| Not Working In Subprocess.call

Whenever I use a command in a subprocess with '|' in it doesn't work it has an output of Command '|' is unknown, try 'in link help'. Or when I put this: #!/usr/bin/python fro

Solution 1:

You can use subprocess.check_output method and Popen class though I wasn't able to chain both pipe operations. Partial solution:

from subprocess import check_output, Popen, PIPE
from shlex import split

process = Popen(split('ip -o link show'), stdout=PIPE)
output = check_output(('awk', '{print $2}'), stdin=process.stdout)
return_code = process.wait()
print(output, return_code)

So basically, awk is taking the process standard output, and result is saved in the output variable.
