wacaw:tldr:0387c

This command is using the "wacaw" utility with specific options and arguments.

"wacaw" is a command-line program used to capture images using a webcam in Linux. It allows you to control various parameters of image capture.

Here's the breakdown of the command:

• "wacaw": This is the name of the command or utility being executed.
• "--width ${width}": This is an option to set the width of the captured image. The value of ${width} is a placeholder that needs to be replaced with an actual value, depending on the context or script using this command.
• "--height ${100}": This option sets the height of the captured image. Similarly, ${100} is a placeholder that can be replaced with a desired value.
• "${filename}": This is an argument that tells the utility the filename or path where the captured image should be saved. Like the placeholders above, ${filename} should be replaced with the desired filename (including the extension) and path.

Overall, this command is meant to capture an image using a webcam with specified width and height, and save it to the specified filename/location.
