This is highly dependent on the frequency with which you run the script, the number of files, possibly the size of the files, etc. cron in itself is going to be running anyways (most likely) having it fire up a single process to remove some files isn't terribly slow, until you are talking about large amounts of files or you run it very often like every couple of seconds. So the question becomes how long "may" a file stay out there, because this determines how frequently you must run the script, in other words, if a file has not been accessed in five minutes but must be deleted before it is stale for 6 minutes then you have to run the script every 59 seconds. etc. If you must take this approach and are on a unix system, I would avoid a Perl script and install a recent version of 'find' and use 'rm' instead. That should speed up the file location and removal without the overhead of the perl interpreter being fired up. http://danconia.org http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
