All the photos were taken on the same camera and the common thread is the date and time although some were resized (for email) the originals could be identified by there size. John On Mon, 2010-03-08 at 20:33 +1300, Bruce Kingsbury wrote:
I had a script to do this a while back; used find, md5sum and sort, produced a list of all the files where there was more than one with an identical md5sum, and optionally deleted all but one automatically. That was always a bit of a risky option! Also never got around to making it the oldest one, or the one with the most sensible-looking filename or anything. It was pretty random about which one it chose to keep.
I can't find the script now but I could probably hack something up again if nobody knows of any better tools.
