This will preserve any blocks in the 2622 2645 output file not explicitly written by dd. The notrunc value is not 2623 2646 supported for tapes. 2647 2624 2648 *osync* 2649 2625 2650 Pad the final output block to the full output block size. If the 2626 2651 input file is not a multiple of the output block size after … … 2629 2654 regularly sized blocks to be written. This option is incompatible 2630 2655 with use of the bs=n block size specification. 2656 2631 2657 *sparse* 2658 2632 2659 If one or more non-final output blocks would consist solely of NUL 2633 2660 bytes, try to seek the output file by the required space instead of 2634 2661 filling them with NULs.

Spaces are used for 2641 2672 pad bytes if a block oriented conversion value is specified, otherwise 2642 2673 NUL bytes are used. 2674 2643 2675 *ucase* 2676 2644 2677 Transform lowercase characters into uppercase characters. 2678 2645 2679 *unblock* 2680 2646 2681 Treats the input as a sequence of fixed length records independent of 2647 2682 input and output block boundaries.
