I've been musy with the os command on how to kill a process. That's been sorted out to an extend. Many thanks for your input.
Now I have a question in the same direction: I use os.execpv(cmd, [cmd, args]). That executes the command that have output. This was the best way of getting the pid and killing the process after a certain time. This is my code: import os, signal, time pid = os.fork() print 'pid; ',pid if pid == 0: #child process os.execvp('tcpdump', ['tcpdump', '-np']) # Need syntax to add another arg time.sleep(5) # let it run for 5 seconds kill(pid) # kill the process def kill(pid, signal=signal.SIGTERM): print "trying to kill pid...", pid os.kill(pid, signal) os.waitpid(pid, 0) print "Killed %d"%pid How do I capture that output to a file? Can I use os.popen() or something like that after I did the os.execvp() execution or is there a standard way of putting any output in a file/ Thanks, _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
