The command "img2txt --brightness=${2}" is used to convert an image file into ASCII art with a specified brightness level.

Here's a breakdown of the command:

• "img2txt" is the name of the program or script that performs the image to ASCII art conversion.
• "--brightness" is an option or flag that allows you to specify the brightness level for the ASCII art.
• "${2}" is a placeholder or variable that represents the second argument passed to the command.

When executing the command, you would typically replace "${2}" with an actual value or variable specifying the desired brightness level. For example, if you want to set the brightness to 0.5, you would use: img2txt --brightness=0.5 or if you have a variable named "brightness_level" storing the brightness value, you can use: img2txt --brightness=${brightness_level}

The command essentially instructs the "img2txt" utility to convert the image file into ASCII art, adjusting the brightness according to the specified value. The resulting ASCII art will have its brightness modified based on your input.
