By using psutil: import psutil, os def kill_proc_tree(pid, including_parent=True): parent = psutil.Process(pid) children = parent.children(recursive=True) for child in children: child.kill() gone, still_alive = psutil.wait_procs(children, timeout=5) if including_parent: parent.kill() parent.wait(5) me = os.getpid() kill_proc_tree(me)
_posixsubprocess The file you are referencing is a Python module written in C. It’s not a “stub” file. The real implementation can be found in the stdlib at Modules/_posixsubprocess.c. You can see how writing a C/C++ extension is written by having a look at Building C and C++ Extensions. This should help you understanding the … Read more
>>> import subprocess >>> mycmd=subprocess.getoutput(‘df -h | grep home | gawk \'{ print $1 }\’ | cut -d\’/\’ -f3′) >>> mycmd ‘sda6’ >>>
Thanks for all the answers! I found a way to solve my problem by simply using select.poll to peek into standard output. import select … scan_process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) poll_obj = select.poll() poll_obj.register(scan_process.stdout, select.POLLIN) while(some_criterium and not time_limit): poll_result = poll_obj.poll(0) if poll_result: line = scan_process.stdout.readline() some_criterium = do_something(line) update(time_limit)
Since you mentioned a daemon, I can conclude that you are running on a Unix-like operating system. This matters, because how to do this depends on the kind operating system. This answer applies only to Unix, including Linux, and Mac OS X. Define a function that will set the gid and uid of the running … Read more
Just found sys.executable – the full path to the current Python executable, which can be used to run the script (instead of relying on the shbang, which obviously doesn’t work on Windows) import sys import subprocess theproc = subprocess.Popen([sys.executable, “myscript.py”]) theproc.communicate()
According to the Python os module documentation os.popen has been deprecated since Python 2.6. I think the solution for modern Python is to use check_output() from the subprocess module. From the subprocess Python documentation: subprocess.check_output(args, *, stdin=None, stderr=None, shell=False, universal_newlines=False) Run command with arguments and return its output as a byte string. If the return … Read more
If ‘somescript.py’ isn’t something you could normally execute directly from the command line (I.e., $: somescript.py works), then you can’t call it directly using call. Remember that the way Popen works is that the first argument is the program that it executes, and the rest are the arguments passed to that program. In this case, … Read more
You can pass stdout and stderr as parameters to Popen() subprocess.Popen(self, args, bufsize=0, executable=None, stdin=None, stdout=None, stderr=None, preexec_fn=None, close_fds=False, shell=False, cwd=None, env=None, universal_newlines=False, startupinfo=None, creationflags=0) For example >>> import subprocess >>> with open(“stdout.txt”,”wb”) as out, open(“stderr.txt”,”wb”) as err: … subprocess.Popen(“ls”,stdout=out,stderr=err) … <subprocess.Popen object at 0xa3519ec> >>>
I had the same problem on windows and got it work this way: Create a config file with command ipython profile create default Edit ipython_notebook_config.py file, search for line #c.NotebookApp.browser=”” and replace it with import webbrowser webbrowser.register(‘firefox’, None, webbrowser.GenericBrowser(‘C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe’)) c.NotebookApp.browser=”firefox” then it works for me. Hope it will help you. JPG
