Help required change port from 9001 to 9009

[sujitrp]

I know this is a basic question but how can I change the port for frontail ?
on of my docker is using 9001 so I am getting following error.
Solution I can think is change frontail port

`pi@raspberrypi:~ $ frontail /var/log/syslog
events.js:174
throw er; // Unhandled 'error' event
^
