Thanks @ilkkachu : "you don't need all leaves (from all directories) first?" - you know what, turns out I don't really ; didn't think about that at all :) This answer works grep for the OP Q example; for my A example (where the root node might be the only instance having the "needle" substring) I get a mv: cannot move ‘./someotherdir’ to a subdirectory of itself, warning, but it does what it should. Thanks again!

@sdaau, ah of course, the replacement doesn't change anything if the keyword isn't there, so it's useless to try to rename. Ok, we could add a test inside the shell snippet, or just add a filter on the find... (edited)
