## Combine multiple PDF files

It's also possible to insert a pdf file into another. For example, I had to insert one page from a pdf file after page 2 of another pdf file. This is how it's done:
pdftk A=file1.pdf B=file2.pdf cat A1-2 B1 A2-end output combined.pdf verbose
So the output results in pages 1,2 from A followed by page 1 from B and then the rest of A.
