This is essential and really difficult to find answers to, but this guy gave it: http://ludo.qix.it/archive/2005/08/merge-postscript-files.html The keywords I would have liked to see: "merge postscripts into multi-page document" or "combine postscript multiple page" e.g. gs -sDEVICE=pswrite -sOutputFile=output.ps -dNOPAUSE -dBATCH file1.ps file2.ps file3.psorgs -sDEVICE=pswrite -sOutputFile=05358spectra.ps -dNOPAUSE -dEPSFitPage -dBATCH `ls 05358_*.eps`(the added option is to make sure the .eps isn't cropped)
