按照使用以下 ROM 的教程进行操作时日实用程序,我收到控制台警告,称“1M”不是受支持的块大小。OSX 需要“1m”的块大小。Linux 和 OSX 具有不同块大小参数的根本原因是什么?
来自手册页日公用事业:
bs=n Set both input and output block size to n bytes, superseding the ibs and obs operands. If no
conversion values other than noerror, notrunc or sync are specified, then each input block is
copied to the output as a single block without any aggregation of short blocks.
