Looks like the wiki stripped some formatting.
I still don't know that this is doing anything meaningful in the context
of ZFS memory use.

I understood it to just be showing a summary of kernel memory
utilization, no specific zfs stuff (which I guess could be got from
vmstat -z although I dont understand those statistics well enough to do
this myself.) Semi useful in a peripheral way maybe.

That is surely the intention, but I am not convinced it is doing what it
says on the box :)

The script is nonsense, it's not valid sh syntax. I guess it got badly
mangled by the wiki software.
