I'm used to typing free -m in ubuntu to see how much memory is available, in MB. What's the equivalent command in Mac OSX?

Since OS X is BSD-based, your best bet will be using sysctl to get the information you need.

sysctl -a | awk '/hw./' && '/mem/'

You could also try this:

Thanks, that's close, the other question has some good suggestions. – jimbojw Dec 19 '12 at 20:53

should be :

sysctl -a | awk '/hw./' && '/mem/'  

(note the '/mem/')

then run the output through egrep (depending upon what is desired).

There are some perl scripts too - on the net.
