imagine writing a script to run as a daemon reading data off the bottom of a
log file that gets updated every few minutes and processing each new log
line as they arrive.
i could exec("tail $logfile", $lines, $status) every now and then. or poll
the file mtime and run exec("tail $logfile", $lines, $status) when it
changes. there will be some lag due to the polling interval.
but it would be nice to not have to poll the file and somehow trigger the
processing of the new line when the log file is written. but i'm not sure
how to do that.
any ideas?
