Okay, I got a script to work, but it does something strange. It converts the files from tif to jpg, but it makes 2 copies, 1 is the normal size and the other is a smaller version of which I don't need. I'm just learning scripting, and I have poured over this script for hours trying to figure out why this is happening. The script is as follows: #!/bin/sh mkdir old for filename in *.TIF; do case $filename in *.TIF ) infilename=$filename outfilename=${filename%.jpg}.jpg convert $infilename R$outfilename mv $infilename old;; * ) echo "error: $filename not a TIF file." ;; esac done After it completes, the files are named: DSCF0089.TIF.jpg Is there a utility something I can use to do a mass rename by stripping the .tif extension? I have looked around but haven't had much luck. TIA! Dan
