question on syntax - ebolisa - Oct-25-2019
Hi,
the code below should return UP but it returns DOWN and I cannot understand why.
any help is appreciated.
TIA
from __future__ import print_function
import subprocess
_cmd = 'grep RUNNING /proc/asound/card*/pcm*/sub*/status'
cmd = 'cat /proc/asound/card*/pcm*/sub*/status | grep state:'
p = subprocess.check_output(cmd,shell=True).decode("utf-8")
print(p)
#prints state: RUNNING
if (p=='state: RUNNING'):
print('UP')
else:
print('DOWN')Nevermind. I had white spaces in line.

p may have a line feed, try
if p.strip() == 'state: RUNNING':
