This should do it (on gnu dd):
dd if=somefile bs=4096 skip=1337 count=31337000 iflag=skip_bytes,count_bytes
In case you are using
seek=
as well, you may also consider
oflag=seek_bytes
.
From info dd:
- count_bytes: Interpret the
count=
operand as a byte count, rather than a block count, which allows specifying a length that is not a multiple of the I/O block size. This flag can be used only with iflag
.
- skip_bytes: Interpret the
skip=
operand as a byte count, rather than a block count, which allows specifying an offset that is not a multiple of the I/O block size. This flag can be used only with iflag
.
- seek_bytes: Interpret the
seek=
operand as a byte count, rather than a block count, which allows specifying an offset that is not a multiple of the I/O block size. This flag can be used only with oflag
.
