Hi.
You can try using IO.popen (`ri IO.popen` from the command line) or try installing the win32-open3 gem, which allows you to easily pipe standard input, standard output and standard error into separate I/O pipes.

Maybe this works for you:
output = `start
E:\\TradingTools\\IBController\\IBControllerStart_customised.bat`

Note the " ` ", it's a backtic, not a single quote (" ' ").
