-D means to delete All snapshots of given pool.
-d and -F 1d means to delete all snapshot older than 1 day
Currenty there is no way to delete snapshot of given pool that are older by specified time. I suppose this should be implemented.
You can either delete ALL snapshot of given pool. Or delete all snapshots of all pools that are older then specified time (or ttl).

I agree that this should be implemented, but actually making the change has some pretty big implications. I'm not so sure what is the best method of doing this. In no particular order:
-
Currently, zfSnap can both delete and create snapshots in the same invocation. Change the behavior so that "create" is the default mode and using -d or -F switches to "delete" mode. -d and -F can remain in general options, but any zpools/zvols defined will be checked for deleting rather than snapshotted. This breaks current behavior.
-
Simply add two new flags to the "pool options" that mimic the behavior of -d and -F, and deprecate -d and -F. This is the most conservative approach and doesn't break anything, but -d and -F are so intuitive, I can't think of other intuitive flags for these operations. -D is already used, so we can't simply capitalize.
-
Migrate -d and -F from "general options" to "pool options." Also create a "snapshotting flag" (say -c, for create). These would behave the same as the other pool options, where the "create" mode or "delete" mode would remain in effect for all subsequent zpools until overridden. This would be a major syntax change and would break current behavior.
I personally don't like that zfSnap currently implies the creation of snapshots. The mode is never actively declared, and when delete mode is declared, it still creates a snapshot on any zpool passed as an argument. I personally prefer options 1 or 3. It solves this feature request and makes the behavior of zfSnap more explicit.
Thoughts?

Or we could rewrite zfsnap to support human readable commands like:
zfSnap snap ...
zfSnap delete ...
This will break syntax, but that doesn't bother me too much.
This however would open door for other functionality that can be lated added
For example #20 may as well become
zfSnap send .... or something like that

I like that approach, of using human readable commands. When the syntax changes, just bump to version 2.
So, zfSnap would have distinct modes. snap, delete, send, etc. No mixing and matching modes in the same call. How does that sound?

Sounds good to me.
