这家伙很懒，什么也没写！

修改成如下测试：

```
void sn(int argc, char* argv[])
{
int i; 
  rt_kprintf("These are the %d   command- line   arguments passed   to main:

", argc); 
  for(i=0; i<=argc; i++) 
      rt_kprintf("argv[%d]:%s
", i, argv[i]);

}
```

测试效果如下

```
sn a b c
Unknown symbol
finsh>>sn 2 a
Unknown symbol
finsh>>sn(2,a)
Expect a operater
finsh>>sn(3,a,1)
Expect a operater
finsh>>sn(3,2,1)
These are the 3   command- line   arguments passed   to main:
