Just enjoy, :)
guest@syclover:~$ cat WELCOME
Welcome to the World of Command.
Use "ls", "cat", "cd", "make", and "apt-get" to discover the world.
//应该是比较简单的。。。先来看一看目录形式吧
guest@syclover:~$ pwd
You are in a maze of twisty passages, all alike.
guest@syclover:~$ uname
Illudium Q-36 Explosive Space Modulator
//这些都是没有的信息。。。。
guest@syclover:~$ ls -a

//肯定在这个目录里了。。先进去看看
guest@syclover:~$ cd /tmp

//行了。。所有东西都出来了、、、
guest@syclover:~$ cat /tmp/Makefile

make: The program 'g++' is currently not installed. You can install it by typing:
make: sudo apt-get install g++

//没有编译器。。。果然要用 apt-get
guest@syclover:~$ sudo apt-get install g++

Use "wget", "irc", "apt-get", "poweroff", "reboot", "exit", "sleep", "man",
"vim", "emacs", "su", "uname", and Konami Code to have more fun.
Very special thanks to xkcd.com, you guys are awesome.
//就这么轻而易举的拿到了hash，
you guys are awesome...这很了不起吗？这道题目的难点不是在这里，并且根本没有涉及LINUX操作系统的更高级的操作。难点在这个HASH。。这个HASH看着不是一般的别扭。根本不像shadow的加密方法算出来的密文。。所以要得到Key值还需要后续解密步骤了。。
