How to concatenate multiple pdf as one, each input pdf starting on an even page?

问题

DUPLICATE OF How can I merge PDF files (or PS if not possible) such that every file will begin in a odd page?

I have a serie of documents, each one with an unpredictable number of pages.

Say :

• a.pdf (1 page : A1)
• b.pdf (3 pages : B1, B2, B3)
• c.pdf (4 pages : C1, C2, C3, C4)

I want to merge these input files into one out.pdf, that I'll print double-side. Every first page of the input files must be on a front (right) page.

This means the expected result would be

  |A1
--|B1
B2|B3
--|C1
C2|C3
C4|

with "--" being a blank page.

Currently, I'm using pdftk cat.

There seem to be a solution through heavy scripting, using :

# Get number of pages
pdftk x.pdf dump_data | grep "NumberOfPages"
# If the number of pages is odd, add a blank page to x.pdf
# Loop
# Cat the whole

I was wondering if there might be a more simple an elegant solution ?

For example, is it possible to add page-breaks at the begining of each file ?

Thanks in advance

This can be done with pdfjam (which uses TeX; see TeX.SE); the pdfpages package it uses has an option openright which can probably automatically achieve what you want.
