Make tar of most recent directories

I have a tree of directories, and I would like to archive the most recent directory at the last level (i.e, of the directories that don't contain subdirectories). Alternatively, I can rm the older directories and tar what's left. Maybe a picture would help:

Code:



                      d1



          d2                    d3



    d4        d5        d6          d7

I want to archive whichever of d4 or d5 is more recent, and whichever of d6 and d7 is more recent. I don't care about d2 vs d3 or d4 vs d7.

I assumed some brilliant pattern to find would do this, but if so it is far beyond my newbie skills.

Code:

 tar cvzf new_dir.tar.gz `find -type d -mindepth 3 -maxdepth 3 -exec ls -ld --time-style=long-iso {} \; | sort -g -k 6,7 | tail -n 1 | awk '{print $8}'`

:}

It's a bit of a mouthfull but should work ;)

Cheers,
Tink
