dd: Generate a system backup into an IMG file and show the progress.

$ dd if=/dev/${drive_device} of=${filename-img} status=progress

try on your machine

This command is using the "dd" utility in Linux to perform a data transfer operation. Here is what each part of the command does:

"dd": This is the command itself, invoking the "dd" utility.
"if=/dev/${drive_device}": The "if" flag specifies the input file or device for the data transfer. In this case, "/dev/${drive_device}" is the input device, where '${drive_device}' should be replaced with the appropriate drive device name (e.g., /dev/sda).
"of=${filename-img}": The "of" flag specifies the output file or device for the data transfer. In this case, "${filename-img}" is the output file, where '${filename-img}' should be replaced with the desired filename and file format, such as "example.img".
"status=progress": This flag is used to display the progress/status of the data transfer operation in text format. It provides information on the amount of data transferred, the transfer rate, and the estimated time remaining.

Overall, this command is used to copy the contents of a device (specified by the 'drive_device') to a file (specified by 'filename-img') while showing the progress of the operation.
