Using sudo to write to a file as root from a script

Show key headers only | View raw

Hi

I'm trying to write a script that writes some content to a file root
through sudo, but it's not working at all. I am using:

  channel = 'stable'
  config_file = '/opt/ldg/etc/channel.conf'
  command = ['echo', '-n', channel, '|', 'sudo', 'tee', config_file]
  p = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
  out, _ = p.communicate()

But it seems as if this isn't doing anything.

I just want to write the contents of the variable channel to the file
/opt/ldg/etc/channel.conf. But whatever I try just doesn't work. Can
anyone offer any pointers?

Cheers

Adam
