    # 爬過您的終端機<br><small>——Python 可不是終端機裡唯一的蛇,還有這個 1970 年代的經典遊戲!</small> :::info 原文:[Snake your way across your Linux terminal](https://opensource.com/article/18/12/linux-toy-snake) 原作者:[Jason Baker (Red Hat)](https://opensource.com/users/jason-baker) 台灣中文譯者:[Franklin Weng](https://about.me/fweng322) 編譯團隊註:這一系列文章是 opensource.com 搭配降臨節日曆(Advent calendar)所推出的一系列 Linux 命令列小工具介紹。所謂的「降臨節日曆」簡單地說,就是一個小日曆,每一天是一格,從 12 月 1 日開始,每天可以從格子中取出一個小禮物,直到聖誕節到來為止。因此在這一系列中,我們將會介紹 24 個有趣的 Linux 終端機、命令列上的小工具。 ::: ![](https://i.imgur.com/8abo1TF.png) 圖片由 *Jason Baker* 提供 歡迎回到 Linux 命令列小玩意介紹的行列。如果您是今天才看到這一系列文章,您可能會問什麼是命令列小工具?嗯,有點難解釋,我自己的定意是任何能在終端機內帶給您樂趣的任何小程式都算。 我們前幾天介紹了幾款好玩的經典遊戲,今天再來看另一個小遊戲:貪食蛇! 貪食蛇是個古老但非常棒的遊戲;它不斷被改寫成各種不同的版本。我還記得我玩過的第一個版本是在 1990 年代與 [QBasic](https://en.wikipedia.org/wiki/QBasic) 包在一起的,叫做 [Nibble](https://en.wikipedia.org/wiki/Nibbles_(video_game)),這個程式也讓我瞭解所謂的程式語言是怎麼一回事。因為我可以改改它的程式源碼,學習那些小小的關鍵字怎麼變成一個程式的。 今天介紹的[貪食蛇](https://github.com/DyegoCosta/snake-game)是用 Go 寫成的。雖然它很簡單,但跟原始版本一樣好玩。許多簡單而經典的遊戲都有許多許多版本,貪食蛇也是,甚至在傳統的 [bsdgames](https://github.com/vattam/BSDGames) 軟體包中都有(這表示您的 Linux 系統中預設的軟體庫中就有貪食蛇啦!) 不過我今天要介紹的版本,是包在 Docker 中,所以我可以輕鬆在我的終端機裡用一行指令就可以執行,不用管系統與軟體相依性的問題。另外,它用表情符號中的食物給貪食蛇吃。您的系統中若已經安裝好 docker,那麼以下指令就可以馬上玩: <code>$ docker run -ti dyego/snake-game</code> 這個貪食蛇的版本是以 MIT 授權釋出,您可以在 [GitHub](https://github.com/DyegoCosta/snake-game) 上看到它的程式源碼。 ![](https://i.imgur.com/cSqTv0c.gif) 您有最喜歡的命令列小工具,認為我們應該要介紹的嗎?可以在下方留言給我們。 這裡是昨天介紹的小工具:[二的乘方,Linux 的力量:在終端機裡玩 2048](https://hackmd.io/_qy1B0K6Q_qoDuCFLsaF0A)。敬請期待明天的介紹! ###### tags: `Linux` `Advent Calendar` `Console` `終端機` `命令列`
