I used this trick the other day -- compute byte range partitions on a large file and use fseek when processing each. Is there a standard unix program that can output an arbitrary byte range from a seekable input? At first blush dd(1) looked like the ticket, but block-oriented operation means extra invocations to deal with a byte range that's not necessarily block-aligned.
