The command pngcheck -vc ${filename-png} is used to verify and check the integrity of a PNG (Portable Network Graphics) image file.

Here is the breakdown of the command:

pngcheck: This is the command-line tool used to check PNG files. It analyzes the structure, data, and metadata of PNG images.
-vc: These are options or flags provided to the pngcheck command.
- -v stands for "verbose" mode. It provides a detailed report of the image, including informational messages and warnings.
- -c stands for "complete" checking. It performs a thorough verification of the PNG file, checking both the image data and the associated metadata.
${filename-png}: This is a placeholder that represents the actual filename and extension of the PNG image file you want to check. You need to replace ${filename-png} with the actual filename and extension of your image file. For example, if the image file is named "image.png", you would replace ${filename-png} with image.png.

After replacing ${filename-png} with the actual filename, the command will verify the given PNG image file, providing a detailed report on its structure, data, and metadata.
