How to bring good fortune to your Linux terminal
|
|
||||||
======
|
|
||||||
Bring quotes and quips to the command line with the fortune utility.
|
|
||||||
|
|
||||||
|
|
||||||
It's December, and if you haven't found a [tech advent calendar][1] that sparks your fancy yet, well, maybe this one will do the trick. Every day, from now to the 24th, we're bringing you a different Linux command-line toy. What's a command-line toy, you ask? It could be a game or any simple diversion to bring a little happiness to your terminal.
|
|
||||||
|
|
||||||
You may have seen some of these before. We hope you'll find something new, too. Either way, we hope you have fun following along.
|
|
||||||
|
|
||||||
Today's toy, **fortune** , is an old one. Versions of it date back to the 1980s when it was included with Unix. The version I installed in Fedora was available under a BSD license, and I grabbed it with the following.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ sudo dnf install fortune-mod -y
|
|
||||||
```
|
|
||||||
|
|
||||||
Your distribution may be different. On some, you may need to install the fortunes separately from **fortune** itself (try searching your package manager for "fortunes*"). You can also check out the source code on [GitHub][2]. Then, just run **fortune** to get, well, a fortune.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ fortune
|
|
||||||
"Time is an illusion. Lunchtime doubly so."
|
|
||||||
-- Ford Prefect, _Hitchhiker's Guide to the Galaxy_
|
|
||||||
```
|
|
||||||
|
|
||||||
So why do you need fortunes at the terminal? For fun, of course. Perhaps you'd like to add them to the message of the day on your system?
|
|
||||||
|
|
||||||
Personally, I like using the **fortune** command as a built-in piece of dummy data when I'm using the terminal to parse text, particularly with [regular expressions][3], and want something simple to try it out on.
|
|
||||||
|
|
||||||
For example, let's say I was testing our a transformation with the **tr** command to replace letter the letter e with a numeral 3.
|
|
||||||
|
|
||||||
```
|
|
||||||
$ fortune | tr 'eE' '3'
|
|
||||||
Unix 3xpr3ss:
|
|
||||||
All pass3ng3r bring a pi3c3 of th3 a3roplan3 and a box of tools with th3m to
|
|
||||||
th3 airport. Th3y gath3r on th3 tarmac, arguing constantly about what kind
|
|
||||||
of plan3 th3y want to build and how to put it tog3th3r. 3v3ntually, th3
|
|
||||||
pass3ng3rs split into groups and build s3v3ral diff3r3nt aircraft, but giv3
|
|
||||||
th3m all th3 sam3 nam3. Som3 pass3ng3rs actually r3ach th3ir d3stinations.
|
|
||||||
All pass3ng3rs b3li3v3 th3y got th3r3.
|
|
||||||
```
|
|
||||||
|
|
||||||
So what fortunes come with your distribution? Take a look in your **/usr/share/games/fortune** directory to find them all. Here are a few of my favorites.
|
|
||||||
|
|
||||||
```
|
|
||||||
Never laugh at live dragons.
|
|
||||||
-- Bilbo Baggins [J.R.R. Tolkien, "The Hobbit"]
|
|
||||||
|
|
||||||
I dunno, I dream in Perl sometimes...
|
|
||||||
-- Larry Wall in <8538@jpl-devvax.JPL.NASA.GOV>
|
|
||||||
|
|
||||||
I have an existential map. It has "You are here" written all over it.
|
|
||||||
-- Steven Wright
|
|
||||||
```
|
|
||||||
|
|
||||||
Looking for more on **fortune**? You can, of course, always check out the man page to learn more about the options, or read a little bit more about the history of the command on [Wikipedia][4].
|
|
||||||
|
|
||||||
Do you have a favorite command-line toy that you think I ought to profile? The calendar for this series is mostly filled out but I've got a few spots left. Let me know in the comments below, and I'll check it out. If there's space, I'll try to include it. If not, but I get some good submissions, I'll do a round-up of honorable mentions at the end.
|
|
||||||
|
|
||||||
Check out yesterday's toy, [Drive a locomotive through your Linux terminal][5], and check back tomorrow for another!

如何为你的 Linux 终端带来好运
|
||||||
|
======
|
||||||
|
使用 fortune 实用程序将引号和俏皮话带到命令行。
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
这是 12 月，如果你还没有找到一款能激发你灵感的[科技降临节日历][1]，那么，也许这个系列可以。从现在到 24 日，每天我们都会为你带来一个不同的 Linux 命令行玩具。你可能会问，什么是命令行玩具？它可能是一个游戏或任何简单的娱乐，为你的终端带来一点点快乐。
|
||||||
|
|
||||||
|
你可能之前已经看过其中的一些，我们希望你也能发现一些新的东西。不管怎样，我们都希望你在关注时保有乐趣。
|
||||||
|
|
||||||
|
今天的玩具是 **fortune**，它很古老。它的版本可以追溯到 1980 年，当时它包含在 Unix 中。我在 Fedora 中安装的版本是在 BSD 许可下提供的，我可以使用以下命令获取它。
|
||||||
|
```
|
||||||
|
$ sudo dnf install fortune-mod -y
|
||||||
|
```
|
||||||
|
|
||||||
|
你的发行版可能会有所不同。在某些情况下，你可能需要将 fortunes 独立于 **fortune** 本身安装（尝试在你的包管理器中搜索 "fortunes"）。你还可以在 [GitHub][2] 上查看它的源代码，然后，只需运行 **fortune** 即可获得好运。
|
||||||
|
|
||||||
|
```
|
||||||
|
$ fortune
|
||||||
|
"Time is an illusion. Lunchtime doubly so."
|
||||||
|
-- Ford Prefect, _Hitchhiker's Guide to the Galaxy_
|
||||||
|
```
|
||||||
|
|
||||||
|
那么，你为什么会在终端上需要 fortune 呢？当然是为了好玩啦。也许你想将它们添加到系统上的每天消息中？
|
||||||
|
|
||||||
|
就我个人而言，当我使用终端来解析文本时，我喜欢使用 **fortune** 命令作为一段内置的虚拟数据，特别是使用[正则表达式][3]时，我想要一些简单的东西来尝试一下。
|
||||||
|
|
||||||
|
例如，假设我使用 **tr** 命令来测试转换，用数字 3 替换字母 e。
|
||||||
|
|
||||||
|
```
|
||||||
|
$ fortune | tr 'eE' '3'
|
||||||
|
Unix 3xpr3ss:
|
||||||
|
All pass3ng3r bring a pi3c3 of th3 a3roplan3 and a box of tools with th3m to
|
||||||
|
th3 airport. Th3y gath3r on th3 tarmac, arguing constantly about what kind
|
||||||
|
of plan3 th3y want to build and how to put it tog3th3r. 3v3ntually, th3
|
||||||
|
pass3ng3rs split into groups and build s3v3ral diff3r3nt aircraft, but giv3
|
||||||
|
th3m all th3 sam3 nam3. Som3 pass3ng3rs actually r3ach th3ir d3stinations.
|
||||||
|
All pass3ng3rs b3li3v3 th3y got th3r3.
|
||||||
|
```
|
||||||
|
|
||||||
|
那么 fortunes 到底为你的发行版带来了什么呢？看看你的 **/usr/share/games/fortune** 目录，找到它们。以下我最喜欢的几个。
|
||||||
|
```
|
||||||
|
Never laugh at live dragons.

||||||
|

|
||||||

|
||||||
|

|
||||||
|
-- Larry Wall in <8538@jpl-devvax.JPL.NASA.GOV>
|
||||||
|
|
||||||
|

|
||||||
|

|
||||||
|
```
|
||||||
|
|
||||||
|
想要了解更多关于 **fortune**？当然，你可以经常查看 man 页来了解更多选项，或者在[维基百科][4]上阅读更多关于此命令的历史信息。
|
||||||
|
|
||||||
|
你有特别喜欢的命令行小玩具需要我介绍的吗？这个系列要介绍的小玩具大部分已经有了落实，但还预留了几个空位置。请在评论区留言，我会查看的。如果还有空位置，我会考虑介绍它的。如果没有，但如果我得到了一些很好的意见，我会在最后做一些有价值的提及。
|
||||||
|
|
||||||
|
看看昨天的玩具：[驾驶火车头通过你的 Linux 终端][5]。记得明天再来！
