Hi Michael & Oliver. Just to check what is going wrong here could you try to execute the following two commands: printf \\xa8\\x51\\x37\\x00 > x ; hexdump x /usr/bin/printf \\xa8\\x51\\x37\\x00 > x ; hexdump x echo -ne \\xa8\\x51\\x37\\x00 > x ; hexdump x Please try as above and also with full path to printf (/usr/bin/printf) On my system it looks like this: $ printf \\xa8\\x51\\x37\\x00 > x ; hexdump x 0000000 51a8 0037 0000004 $ /usr/bin/printf \\xa8\\x51\\x37\\x00 > x ; hexdump x 0000000 51a8 0037 0000004 $ echo -ne \\xa8\\x51\\x37\\x00 > x ; hexdump x 0000000 51a8 0037 0000004 Sam -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
