The command "feh --cycle-once ${path-to-images}" is used to cycle through multiple images in the specified directory once in the feh image viewer.

Let's break down the command:

• "feh" is the command to launch the feh image viewer.
• "--cycle-once" is an option that tells feh to cycle through the images in the specified directory only once.
• "${path-to-images}" is the placeholder for the actual path to the directory containing the images. You need to replace this placeholder with the actual path to your images.

When you run this command, feh will open and display the first image in the specified directory. It will then automatically cycle through the subsequent images in the directory one by one until it reaches the end. Once it reaches the end, feh will close automatically.
