Merge multiple pdf files in one using terminal

Question

I want t convert multiple PDF files into one large PDF file. I've already tried:

convert file1.pdf file2.pdf merged.pdf

but the result wasn't as expected. Is there any way I could do this using the command line.

Answer 1

Install a utility call pdfunite which is a part of poppler-utils:

apt-get update

apt-get install poppler-utils

then use pdfunite to merge the files together:

pdfunite in-1.pdf in-2.pdf in-n.pdf out.pdf
