You are going to clone the partition $/$dev$/$sdb$1$ into $/$dev$/$sdb$2,$ that is$,$ an exact copy. First, free the destination by executing umount $/$dev$/$sdb$2.$ Then, execute the cloning command, dd if$=/$dev$/$sdb$1$ of$=/$dev$/$sdb$2$ bs$=1$M$.$ Finally, create the mount point $/$mnt$/$copy and mount it again with mount $/$dev$/$sdb$2/$mnt$/$copy$.$ Both should be identical as per the output of ls $/$mnt$/$data $/$mnt$/$copy$.$ Show all operations.
