Using rbox.execute('....some shell cmd with output....') leads to stty annoyances on ubuntu 12.04 and 14.04 #57

The output of the command contains 'stty: standard input: Inappropriate ioctl for device'

That's annoying and doesnt happen if I use ssh with the same command on the same machines.

Thanks I appreciate input. Happy to accept a pull request that resolves the issue.

Actually I have to real idea how to fix that. I wonder, if others users don't see that problem, too?

I think what happens in the background is that stty is called, which throws that warning, like in this example:

echo foo | ruby -e 'system("stty -echo")' stty: standard input: Inappropriate ioctl for device

Hm, it looks like the line @rye_stty_save = stty -g.chomp rescue nil is causing the issue. I dont see, where #@rye_stty_save in the code is ever used again. Should I simply drop those lines or make it silentby calling 'stty -g 2>/dev/null' ?

BTW: The same issue happens if you make a ssh myserver 'stty -g' , so it might have to do with the particular version of stty.
