How to flush the DNS Cache on OSX

I keep forgetting this one hence writing it up. Every so often you need to flush the local dns cache – usually you’ve made a change in some dns & you want to test it immediately etc.

dscacheutil -flushcache

It’s that simple – so simple it’s an easy one to forget 😦
