Hello monks!
I have 2 big directories, say BIG_1 and BIG_2 that have 100 subdirectories each. The subdirectories have the same name in both BIG directories, that is BIG_1 contains SMALL_1, SMALL2... SMALL100 and BIG_2 also contains SMALL_1, SMALL2...SMALL100.
What I want to do is to merge the contents of each subdirectory of BIG_1 with BIG_2. That is, if for example SMALL_1 of BIG_1 has doc1, doc2 and doc3 and SMALL_1 of BIG_2 has doc4 and doc5, I want all contents of SMALL_1 of BIG_2 to be moved to SMALL_1 of BIG_1, so that SMALL_1 of BIG1 will finally have doc1, doc2, doc3, doc4 and doc5 and SMALL_1 of BIG_2 will be empty. The same applies to all subdirectories.
