Use GNU find to show only the leaf directories

Question

I\'m trying to use GNU find to find only the directories that contain no other directories, but may or may not contain regular files.

My best guess so far has been:

Answer 1

This awk/sort pipe works a bit better than the one originally proposed in this answer, but is heavily based on it :) It will work more reliably regardless of whether the path contains regex special characters or not:

find . -type d | sort -r | awk 'index(a,$0)!=1{a=$0;print}' | sort

Remember that awk strings are 1-indexed instead of 0-indexed, which might be strange if you're used to working with C-based languages.

If the index of the current line in the previous line is 1 (i.e. it starts with it) then we skip it, which works just like the match of "^"$0.
