Ghostscript gives you the power to combine files, convert files, and much more, all from the command line. It is easy to combine several input files into one combined PDF using Ghostscript: gs -sDEVICE=pdfwrite \ -dNOPAUSE -dBATCH -dSAFER \ -sOutputFile=combined.pdf \ first.pdf \ second.pdf \ third.pdf [...] Your input files don't even need to be PDF files. You can also use PostScript or EPS files
