Would be possible to use | tee "${OTP_LOG}" instead of redirection to file, keep the console output and skip the tail process below.

Not sure if it will work, I need the the java PID (see line 68) to terminate the java process later, so if we use tee then I think we get the tee PID instead. I tried something like it, but it did not work. Not sure if I did the exact same thing as you suggested.

[jtorin]

In practice it doesn't matter that much: even if it's the tee pid that is killed, the whole pipe is still terminated.

while true ; do sleep 1 ; date ; done | tee /tmp/log.txt & ; PID=$! ; echo "PID: $PID\n" ; sleep 4 ; ps aux | grep $PID ; kill $PID

Nevermind, it doesn't matter. 🙂

Good tip, I didn't know that. I will leave it as is for now. Do not want to spend more time on it.
