in thread How to compare 3 lists

The actual output looks like -

NAME tank/filesystem@hourly-1348093078_2012. tank/filesystem@hourly-1348093078_2012. tank/filesystem@hourly-1348093078_2012. tank/filesystem@hourly-1348093078_2012. tank/filesystem@hourly-1348093078_2012.

They are auto-created every hour and the command outputs them in date order (I can choose earliest or latest first), so using your example I would need to split on the '.' and pick up the date and hour I think

    Ok, then my approach is of no use in your case. Please use roboticus solution. I don't understand now how do you find snapshots 1-6. Are those the first 6 entries on master? So you could think about not scanning whole files, only 6 entries of master and as many from slaves as needed (date check) - in case the files are huge.

      Thanks for your time, I'll go ahead with the other solution, and feed back if that would be useful.

[GrandFather]: However, by the end of the day I had discovered its deceptions and now have it working correctly, so yes, all's well that ends well. :-D
[Corion]: GrandFather: Ah, (hardware) APIs - I have a similar situation with Chrome and its API... It is fairly underdocumented and I guess I have to hunt...
[Corion]: ... down supposedly working code to find out what I'm supposed to do
[GrandFather]: I haven't any "working code" to inspect! I have to find ways to generate reference signals then check the numbers I get at the far end match.
