Try:

I hate to sound ungrateful; but what you suggest I try is something that
I listed in my message as having *already* tried.
Still down there in the quotes, you can see it. I listed two ways to
get a superset of what I wanted, and pointed out that grep would then
let you whittle it down, so I can make my script work.
I'm still looking for a cleaner way, because it seems like a weird thing
not to be able to get directly from zfs list. A solution was proposed
to me in email that works in later versions, but wasn't in OpenSolaris
2009.06: use the -d switch and set recursion to 1 level. That seems
like it will work, when a stable version including that option is
released. I'll note it in my code for use then.

I thought this was simple. Turns out not to be.
bash-3.2$ zfs list -t snapshot zp1
cannot open 'zp1': operation not applicable to datasets of this type
Fails equally on all the variants of pool name that I've tried,
including "zp1/" and "zp1/@" and such.
You can do "zfs list -t snapshot" and get a list of all snapshots in all
pools. You can do "zfs list -r -t snapshot zp1" and get a recursive list
of snapshots in zp1. But you can't, with any options I've tried, get a
list of top-level snapshots in a given pool. (It's easy, of course, with
grep, to get the bigger list and then filter out the subset you want).
Am I missing something? Has this been added after snv_111b?
