Port Detection

If you just want to detect which port your program started listening on, you can do this with the tuna detect command. A time is allocated for detection, by default 5 seconds, but this behavior can be defined using the --seconds flag or the TUNA_DETECT_SECONDS environment variable. After this period expires, tuna will terminate along with all child processes.

Example run:

tuna detect -- nc -l 23554

Example output:

tuna detect -- nc -l 23554
