I have a series of folders with employee names and their documents in pdf format. I want to merge and create a single PDF file with pdf documents indexed as bookmarks in pdf file.

I tried using PDFTK to merge the pdf's in folder, however the output does not bookmark.

I created a script for this purpose. You may choose to keep .pdf extension by modify heredoc.

#!/usr/bin/env zsh

pages=1
bookmarks="bookmarks.txt"
tmp_pdf="tmp.pdf"

if [ -f $bookmarks ]; then
    read -p "Do you want to overwrite the bookmarks file? [y/N] " -n 1 -r
    if [[ $REPLY =~ ^[Yy]$ ]]; then
        rm $bookmarks
    else
        echo "Aborting..."
        exit 1
    fi
fi

for pdf in *.pdf; do
    cat <<- EOF >> $bookmarks
    BookmarkBegin
    BookmarkTitle: ${pdf%.pdf}
    BookmarkLevel: 1
    BookmarkPageNumber: $pages
    EOF
    page_number=$(pdftk $pdf dump_data | rg 'NumberOfPages: ' | awk '{print $2}')
    pages=$(($pages + $page_number))
done

pdftk *.pdf cat output $tmp_pdf
pdftk $tmp_pdf update_info $bookmarks output final.pdf

rm -f $tmp_pdf
rm -f $bookmarks

The idea is:

  • Create a pdftk info file which contains bookmark
  • Call pdftk cat to concatenate them
  • Call updateinfo to add bookmarks
  • Remove temp files, done.

  • thank you for your script, i am able to write this bit:tempPDF=`mktemp` for i in *.pdf do bookmarkTitle=`basename "$i" .pdf` bookmarkInfo="BookmarkBegin\nBookmarkTitle: $bookmarkTitle\nBookmarkLevel: 1\nBookmarkPageNumber: 1" pdftk "$i" update_info_utf8 <(echo -en $bookmarkInfo) output $tempPDF verbose mv $tempPDF "$i" done – Bibush GC Jul 18 '22 at 03:36
  • I keep trying to use this script, but I get a `33: parse error near \n`, is there supposed to be more indentation in the `pdf` for loop? – nonreligious Mar 27 '23 at 11:06
  • Actually, I got it to work by removing the indentation for the whole `EOF` block. – nonreligious Mar 27 '23 at 11:49
