The command you mentioned is for using the "pngquant" program to compress PNG images.
Here is the breakdown of the command:
- "pngquant": It is the name of the program that is being executed.
- "--quality ${0-100}": This flag specifies the desired quality of the output image. The "${0-100}" syntax here indicates that the value can range from 0 to 100. Quality 0 represents the highest compression (smallest file size but lower quality), while quality 100 means the least compression (largest file size but highest quality).
- "${filename.png}": This is a placeholder for the input PNG file name (e.g., image.png). You need to replace this placeholder with the actual file name or path to the PNG image file that you want to compress.
Overall, this command compresses the specified PNG image file using pngquant and adjusts its output quality based on the value you provide.
