I'd be curious as to the underlying "why?". Having a history of what you've done is generally a Good Thing. The only reason that I personally have ever come across to necessitate not storing my actions is when I'm playing a prank on one of my friends. Other than that, having the ability to go see what commands I was executing three years ago comes in awful handy. I /could/ recreate that arcane command sequence for that one-off job I needed 1,237 days ago, or I could do a history | grep 'substring I remember in command' | less And, if you're worried about the space it takes to store the history, don't. It's extremely negligible.
