The command "pngcheck ${image-png}" is used to run the "pngcheck" tool on a specified PNG image file.

Here is a breakdown of the command:

"pngcheck" is the name of the tool or program that is being executed.
"${image-png}" is a placeholder for the actual PNG image file. The syntax "${...}" usually indicates a variable or parameter. In this case, the command expects you to replace "${image-png}" with the actual filename or path of the PNG image you want to check.

When you run this command with the appropriate image file, the "pngcheck" tool will perform a series of checks and tests on the PNG file. It will analyze the file's structure, metadata, and various other aspects to ensure that the image is valid and follows the PNG file format specifications. The tool will report any issues, errors, or warnings it finds in the image file during the analysis.
