hostname命令在屏幕上打印一句话,即自定义的本机名称。
hello 命令可以带多个参数,如hello a b c d,回车后会显示:
hello,I am Genie
your argv is:
a
b
c
d
(3)实现在串口和LCD的同步显示,即所有的命令操作过程都要显示在串口和LCD上。
二、 提高要求(选做)
自己设计几条新的命令,比如输入time即可显示时间,输入data即可显示日期或者可以通过命令设置时间和日期等。
-Genie- shell for TRACK 1, basic requirements (regimen) (1) design and implement CENTER shell model (2) to achieve a simple Shel l command hostname command on the screen print a word that is, since the definition of the machine name. Hello orders can take a number of parameters, such as hello a b c d, Enter will show : hello, I am your argv Genie is : a b c d (3) Achieve the serial synchronous and LCD display, that is, all the orders must show that the process of the serial and LCD.

首先需要一个递减的步长,这里我们使用的是9、5、3、1(最后的步长必须是1)。 工作原理是首先对相隔9-1个元素的所有内容排序,然后再使用同样的方法对相隔5-1个元素的排序,以次类推。
-First step reduced the need for a long, here is our use of 9,5,3,1 (the final step must be to 1). The first is that on the job between 9-1 months to sort all the content elements, and then use the same method of elements separated by the order of 5-1, an inferior race, and so on.
