sending the signal 0 to a given PID just checks if any process with the given PID is running and you have the permission to send a signal to it. For more information see the following manpages: kill(1) $ man 1 kill … If sig is 0, then no signal is sent, but error checking … Read more
You can retrieve the process id (PID) given it name using pgrep command like this: import subprocess import signal import os from datetime import datetime as dt process_name = sys.argv[1] log_file_name = sys.argv[2] proc = subprocess.Popen([“pgrep”, process_name], stdout=subprocess.PIPE) # Kill process. for pid in proc.stdout: os.kill(int(pid), signal.SIGTERM) # Check if the process that we killed … Read more
I was able to reproduce the behavior you report. My hypothesis is that since the script is running from a non-interactive shell (as a child of a script) that SIGINT, which is a keyboard signal, is ignored. From info bash: Background processes are those whose process group ID differs from the terminal’s; such processes are … Read more
The subprocess module will be your friend. Start the process to get a Popen object, then pass it to a function like this. Note that this only raises exception on timeout. If desired you can catch the exception and call the kill() method on the Popen process. (kill is new in Python 2.6, btw) import … Read more
The only solution I was able to find was to check a global static variable in every instance of onCreate() and finish if that variable had been reset to null, indicating the task had been restarted. I close all activities down to my root activity and start over. Soon I hope to have my app … Read more
Simple Override onBackPressed Method: @Override public void onBackPressed() { super.onBackPressed(); this.finish(); }
You could do something like this: import subprocess as sub import threading class RunCmd(threading.Thread): def __init__(self, cmd, timeout): threading.Thread.__init__(self) self.cmd = cmd self.timeout = timeout def run(self): self.p = sub.Popen(self.cmd) self.p.wait() def Run(self): self.start() self.join(self.timeout) if self.is_alive(): self.p.terminate() #use self.p.kill() if process needs a kill -9 self.join() RunCmd([“./someProg”, “arg1”], 60).Run() The idea is that you … Read more
You can kill by job number. When you put a task in the background you’ll see something like: $ ./script & [1] 35341 That [1] is the job number and can be referenced like: $ kill %1 $ kill %% # Most recent background job To see a list of job numbers use the jobs … Read more
From man 1 pkill -f The pattern is normally only matched against the process name. When -f is set, the full command line is used. Which means, for example, if we see these lines in ps aux: apache 24268 0.0 2.6 388152 27116 ? S Jun13 0:10 /usr/sbin/httpd apache 24272 0.0 2.6 387944 27104 ? … Read more
There is a leaner way to do this using Java JNA. This works definitely for Windows and Linux, i assume that you can do the same for other platforms too. The biggest problem of Java process handling is the lack of a method to get the process id of the process started with untime.getRuntime().exec(). Assuming … Read more
