truncate Rails development/test logs

In rails applications development.log and test.log like to grow forever, which takes up space and makes them slow to grep. If I just delete them running processes with logs open might get confused. So I can use truncate instead:

truncate ~/www/*/log/*.log

Even easier, ask cron to do it for me every night:

4 22 * * * * truncate -s 0k  ~/www/*/log/*.log
