How to redirect the stdout and stderr in rolling file with Unix redirection

Question

I have java application which I am running on Unix from the command prompt. I am redirecting stdout and stderr to console.out and console.err files

Answer 1

Pipe the result to split like this:

java MyAppName | split -b500k - Console.log

This will create a new file every time you go over 500k. See the man-page for split for more details and options.

Answer 2

Or you can use rotatelogs

nohup java MyAppName 2>&1 | rotatelogs -l Console_%Y-%m-%d.log 86400 &

This will create a new file with today's date every day
