Joining PDFs with Ghostscript
If you need to join together a large amount of PDF files, but don't particularly want to pay for Acrobat Pro, Ghostscript can do the same.
First, download Ghostscript, then build it in the usual manner:
tar xjf ghostscript-xxx.tar.bz2
cd ghostscript-xxx
./configure --prefix=/usr/local
make
sudo make install
Then you can join multiple PDF files like this:
gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=output.pdf input1.pdf input2.pdf
