Well, uh, there's your problem.
I use
jhead as part of the script I run to copy the files from my SD cards (it also makes automatic backups). (Jhead doesn't work on RAW, of course, so you'd have to use exiftool or something for that.) First I extract the cameramodel into the variable $cameramodel (using awk) and then
run "jhead -autorot -nf%Y%m%d-$cameramodel-%f" on each file. This preserves the original filename (%f), and prepends the date and camera model.
