bash script for removing directories NOT containing file type

Rasi · 2009-10-13 07:09:39

i want to have something like this:
check all directories (AND subdirectories) for a certain filetype. If the filetype can NOT be found i want it to delete the the parent.

e.g.:

directory test contains an mp3
directory test2 contains no mp3
directory test3 contains no mp3
directory test3/1/ contains no mp3
directory test3/2/2/ contains no mp3
directory test4/1/2/ contains a mp3

the script should now delete test2 (as it does not contain mp3) and
should delete test3 (since somewhere down in its subfolders there are no mp3s), but
it should NOT delete test1 (has mp3) and
should NOT delete test4 (somewhere in its subfolders is a mp3)

alright.. i have come up with this so far:

find -mindepth 1 -type d |
while read dir; do
    if [ ! -f $dir/*.mp3 ]; then
    rm -fr $dir
    fi
done

this - however - does not work when a mp3 is found somewhere deep in directory structure.

untested...

find -mindepth 1 -type d |
while read dir; do
    if [ $(find $dir -name *.mp3 | wc -l) -eq 0 ]
        rm -fr $dir
    fi
done
