问题
I'm looking for a way to highlight words (e.g."some words [0-9]") or better the whole line with the given words in it, in some onesided PDFs. It will be part of a Batch-process on Windows, so i need a command line way to do this. I've looked at Ghostscript, but can not see how it is to be used.
hope i didnt made something wrong - i looked into other questions, mainly Add comments to PDF files automagically with regular expressions but this helped me not really, also english is not my native language - as you maybe have noticed already.
Thanks in advance
