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! + +-------------------------------------------------------------------------------- + +via: https://opensource.com/article/18/12/linux-toy-fortune + +作者：[Jason Baker][a] +选题：[lujun9972][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://opensource.com/users/jason-baker +[b]: https://github.com/lujun9972 +[1]: https://opensource.com/article/16/11/7-tech-advent-calendars-holiday-season +[2]: https://github.com/shlomif/fortune-mod +[3]: https://opensource.com/article/18/5/getting-started-regular-expressions +[4]: https://en.wikipedia.org/wiki/Fortune_%28Unix%29 +[5]: https://opensource.com/article/18/12/linux-toy-sl
