/opt/myprog user=myuser Then reload supervisor's config: $ sudo supervisorctl reload and it's on. Isn't it simple...

Python: how to kill child process(es) when parent dies?

python,linux,windows,subprocess,kill

Heh, I was just researching this myself yesterday! Assuming you can't alter the child program: On Linux, prctl(PR_SET_PDEATHSIG, ...) is probably the only reliable choice. (If it's absolutely necessary that the child process be killed, then you might want to set the death signal to SIGKILL instead of SIGTERM; the...
