Using nodejs's Forever to output console.logs to screen
You can watch a logfile live by using this shell-command.
tail -f /path/to/logfile
Not sure if this is what you needed.
Directly with forever command :
forever logs app.js -f
It shows in realtime output of your application and forever logs (shows detected changes & restart messages).
Simplest way to go is
Run :
forever logs // will give you list of log files
forever logs 0 -f // then just provide the index of log
