dd if=file.img of=/dev/sdx bs=4M status=progress

Clearing an SD Card
The following clears the start and the end of an SD Card (or any block device in general).
SD_CARD_DEVICE=/dev/sdX sudo dd if=/dev/zero of=$SD_CARD_DEVICE bs=512 count=1024 sudo dd if=/dev/zero of=$SD_CARD_DEVICE bs=512 seek=$(( $(blockdev --getsz $SD_CARD_DEVICE) - 1024 )) count=1024
