Copying / Pasting Metadata to another pdf document

[SungDripWoo]

Hey im fresh out the box with this software dont know anything about coding Im trying to copy the exact same meta data from one pdf file to the other how is this possible if anyone could walk me through?

The basic command would be
exiftool -TagsFromFile /path/to/source.pdf -All:all /path/to/target.pdf

But there are a few issues to note of. Any edits exiftool makes to a PDF are reversible. Also, a lot of PDF programs add custom data which exiftool might not be able to copy.

There are other PDF programs, command line and with GUIs, that can copy PDF data and are better suited. A couple exampels are pdftk, qpdf, and pdfgear
