Stdout is going to output file

[freb]

When you use a TTY, all of the output channels are merged, so you no longer get separate stderr/stdout:

I think this means that we have a decision to make between:

1. separate stderr/stdout channels
2. interactive stdin

Solutions are to:

1. modify the command to add 2> /dev/null, essentially discarding all stdout, or
2. update the code to not use stdout to local file, but instead support downloading a file on command completion
3. Use sed -i '1d' *.xml to remove the first line from the output files (assuming the hostgroup warning on the first line is the only issue)
