I want to delete the top level directory which does not contain any files, but can contain other empty (meaning again not containing files) directories. For example:
$ ls -R .: foo/ ./foo/: bar bar1 ./foo/bar/: ./foo/bar1/:
Here, I would like to delete the directory
foo/ (and its subdirectories).
At first, I thought of using something like
find . -type d -empty for the search, but since foo contains directories, it only finds the lower level ones:
$ find . -type d -empty ./foo/bar ./foo/bar1
I guess I could loop until
find . -type d -empty finds nothing, but I may end up having a very big directory structure containing a lot of those empty directories and I'm concerned about the performance impact of doing it that way...
