Try the following way 

#!/bin/sh
[ `whoami` = root ] || exec su -c $0 root
//your rest of the script

exec, which means "replace this program by", which effectively ends its execution and starts the new program, launched by su, with root, to run from the top

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

I'm trying to write a python 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?
