Changing PDF Metadata on Ubuntu
I found myself in the position where I needed to change the meta-data of PDF files. It comes in really handy when you have an e-reader. While researching how I could change PDF meta-data, I came across a Linux program called PDFTK. I wanted to go over some basic commands (mainly so that I can find them easily).
sudo apt-get install pdftk
Edit Existing Meta-Data:
pdftk book.pdf dump_data output report.txt
You can then edit the data in report.txt which we can later upload back to the pdf. The text file will contain key value pairs like:
InfoKey: Title InfoValue: Coders At Work InfoKey: Author InfoValue: Peter Seivel InfoKey: Subject InfoValue: Programming
After you edit this file, you can update the new meta-data to the pdf.
Update PDF Meta-Data:
pdftk book.pdf update_info report.txt output bookcopy.pdf
