Locate Empty Directories from Command Line
As a software engineer that lives too much of his life on a computer, I like keeping my machine as clean as possible. I don't keep rogue downloaded files and removes apps when I don't need them. Part of keeping a clean, performant system is removing empty directories.
To identify empty directories, I use the following command:
