OUTFILE="$OUTDIR/first-passes.pdf"

# Create the directory (ignore if already exitsing):
mkdir -p $OUTDIR

# Iterate through the PDF files and print the last page to our document
find . -maxdepth 1 -name "*.pdf" | while read fname ; do
  echo "Working: $fname";
  pdftk $fname cat r1 output $OUTDIR/first-pass-$(basename $fname);

# merge all those PDFs together
pdftk $OUTDIR/*.pdf cat output $OUTFILE

# Delete all those extra pdfs if you don't want them:
