Given a dir containing several tif files, write a bash script that produces a single pdf file. You can use gs or imagemagick convert (convert uses gs on the backend, so you should better use gs) I can do it but the produced pdf is very large usually. If you open Acrobat in windows, then choose "create pdf from files", it creates a small sized pdf without data loss. Do the same on Linux.
