Lab1: Xv6 and Unix utilities

Lab1 contains serveral small tasks, most of them is quiet easy. We need implement some utilities using system calls provide by the Xv6.

sleep

Xv6 already has a sleep system call, meaning that we just need to parse command line arguments and call the function.

    int time;
    time = atoi(argv[1]);
    sleep(time);

pingpong

Pinpong requires us using syscall fork() and Pipe() to send the message between two process.
