Secure delete logs in Mac OS X

Question

Securely erasing data from OS X is easy. But is there a way to securely erase all logfiles (including the system logs contained in some database) without actually messing the system up?

Answer 1

Can't vouch as to whether this will muck up Mac OS X, but to securely delete the system logs, try this from command line:

sudo rm -P /var/log/*

(Mac OS X comes with the -P flag for rm which overwrites data 3 times - similar to shred IIRC)
