dot_clean:tldr:16d77

The command "dot_clean -n ${path-to-directory}" is used in macOS to clean up the hidden metadata files (such as .DS_Store) in a directory.

Here's a breakdown of the command:

• "dot_clean" is the actual command to clean up the hidden files.
• "-n" is an optional flag. When used, it performs a dry run, meaning it will show a list of the files that would be deleted without actually performing the clean-up. This is useful for checking what files would be affected before running the command without the "-n" flag.
• "${path-to-directory}" is a placeholder that should be replaced with the actual path to the directory you want to clean up. This is where you specify the directory whose hidden files you want to remove.

By running this command, macOS will scan the specified directory and its subdirectories for any hidden files and remove them, reducing clutter and improving system performance.
