Something like 'free' from unix and not vm_stat so that I can get simple free and used memory totals in MB? Any other suggestions? Thanks.

Code:
top -l 1 -n 0

.. and then use the usual methods of getting the exact bits you want (grep, awk, perl, etc...)

But all the usual caveats about knowing what they really mean (that can be non-obvious) apply.

Great. Didn't think of Top... Is it as accurate as a 'free'? I'd heard rumors and was wondering. Right now I'm using a long winded vm_stat configuration.

What *exactly* are you looking for. Different methods will give you different results because there are subtle differences in what they are exactly telling you. If you are simply reporting this back to the user... well at least this number will be somewhat consistent with other methods they might be looking at.

I'll use this. Thanks for the comments, it's appreciated.
