Larry, I'll save you the time. "freedups -a -d /some/dir [/other/dirs]" will look for identical files (the -d requires dates to be equal as well as the content) and hardlink them. It's not terribly efficient, but works marvelously well. Run it from cron once a week or so, perhaps? http://www.stearns.org/freedups/ Cheers, - Bill
