From older times (Mac OS 10.4) I had found this command line on the web somewhere:
mdfind '(kMDItemFSContentChangeDate >= $time.now(-60)) && (kMDItemFSContentChangeDate <= $time.now)'
it gave me a list of files that where changed in the last minute. This does not work anymore on Mac OS 10.6. Can anybody explain why this doesn't work? And even suggest a working command line?
