Sure, it's a workaround for vmstat -z, but not easy for vmstat -m
which has no handy colons/commas to key from.
Shouldn't stats be easy to parse in order to be useful to many
rather than a test of a few users script fu ? :)
So why not hunt up, check for potential new collisions to fix and
change the strings in a lint run? See below...
Thank you for pointing out that I had to do 'size * (used + free)',
not just 'used'. And for the fu tips too :) I guess 'free' are not
returned to the system for other uses then.
Are there detailed docs on what all the fields mean in the various
tools... vmstat -z/-m, systat -vm, netstat -m, top, ps. Most docs
seem to just list the field names a command line switch will display,
instead what sense to make of them.
/me, grokking with wild abandon...
