specify a different block size for input/read (IBS) and Output/write (OBS) options that override the IBS and OBS options, The default block size for input and output is 512 bytes (the traditional disk block and the size of the POSIX-defined block) for the Count option to replicate. The Read (skip) option and the Write (seek) option are all in blocks. The conversion operation is also thin "convert block Siz
