mogrify: Convert all PNGs in the directory to JPEG.

mogrify

$ mogrify -format ${jpg} ${*-png}

try on your machine

The command you provided, "mogrify -format ${jpg} ${*-png}," is used to convert image file formats using the "mogrify" tool, typically found in the ImageMagick software suite.

Let's break down the different parts:

"mogrify": This is the command used to modify or transform an image file.
"-format ${jpg}": This option specifies the desired output format for the image. In this case, the output format is specified dynamically using the value of the "jpg" variable. The format can be any supported image format, such as "jpg", "png", "gif", etc.
"${-png}": This represents a wildcard filename argument that refers to all files in the current directory with names ending in "-png". The "" is a wildcard character that matches any characters in the filename, and "-png" specifies files ending in "-png". Note that this assumes you are running the command in a directory with the relevant files.

In summary, the provided command will convert all image files in the current directory that end with "-png" into the format specified by the value of the "jpg" variable. However, it seems like the variable definition is missing in the command you provided.
