The command you provided is related to the "fswebcam" utility, which is used for capturing images from a webcam in Linux. Let's break down the command:
- "fswebcam": It is the name of the utility or command-line program you are using.
- "--timestamp": It is a flag or option for the "fswebcam" command. The "--timestamp" option is used to enable the timestamp feature in the captured image.
- "${timestamp}": It is a variable that holds the value of the timestamp. The value could represent the current date and time when the image was captured.
- "${filename}": It is another variable that holds the name of the file you want to save the captured image as (e.g., image.jpg).
Therefore, with the given command, you are instructing "fswebcam" to capture an image from a webcam, include a timestamp in the image, and save it with the specified filename. The value of the "${timestamp}" variable will be replaced with the actual timestamp when the command is executed.
