Almost There - os.kill()

Always be careful with int() incase any of the values have a leading
zero - check the documentation for int() carefully.

Woops,

 

Spoke too soon, just wrapped them in int() and it works a charm :-D

Hello Guys,

 

Finally got around to sitting down to tidy up this script this morning
but I'm having a small syntax problem with os.kill() to kill a process
on my system. Here is the code:

 

def killApplication():

 

       pid = file('/var/lock/MyApplication.lock').read().strip()

       

       logging.info('Killing Application Process: %s' % pid)

 

       os.kill(pid, 15)

 

       logging.info('Application %s Killed' % pid)

 

As you can see if rips the PID from the lock file, which works fine as I
get log data which says 'Killing Application Process: 3079' exactly as I
would expect it too. However when I run this script I get the following
error:

 

Traceback (most recent call last):

  File "/pblue/new/Alive.py", line 50, in ?

    main()

  File "/pblue/new/Alive.py", line 47, in main

    doCheck()

  File "/pblue/new/Alive.py", line 43, in doCheck

    killApplication()

  File "/pblue/new/Alive.py", line 28, in killApplication

    os.kill(pid, 15)

TypeError: an integer is required

 

Which would suggest its passing those arguments in as the wrong data
types to the kill command. What is the best way to convert these?

 

Thanks guys,

 

Rob
