Summary

The dd command stands for (Convert and Copy a file). This utility can be used to convert and copy a file, and most of the time is used to copy a iso file (or any other file) to a USB device (or any other location) to make a ‘Bootlable‘ USB stick.

root@example.com:~# dd if=/home/user/Downloads/debian.iso of=/dev/sdb1 bs=512M; sync

Note: In the above example the usb device is supposed to be sdb1 (You should verify it using command lsblk , otherwise you will overwrite your disk and OS), use name of disk very cautiously!!!.

The dd command takes some time ranging from a few seconds to several minutes in execution, depending on the size and type of file and read and write speed of USB stick.
