Not really.. that's no better than the free command.

I guess what I'm looking from, roughly, is something like the Used
memory - Cache (from free) + Used Swap - Swapcashed (from /proc/meminfo)

I could get all that info from /proc/meminfo,, of course, but then you
have to subtract to find Used Memory and Used swap.

I find it interesting to comapre that with the Commited_AS value,, for
example, assuming I have the above formula right, my system now is
"using" 1.3 GB of memory, but applications have committed total of 1.78)

I guess I'll just have to write myself a little perl script to parse
meminfo for what I'm looking for.. should be fun.
