Then you can be absolutely certain. I agree - if the file isn't excessively large and appears to be the same length as an existing file, has matching digest/cksum/whatever checks you make and the frequency of these checks isn't that great, you can always do an actual file comparison as the last resort to prove duplicity or not and be 100% sure. The number of times you get through all the checks and actually have to compare the files should be minuscule. _______________________________________________ ActivePerl mailing list [email protected] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
