The given command is used to copy the contents of a source image file to a destination block device.

Here is a breakdown of each element in the command:

bmaptool: This is the name of the command-line tool being executed. It refers to a utility called "bmaptool", which is used for manipulating images with Bmap format.
copy: This is a subcommand of the bmaptool utility indicating that it should perform a copy operation.
--nobmap: This is an option used in conjunction with the copy operation. It tells bmaptool to not create or use a Bmap file for the destination block device.
${source-img}: This is a placeholder for the path or filename of the source image file. You need to replace ${source-img} with the actual path or filename of the image file you want to copy.
${-dev-sdb}: This is a placeholder for the designation of the destination block device. You need to replace ${-dev-sdb} with the actual designation of the block device you want to copy the image to.

In summary, the command is instructing the bmaptool utility to copy the contents of the source image file to the specified destination block device, while skipping the use of a Bmap file.
