On a mac or linux, the output is the same output you would get from running lsof -i :
`
[
'COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME',
'nc 20661 michael 3u IPv4 0x3b190d9d07c2c3db 0t0 TCP *:8017 (LISTEN)',
'nc 21145 michael 3u IPv4 0x3b190d9d054773db 0t0 TCP *:8017 (LISTEN)',
'Python 21221 michael 3u IPv4 0x3b190d9ceb8dfd7b 0t0 UDP localhost:8017'
];
On windows, the output is the same as running netstat.exe -a -n -o | findstr :
[
'TCP 0.0.0.0:9000 0.0.0.0:0 LISTENING 5220',
'TCP 127.0.0.1:9000 127.0.0.1:62376 ESTABLISHED 5220',
'TCP 127.0.0.1:9000 127.0.0.1:62379 ESTABLISHED 5220',
'TCP 127.0.0.1:62288 127.0.0.1:9000 TIME_WAIT 0',
'TCP 127.0.0.1:62299 127.0.0.1:9000 TIME_WAIT 0',
'TCP 127.0.0.1:62376 127.0.0.1:9000 ESTABLISHED 7604',
'TCP 127.0.0.1:62378 127.0.0.1:9000 ESTABLISHED 7604',
