This command is used to open an image file using the Viewnior image viewer in fullscreen mode.

Here's a breakdown of each part of the command:

• viewnior: This is the command to launch the Viewnior image viewer.
• --fullscreen: This option tells Viewnior to open the specified image in fullscreen mode. This means that the image will be displayed without any window borders or menus, taking up the entire screen.
• ${path-to-image-ext}: This placeholder is where you should replace it with the actual path to the image file you want to open. The ${path-to-image-ext} suggests that you should provide the full path and name of the image file, including the file extension (such as .jpg, .png, etc.).

For example, if you have an image named "example.jpg" located in the /home/user/images directory, you would replace ${path-to-image-ext} with /home/user/images/example.jpg, resulting in the command:

viewnior --fullscreen /home/user/images/example.jpg

Executing this command will open Viewnior in fullscreen mode with the specified image displayed.
