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,
