subprocess.call

Question

I am new to the subprocess.call function and I have tried different combinations of the same call but it is not working.

I am trying to execute the following command

Answer 1

example:

subprocess.call(['ps','aux'])
lines=subprocess.check_output(['ls','-al'])
line_list = lines.split('\n')

or

handle = subprocess.Popen('ls',stdin=subprocess.PIPE,stdout=subprocess.PIPE,stderr=subprocess.PIPE,close_fds=True)
handle.stdout.read()
