Test Your BASH Skills By Playing Command Line Games
======
![](https://www.ostechnix.com/wp-content/uploads/2018/03/Test-your-bash-skills-1-720x340.png)
We tend to learn and remember Linux commands more effectively if we use them regularly in a live scenario. You may forget the Linux commands over a period of time, unless you use them often. Whether you’re newbie, intermediate user, there are always some exciting methods to test your BASH skills. In this tutorial, I am going to explain how to test your BASH skills by playing command line games. Well, technically these are not actual games like Super TuxKart, NFS, or Counterstrike etc. These are just gamified versions of Linux command training lessons. You will be given a task to complete by follow certain instructions in the game itself.
Now, we will see few games that will help you to learn and practice Linux commands in real-time. These are not a time-passing or mind-boggling games. These games will help you to get a hands-on experience of terminal commands. Read on.
### Test BASH Skills with “Wargames”
It is an online game, so you must have an active Internet connection. These games helps you to learn and practice Linux commands in the form of fun-filled games. Wargames are collection of shell games and each game has many levels. You can access the next levels only by solving previous levels. Not to be worried! Each game provides clear and concise instructions about how to access the next levels.
To play the Wargames, go the following link:
![][2]
As you can see, there many shell games listed on the left side. Each shell game has its own SSH port. So, you will have to connect to the game via SSH from your local system. You can find the information about how to connect to each game using SSH in the top left corner of the Wargames website.
For instance, let us play the **Bandit** game. To do so, click on the Bandit link on the Wargames homepage. On the top left corner, you will see SSH information of the Bandit game.
![][3]
As you see in the above screenshot, there are many levels. To go to each level, click on the respective link on the left column. Also, there are instructions for the beginners on the right side. Read them if you have any questions about how to play this game.
Now, let us go to the level 0 by clicking on it. In the next screen, you will SSH information of this level.
![][4]
As you can see on the above screenshot, you need to connect is **bandit.labs.overthewire.org** , on port 2220 via SSH. The username is **bandit0** and the password is **bandit0**.
Let us connect to Bandit game level 0.
Enter the password i.e **bandit0**
Sample output will be:
![][5]
Once logged in, type **ls** command to see what’s in their or go to the **Level 1 page** to find out how to beat Level 1 and so on. The list of suggested command have been provided in every level. So, you can pick and use any suitable command to solve the each level.
I must admit that Wargames are addictive and really fun to solve each level. However some levels are really challenging, so you may need to google to know how to solve it. Give it a try, you will really like it.
### Test BASH Skills with “Terminus” game
This is a yet another browser-based online CLI game which can be used to improve or test your Linux command skills. To play this game, open up your web browser and navigate to the following URL.
Once you entered in the game, you see the instructions to learn how to play it. Unlike Wargames, you don’t need to connect to their game server to play the games. Terminus has a built-in CLI where you can find the instructions about how to play it.
You can look at your surroundings with the command **“ls”** , move to a new location with the command **“cd LOCATION”** , go back with the command **“cd ..”** , interact with things in the world with the command **“less ITEM”** and so on. To know your current location, just type **“pwd”**.
![][6]
### Test BASH Skills with “clmystery” game
Unlike the above games, you can play this game locally. You don’t need to be connected with any remote system. This is completely offline game.
Trust me, this is an interesting game folks. You are going to play a detective role to solve a mystery case by following the given instructions.
First, clone the repository:
```
$ git clone https://github.com/veltman/clmystery.git
```
Or, download it as a zip file from [**here**][7]. Extract it and go to the location where you have the files. Finally, solve the mystery case by reading the “instructions” file.
```
[sk@sk]: clmystery-master>$ ls
cheatsheet.md cheatsheet.pdf encoded hint1 hint2 hint3 hint4 hint5 hint6 hint7 hint8 instructions LICENSE.md mystery README.md solution
```
Here is the instructions to play this game:
There’s been a murder in Terminal City, and TCPD needs your help. You need to help them to figure out who did the crime.
To find out who did it, you need to go to the **‘mystery’** subdirectory and start working from there. You might need to look into all clues at the crime scene (the **‘crimescene’** file). The officers on the scene are pretty meticulous, so they’ve written down EVERYTHING in their officer reports. Fortunately the sergeant went through and marked the real clues with the word “CLUE” in all caps.
If you get stuck at anywhere, open one of the hint files such as hint1, hint2 etc. You can open the hint files using cat command like below.
```
$ cat hint1
$ cat hint2
```
To check your answer or find out the solution, open the file ‘solution’ in the clmystery directory.
```
$ cat solution
```
To get started on how to use the command line, refer **cheatsheet.md** or **cheatsheet.pdf** (from the command line, you can type ‘nano cheatsheet.md’). Don’t use a text editor to view any files except these instructions, the cheatsheet, and hints.
For more details, refer the [**clmystery GitHub**][8] page.
**Recommended read:**
And, that’s all I can remember now. I will keep adding more games if I came across anything in future. Bookmark this link and do visit from time to time. If you know any other similar games, please let me know in the comment section below. I will test and update this guide.
More good stuffs to come. Stay tuned!
Cheers!

通过玩命令行游戏来测试你的 BASH 技能
=====
![](https://www.ostechnix.com/wp-content/uploads/2018/03/Test-your-bash-skills-1-720x340.png)
如果我们经常在实际场景中使用 Linux 命令，我们倾向于更有效的学习和记忆它们。除非你经常使用 Linux 命令，否则你可能会在一段时间内忘记它们。无论你是新手还是中级用户，总会有一些令人兴奋的方法来测试你的 BASH 技能。在本教程中，我将解释如何通过玩命令行游戏来测试你的 BASH 技能。其实从技术上讲，这些并不是真正的游戏，如 Super TuxKart，NFS 或 Counterstrike 等等。这些只是 Linux 命令培训课程的游戏化版本。你将根据游戏本身的某些指示来完成一个任务。
现在，我们将看到几款能帮助你实时学习和练习 Linux 命令的游戏。这些游戏不是消磨时间或者令人惊诧的，这些游戏将帮助你获得终端命令的真实体验。请继续阅读：
### 使用 “Wargames” 来测试 BASH 技能
这是一个在线游戏，所以你必须和互联网保持连接。这些游戏可以帮助你以充满乐趣的游戏形式学习和练习 Linux 命令。Wargames 是 shell 游戏的集合，每款游戏有很多关卡。只有通过解决先前的关卡才能访问下一个关卡。不要担心！每个游戏都提供了有关如何进入下一关的清晰简洁说明。
要玩 Wargames，请点击以下链接：
![][2]
如你所见，左边列出了许多 shell 游戏。每个 shell 游戏都有自己的 SSH 端口。所以，你必须通过本地系统配置 SSH 连接到游戏，你可以在 Wargames 网站的左上角找到关于如何使用 SSH 连接到每个游戏的信息。
例如，让我们来玩 **Bandit** 游戏吧。为此，单击 Wargames 主页上的 Bandit 链接。在左上角，你会看到 Bandit 游戏的 SSH 信息。
![][3]
正如你在上面的屏幕截图中看到的，有很多关卡。要进入每个关卡，请单机左侧列中的相应链接。此外，右侧还有适合初学者的说明。如果你对如何玩此游戏有任何疑问，请阅读它们。
现在，让我们点击它进入关卡 0。在下一个屏幕中，你将获得该关卡的 SSH 信息。
![][4]
正如你在上面的屏幕截图中看到的，你需要配置 SSH 端口 2220 连接 **bandit.labs.overthewire.org**，用户名是 **bandit0**，密码是 **bandit0**。
让我们连接到 Bandit 游戏关卡 0。
输入密码 **bandit0**
示例输出将是：
![][5]
登录后，输入 **ls** 命令查看内容或者进入 **关卡 1 页面**，了解如何通过关卡 1 等等。建议的命令列表已在每个关卡提供。所以，你可以选择和使用任何合适的命令来解决每个关卡。
我必须承认，Wargames 是令人上瘾的，并且解决每个关卡是非常有趣的。 尽管有些关卡确实很具挑战性，你可能需要谷歌才能知道如何解决问题。 试一试，你会很喜欢它。
### 使用 “Terminus” 来测试 BASH 技能
这是另一个基于浏览器的在线 CLI 游戏（译注：CLI 命令行界面），可用于改进或测试你的 Linux 命令技能。要玩这个游戏，请打开你的 web 浏览器并导航到以下 URL。
一旦你进入游戏，你会看到有关如何玩游戏的说明。与 Wargames 不同，你不需要连接到它们的游戏服务器来玩游戏。Terminus 有一个内置的 CLI，你可以在其中找到有关如何使用它的说明。
你可以使用命令 **“ls”** 查看周围的环境，使用命令 **“cd LOCATION”** 移动到新的位置，返回使用命令 **“cd ..”**，与这个世界进行交互使用命令 **“less ITEM”** 等等。要知道你当前的位置，只需输入 **“pwd”**。
![][6]
### 使用 “clmystery” 来测试 BASH 技能
与上述游戏不同，你可以在本地玩这款游戏。你不需要连接任何远程系统，这是完全离线的游戏。
相信我，这是一个有趣的游戏人。按照给定的说明，你将扮演一个侦探角色来解决一个神秘案件。
首先，克隆仓库：
```
$ git clone https://github.com/veltman/clmystery.git
```
或者，从 [这里][7] 将其作为 zip 文件下载。解压缩并切换到下载文件的地方。左后，通过阅读 “instructions” 文件来解决神秘案例。
```
[sk@sk]: clmystery-master>$ ls
cheatsheet.md cheatsheet.pdf encoded hint1 hint2 hint3 hint4 hint5 hint6 hint7 hint8 instructions LICENSE.md mystery README.md solution
```
这里是玩这个游戏的说明：
终端城发生了一起谋杀案，TCPD 需要你的帮助。你需要帮助它们弄清楚是谁犯罪了。
为了查明是谁干的，你需要到 **‘mystery’** 子目录并从那里开始工作。你可能需要查看犯罪现场的所有线索（ **‘crimescene’** 文件）。现场的警官相当谨慎，所以他们在警官报告中写下了一切。幸运的是，警官在所有的帽子里都用了 “CLUE” 一词，并把真正的线索标记了出来。
如果里遇到任何问题，请打开其中一个提示文件，例如 hint1，hint2 等。你可以使用下面的 cat 命令打开提示文件。
```
$ cat hint1
$ cat hint2
```
要检查你的答案或找出解决方案，请在 clmystery 目录中打开文件 “solution”。
```
$ cat solution
```
要开始如何使用命令行，请参阅 **cheatsheet.md** 或 **cheatsheet.pdf** （在命令行中，你可以输入 ‘nano cheatsheet.md’）。请勿使用文本编辑器查看除说明，备忘录和提示以外的任何文件。
有关更多详细信息，请参阅 [**clmystery GitHub**][8] 页面。

而这就是我现在所能记得的。如果将来遇到任何问题，我会继续添加更多游戏。将此链接加入书签并不时访问。如果你知道其他类似的游戏，请在下面的评论部分告诉我，我将测试和更新本指南。
还有更多好东西，敬请关注！
干杯！
