Thought of that. According to the man page, vmstat shows, for memory:
avm active virtual pages
fre size of the free list
Does the size of the free list correspond to actual free memory? I
wasn't sure whether that was the case or not.
Also, it's a case of parsing the output from top or parsing the output
from vmstat - I had hoped there would be a simple command that would
show memory state :)
