Maybe you want to open the file as a pipe from tail -f. Something
like:
open LOG, "tail -f </var/log/syslog |" or
die "Couldn't open log file";
Then maybe you work up a couple loops that check the input stream.
for (;;) {
while (<LOG>) {
$quit = myprocess $_; # process the line...
}
last if $quit;
sleep 5; # or some length of time
}
You might check the tail man page for other options that could be
useful.
