I am trying to extract the available userspace+swap memory and then want to
feed this value as an argument to a tool that is executed in the shell.
so, this is what I have so far:
reecalc = [s.split() for s in os.Popen("free -ht").read().splitlines()]
freecalc_total = freecalc
freecalc_total = freecalc_total
freecalc_total = freecalc_total.translate(None, 'M’)
Now I want to feed the value for ‘freecalc_total’ as an argument to a command
executed by the shell.
devnull = open(os.devnull, “w”)
runCommand = subprocess.call([“stressapptest”, “<I want to pass the value of
freecalc_total here>”, “20”],stdout=devnull,stderr=subprocess.STDOUT)
How do I go about doing this?
Many thanks in advance
