dd - unrecongnized operand of=/dev/sdc when trying to create a bootable USB

  • 772

I am trying to create a bootable USB. Currently on lsblk I have sdc -> sdc1, formatted to fat32.

I am trying now to save my iso with the following command:

sudo dd if=/dev/puppylinux.iso \ of=/dev/sdc bs=4M && sync status=progress

The error I am getting is:

dd: unrecognized operand ‘ of=/dev/sdc’

From all the searching I did, I can see that the of=...should be as I wrote it to be. What am I doing wrong?

    The dd command that you tried has an unnecessary / character after if=/dev/puppylinux.iso which should be removed. sync is a separate command, so it goes after the && so that sync runs only if the first command ( dd ) ran.

    The correct command is:

    sudo dd if=/dev/puppylinux.iso of=/dev/sdc bs=4M status=progress && sync
