convert:tldr:b0d72
The given command is written in a syntax that is commonly used in shell scripting languages like Bash.
In this command, convert is a command-line tool used to convert images from one format to another. It is likely referring to the ImageMagick's convert utility.
${image-jpg} and ${image-png} are placeholders for actual image filenames, where the suffix -jpg and -png suggest that the command expects a JPG (or JPEG) image file as the input and a PNG image file as the output.
To execute this command, you would replace ${image-jpg} with the actual filename of the JPG image you want to convert, and ${image-png} with the desired filename for the resulting PNG image. Once substituted, the command could look something like:
convert image.jpg image.png
This would instruct the convert utility to convert the image.jpg file from JPG format to PNG format and save it as image.png.
