This question already has an answer here:
I created a directory somewhere with permissions
rwxrwxr-x so that other users in my group can create files and directories in it.
I do need to be able to delete the contents in this "public" directory, but it seems that while I am able to remove any files in this directory I cannot remove and subdirectories under it.
Is there a way to remove such subdirectories owned by others under a directory owned by me?
