The command you provided is using the "sips" command-line tool to resize an image file using specific height and width dimensions.

Here is what each part of the command does:

• "sips" is a built-in command-line tool on macOS that stands for "scriptable image processing system." It is primarily used for manipulating and processing image files.
• "--resampleHeightWidth" is an option flag used to instruct the "sips" tool to resize an image based on height and width dimensions.
• "${1920}" is a placeholder, representing the desired width in pixels for the resized image. You can replace this value with the actual width you want.
• "${300}" is another placeholder, representing the desired height in pixels for the resized image. You can replace this value with the actual height you want.
• "${image_file-ext}" is a placeholder for the input image file path and its extension. You need to replace this placeholder with the actual path and filename of the image file you want to resize. Make sure to keep the file extension intact.

To use this command, replace the placeholders with appropriate values and execute it in the terminal. It will resize the specified image to the given height and width dimensions.
