Cropping a PDF / Adding crop box using Ghostscript

I have a few hundred PDFs that I need to crop - I'm willing to either crop the actual documents or simply add a crop box to e开发者_JAVA百科ach so the correct viewable area shows when the PDF is opened.

How can I do this using Ghostscript (v8.71)? I found this:

gs -sDEVICE=pdfwrite -sOutputFile=marked.pdf [/CropBox [54 54 1314 810] /PAGES pdfmark original.pdf

I've tried this (and all variants I can think of) but I always get an error such as this:

Error: /undefinedfilename in ([/CropBox)

I've tried moving around the parameters of the command but nothing seems to work. Does anyone know how this can be accomplished?

Update: Still no crop box after correcting syntax, see results -

You are on the right track, trying to use pdfmark/Ghostscript for adding a CropBox. But your syntax isn't 100% correct.

Try this instead:

 gs \
  -sDEVICE=pdfwrite \
  -o marked.pdf \
  -c "[/CropBox [54 54 1314 810] /PAGES pdfmark" \
  -f original.pdf
