Shell Script para eliminar directorios vacíos en Linux

Este tutorial muestra cómo buscar directorios vacíos y eliminarlos de forma recursiva mediante un script de shell. Si el administrador del sistema no desea mantener los directorios vacíos, este script puede eliminarlos todos rápidamente.

Puede ingresar la ruta donde necesita buscar directorios vacíos. El script confirmará antes de eliminar el directorio vacío.
