yes sometimes we just miss the simplest things. however take note it still suffers from "argument too long" issues if there are too many directories ( maybe there's a workaround somewhere)
Code:
# ls -p | grep "/" | wc -l
31998
# rm -r */
bash: /bin/rm: Argument list too long
# ls -p|awk '/\/$/&&!/\./' | xargs -i rm -rf "{}"
# ls -p | grep "/" | wc -l
0
