I would like to add an existing PDF file to another existing PDF file after a given page and not necessarily at the end of the file. How can I do this in Linux without degrading the quality of the PDF file?
To be clear, my scenario is this: I got PDF file, called file_2.pdf, which I would like to add to another PDF file, called file_1.pdf. The file file_1.pdf has got, let's say, 100 pages and the file file_2.pdf is made up of three pages named a, b and c. I would like to add file_2.pdf after page 35 of file_1.pdf, so that the resulting file's pages are in this order: 1, 2, 3, ..., 32, 33, 34, 35, a, b, c, 36, 37, 38, 39, ..., 98, 99, 100.
It is very important for me that the resulting file not lose any quality in the process.
