Add file path output

[mfrischbutter]

Hello, i am using this script in an automated shell script, so i cant see what input file is used. So i added the path to the error output. I thought it would be also nice to be able to click on the path and get to the input file, because of this i output the realpath. If needed i can disable this by default and add an option to the script.
