Shows updated status in a terminal window for connections to port '80' in a human-friendly form. Use 'watch -n1' to update every second, and 'watch -d' to highlight changes between updates.

If you wish for status updates on a port other than '80', always remember to put a space afterwards so that ":80" will not match ":8080".

watch lsof -i :80

netstat already has '-c' option for continuous (once-per-second) output. You can pipe the output to grep, no need for subshells. zolden has the right idea: for human-readable status updates, use /usr/bin/watch.

Furthermore, 'grep 80' will also match ports 8000 and 8080, process IDs 80 and 800, and any IP address with '.80' in it.
