specified, the input block is omitted from the output. On input files
which are not tapes or pipes, the file offset will be positioned past
the block in which the error occurred using lseek(2).
*notrunc*
Do not truncate the output file. This will preserve any blocks in the
output file not explicitly written by dd. The notrunc value is not
supported for tapes.
*osync*
Pad the final output block to the full output block size. If the
input file is not a multiple of the output block size after
conversion, this conversion forces the final output block to be the
same size as preceding blocks for use on devices that require
regularly sized blocks to be written. This option is incompatible
with use of the bs=n block size specification.
*sparse*
If one or more non-final output blocks would consist solely of NUL
bytes, try to seek the output file by the required space instead of
filling them with NULs. This results in a sparse file on some file
systems.
*swab*
Swap every pair of input bytes. If an input buffer has an odd number
of bytes, the last byte will be ignored during swapping.
*sync*
Pad every input block to the input buffer size. Spaces are used for
pad bytes if a block oriented conversion value is specified, otherwise
NUL bytes are used.
*ucase*
Transform lowercase characters into uppercase characters.
