Comment: unison is bi-directional (Score 1) 153

unison has already been suggested multiple times.

I used unison. It's perfect to sync from A to B (it only syncs the diffs) then modify B and later sync B to A
You also can modify A and B at the same time as long as it's not the same file, then sync and then A and B are identical.
You can even sync in cycles: A->B->C->A with modifications on all three directory trees and it still works
Unison also handles deletions on both sides fine.
Hint: use the -group -owner -times flags

Comment: reverse the priorities (Score 1) 304

1=lowest
2=medium
3=high

If there is over 20% at level 3, just add one level, so you get this:
1=lowest
2=medium
3=hich
4=top

And in some years the top priority will be at level 10 etc...
That way you will never have 50% of high, and never have to purge the list to start from scratch.

several space projects have failed because of blocked fuel lines or similar problems due to forgotten items.
Can't they "simply" test the full operation of the sattelite, including the engine, before mounting it on the rocket?
Othe solutin would be to have every item, even rugs, fitted with serial numbers and rfid chips so you can easily and fast account of the whereabouts (or not) of everything.
