This means you need to delete the deepest paths first, and work backwards. But now that they are removed, Folder2 is empty as well. It would be easy to find EmptyFolder1, and EmptyFolder2. Sent it off to Steve to try, and when he emailed me back I realized how tough of a problem this is.įor example, if you were looking to remove empty directories from this structure: In my arrogance I thought this would be such an easy task, and coded a utility in less than an hour.

I am old-school, having started as a UNIX system programmer some … 40 years ago:-) So, I like elegant solutions, and in UNIX, this would be a simple one-line piped solution … unfortunately, I’ve been stuck on Windows for the past few decades…I’m wondering if you’ve ever tackled this, and, if so, if there’s anything you can share?” I have found all sorts of approaches to this, but none are elegant.

“…I want to round out this junk cleaning by trashing empty directories as well.

If the directory doesn’t exist we simply return that the directory that doesn’t exist using the echo command.A few months ago I received an email from Steve in Ontario:.

echo is used to display things on the screen.

After that, we are displaying that the files have been successfully deleted using the echo command.

We do the same until there is no file with zero sizes. file with zero-sized), using -delete argument we will delete that particular file from that directory.

If the directory exists then we are going to use the looping statement (for loop) to iterate over files and check their size using -size 0, as soon as we found a file that meets our requirements (i.e.

First, we have to take the directory name as input from the user using the read command and store it in variable directory_name.

# Or if directory doesn't exists it will printĮcho 'Zero-sized files are Successfully deleted' # Taking directory name as input from user

If the directory doesn’t exist we are going to display the directory that doesn’t exist.

echo is just like a print statement it is used to display things on the screen. rm (remove) is used to delete the files/folder.

If the directory exists then we are going to use the looping statement ( for loop) to iterate over files and check their size using -size 0, if the file is zero-sized then we enter the loop and remove the file using the rm command.

Here we are using if statement with the -d flag it will return true if the directory exists.

To check if the directory name entered by the user really exists, we are using the if statement.

Firstly we are taking the directory name as input from the user using the read command.

Use for loop to traverse each file and check their size.

Input directory name and check if the directory exists in the current folder/directory.
