I have two folders.
A is an older version of B, having been copied at some point.
There may be changes in A but that are not in B.

I wanna find out if there are any, and what they are if they exist.

How do i do that, preferably using Linux standard utils

@4censord that’s a tricky question
you just want to know what’s missing or updating state from A and B?
@hypha i want to integrate changes that have been done in A into B,
but selectivly
because there are changes i dont care about, but i dont know which ones yet
@4censord hmmm
what is a change? a missing file or the content has change?
@hypha both :/
@4censord hmmm
as far as i know there is no interactive way of doing this
the silly way i would suggest is using git repo (one for A and another for B) and doing merges (with conflicts to solve), having the other as remote to the other
