joining multiple PDFs into one

[Russell Reiter]

Someone else had posted that: cat file1.pdf > out.pdf cat file2.pdf
>>out.pdf cat file3.pdf>>out.pdf worked and they were able to see all
three PDF pages. Before anyone jumps on this I know this is not the
same as the following.

cat file1.pdf file2.pdf file3.pdf>out.pdf did not work, even though
the man page says it should. I see only two possibilities, your
environment changed the way cat works or your pdf parser couldn't do
what the parser of the person who had success viewing the document
could do, and that is deal with the multiple headers and eof
characters in the resulting single document.
