> `root@redacted-prod0:~# watch -n1 ioztat -y -c1`

1.1.0 requires a dataset i.e.

`gnu-watch -n1 ioztat -z -y -c1 august`

I see a flurry of commits since 1.1.0,

There's [plenty more
incoming](https://github.com/jimsalterjrs/ioztat/pull/26) shortly.
Highlights:

* New style that closely resembles zpool-iostat(8)
* Scaling to terminal width (and height in -o mode)
* -e and -H flags for exact values and plain formatting for scripts
* New sort options for IO and throughput (subject to bikeshedding)

Big thanks. Will `-o` become an option on FreeBSD? I saw
<https://github.com/jimsalterjrs/ioztat/pull/20>

Yes, that's what I'm developing it on :)

Should be merging to main soon - testers will be very welcome given so
much has changed.
