The command viu -n ${filename} is used to display an image file in the terminal using the program called "viu" in "narrow" mode.

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

• viu: It is the name of the program that is being executed.
• -n: It is a flag or option provided to the viu command. In this case, the -n flag tells viu to display the image in narrow mode, which means it adjusts the image to fit within the terminal width.
• ${filename}: This is a placeholder for the actual filename of the image you want to display. In command line usage, ${filename} is typically replaced with the actual name or path of the target image file.

For example, if you have an image file named "image.jpg" in the current directory, you can execute the command as viu -n image.jpg. The program viu will then open the image in the terminal, adjusting its size to fit within the available width.
