[python] is process running, or not?

[lazka]

how do i get the information if e.g. apache is running?

atm i do this:


def check_apache( *args ):
process = os.popen("ps x | grep apache").read().splitlines()
if len(process) > 2:
return 1
else:
return 0

2. question: how do I get the path of the python script itself?
i always have to start it in the folder to get pictures

answer to question 2: what you want is the current working directory:

import os

print os.getcwd()

answer to question 1: there are lots of ways, do what works for you

sry but thats not what i wanted
it always returns my home-directory path

current directory checking only works on where the user currently is, not the python script. You probably need to set an environmental variable to tell the script where it is.

I'm sorry but I can't understand then, you arent asking a python question but a shell question ?

What about

os.path.abspath(os.path.dirname(sys.argv[0]))

1.just one way :


process = os.popen("ps x -o pid,args | grep apache").read() #sometimes have to use grep -v grep
if process:
print "apache running"
