Shell Runner is a utility designed to help design and test batch files and command scripts. It displays the output of the command in a window, optionally with a time stamp, clearly marking error output in red. A combined output/error log and/or separate output and error logs can be saved automatically. Once Shell Runner is installed, right-clicking on a file with the extension .cmd, .bat, or .exe will show a new menu item 'Run with Shell Runner'. Clicking this item will start the batch file or executable file using Shell Runner.
