Re: [BangPypers] Redirection of standard output to a variable

In that case, why not use what gnuyoga suggested - i.e. - commands.getstatusoutput(scp ...). If the first entry in the returned tuple is 0, the command executed successfully, if not, then it didn't :). I think you can trust python to get the correct exit code without actually parsing the output

Re: [BangPypers] Redirection of standard output to a variable

Hi Rishabh, My script needs to fetch some critical config files from 200+ servers, process them and put them back in place. I need to make sure at each step that I am doing the right thing. So, I though i would make sure to see 100% each time I download a config file and then only proceed
