Clearing auth.log

[hardysummer]

How do I clear my auth.log? It would not allow me to overwrite with nothing (sudo echo "" > /etc/var/auth.log).

Have you thought about using "logrotate" it helps keep your logs in order.

Do this:

sudo bash
cat /dev/null > /etc/var/auth.log

Then ctrl-d or exit to exit.
