i’m trying to script administrative tasks in windows and i’m really  
not feeling the ruby love, does anyone have some suggestions on a way  
of running commands and catching STDERR in windows?

Try:

1. win32-open3 gem
2. use Kernel#system or `` (backticks) and redirect output to a file  
or pipe. Windows from 2000 up supports stderr  
redirection ( command 2\> err.txt )

when i run this in production it seems to die while trying to read  
from the Output IO object, if its

io\_in, io\_out, io\_err = Open3.popen(‘some command with parameters’)

out = io\_out.read (hangs here forever if the command should have worked)
