I chose to ignore for a reason.
Have you ever ran a batch file? You can double-click on it in windows, it will open up an MS-DOS prompt, execute the file, and then close the prompt. It does this fast because .bat files are very fast to read and execute, typically.
With all that said, when you double clicked on it the first time, it did its thing and is now working. If you want to see if it said anything after in the DOS prompt, open up your Command Prompt, navigate it to whatever folder you put the .bat file, and then type in its name. The DOS prompt won't close immediately following the running of the file.
