Hello Coreutils, The subj is a requirement if I'm copying between overlapping regions, and the destination is further in the media than the source.
The specific task I'm having is to move a partition a number of sectors forward. To be completely clear, the algorithm is: copy a block, then seek to the previous block (i.e. 2*bs bytes back). I don't currently see a use case for setting this for input/output independently. An idea for the option name is `d'. There is a workaround for my particular case - `dd if=<block_device> bs=<2*shift_bytes> | dd of=<block_device> seek=<shift_blocks>' but it requires a few times 2*shift_bytes of memory. -- Best regards, Ivan mailto:[email protected]
