I run through the file using an until loop, at the end of each pass I write the last position in the file (using tell()), and the next timestamp to start from, to a text file called gather.dat. This lets it pick back up where is started using seek() first, saves a lot of time, and as long as nothing changes the beginning of the file it moves along just fine.
I like Terry's method for a memery resident scan, may toy with it, mine has to be run every 5 minutes or so, of course you can also write a memory resident perl script that calls the other two on a schedule and run it from something like Firedaemon. As Terry said, there is always more than one way, pick the one that suits you best.

Always more than one way - but here is one possibility: sub tail_log { my $iteration = 0; for (;;) { while (<LOGFILE>) { next unless length; # do some stuff sleep $nap; # dont' forget to check the date to see if we have gone to next day # and if so you have to close and then open new log at end and # so on seek(LOGFILE, 0, 1); } } } hth Terry Fritts --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
