Really? So constantly piping the results of a log file through a
function to sort the data is not the best method of giving real time
data based on the piped output of a log file?

so could I see an example?
open(LOG, "tail -f /var/log/messages |");
while (<LOG>) {
if (/something important/) {
print "Found something...\n";
}
}
close LOG; # Never get here, but for completeness...
I'm not sure what you mean by sorting the output. Since there is
continuous input, there will be continuous output. You could sort and
display aggregated output at intervals rather than having a real-time
output stream.
