wacaw:tldr:a750c
The command "wacaw" refers to a software tool or program that can capture video with a webcam.
In this specific command, it is specifying the use of the "--video" option followed by "${filename}". Here, "${filename}" is a placeholder that should be replaced with an actual filename of your choice (e.g., video.mp4). This option tells the program where to save the captured video file.
The "--duration" option is used to set the duration of the video capture. In this case, it is set to "${10}". Again, "${10}" is a placeholder that should be replaced with the desired duration in seconds (e.g., 60 for a 1-minute video).
So when you run this command with the appropriate values filled in, the program "wacaw" will capture video from your webcam and save it to the specified filename, with the specified duration.
