get the following tools
1)pdftk
2)mutool (part of mupdf-tools package)
then I need to rotate it 90 degrees
pdftk in-file.pdf cat 1-endeast output out-file.pdf
this rotated it 90 degrees
Then i needed to split the pdf which had pages 2 on one to one on one:
mutool poster -x 2 input.pdf output.pdf
but sometimes the pages are out of order (even and odd)
so then i can do
pdftk infile.pdf shuffle even odd output outfile.pdf
also useful will be
