Mark my words, friends, someday your eyes will be decrepit and you won't be able to read those tiny fonts you coded into everything, and then you'll be sorry, and I will laugh. - -Fortunately, Linux fans, you can change your console fonts. As always, the ever-changing Linux landscape makes this less than straightforward, and font management on Linux is non-existent, so we'll muddle along as best we can. In this article, I'll show what I've found to be the easiest approach. - -### What is the Linux Console? - -Let us first clarify what we're talking about. When I say Linux console, I mean TTY1-6, the virtual terminals that you access from your graphical desktop with Ctrl+Alt+F1 through F6. To get back to your graphical environment, press Alt+F7. (This is no longer universal, however, and your Linux distribution may have it mapped differently. You may have more or fewer TTYs, and your graphical session may not be at F7. For example, Fedora puts the default graphical session at F2, and an extra one at F1.) I think it is amazingly cool that we can have both X and console sessions running at the same time. - -The Linux console is part of the kernel, and does not run in an X session. This is the same console you use on headless servers that have no graphical environments. I call the terminals in a graphical session X terminals, and terminal emulators is my catch-all name for both console and X terminals. - -But that's not all. The Linux console has come a long way from the early ANSI days, and thanks to the Linux framebuffer, it has Unicode and limited graphics support. There are also a number of console multimedia applications that we will talk about in a future article. - -### Console Screenshots - -The easy way to get console screenshots is from inside a virtual machine. Then you can use your favorite graphical screen capture program from the host system. You may also make screen captures from your console with [fbcat][1] or [fbgrab][2]. `fbcat` creates a portable pixmap format (PPM) image; this is a highly portable uncompressed image format that should be readable on any operating system, and of course you can convert it to whatever format you want. `fbgrab` is a wrapper script to `fbcat` that creates a PNG file. There are multiple versions of `fbgrab` written by different people floating around. Both have limited options and make only a full-screen capture. - -`fbcat` needs root permissions, and must redirect to a file. Do not specify a file extension, but only the filename: -``` -$ sudo fbcat > Pictures/myfile - -``` - -After cropping in GIMP, I get Figure 1. - -It would be nice to have a little padding on the left margin, so if any of you excellent readers know how to do this, please tell us in the comments. - -`fbgrab` has a few more options that you can read about in `man fbgrab`, such as capturing a different console, and time delay. This example makes a screen grab just like `fbcat`, except you don't have to explicitly redirect: -``` -$ sudo fbgrab Pictures/myOtherfile - -``` - -### Finding Fonts - -As far as I know, there is no way to list your installed kernel fonts other than looking in the directories they are stored in: `/usr/share/consolefonts/` (Debian/etc.), `/lib/kbd/consolefonts/` (Fedora), `/usr/share/kbd/consolefonts` (openSUSE)...you get the idea. - -### Changing Fonts - -Readable fonts are not a new concept. Embrace the old! Readability matters. And so does configurability, which sometimes gets lost in the rush to the new-shiny. - -On Debian/Ubuntu/etc. systems you can run `sudo dpkg-reconfigure console-setup` to set your console font, then run the `setupcon` command in your console to activate the changes. `setupcon` is part of the `console-setup` package. If your Linux distribution doesn't include it, there might be a package for you at [openSUSE][3]. - -You can also edit `/etc/default/console-setup` directly. This example sets the Terminus Bold font at 32 points, which is my favorite, and restricts the width to 80 columns. -``` -ACTIVE_CONSOLES="/dev/tty[1-6]" -CHARMAP="UTF-8" -CODESET="guess" -FONTFACE="TerminusBold" -FONTSIZE="16x32" -SCREEN_WIDTH="80" - -``` - -The FONTFACE and FONTSIZE values come from the font's filename, `TerminusBold32x16.psf.gz`. Yes, you have to know to reverse the order for FONTSIZE. Computers are so much fun. Run `setupcon` to apply the new configuration. You can see the whole character set for your active font with `showconsolefont`. Refer to `man console-setup` for complete options. - -### Systemd - -Systemd is different from `console-setup`, and you don't need to install anything, except maybe some extra font packages. All you do is edit `/etc/vconsole.conf` and then reboot. On my Fedora and openSUSE systems I had to install some extra Terminus packages to get the larger sizes as the installed fonts only went up to 16 points, and I wanted 32. This is the contents of `/etc/vconsole.conf` on both systems: -``` -KEYMAP="us" -FONT="ter-v32b" - -``` - -Come back next week to learn some more cool console hacks, and some multimedia console applications. - -Learn more about Linux through the free ["Introduction to Linux" ][4]course from The Linux Foundation and edX. - --------------------------------------------------------------------------------- - -via: https://www.linux.com/learn/intro-to-linux/2018/1/how-change-your-linux-console-fonts - -作者：[Carla Schroder][a] -译者：[lujun9972](https://github.com/lujun9972) -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://www.linux.com/users/cschroder -[1]:http://jwilk.net/software/fbcat -[2]:https://github.com/jwilk/fbcat/blob/master/fbgrab -[3]:https://software.opensuse.org/package/console-setup -[4]:https://training.linuxfoundation.org/linux-courses/system-administration-training/introduction-to-linux diff --git a/translated/tech/20180104 How to Change Your Linux Console Fonts.md b/translated/tech/20180104 How to Change Your Linux Console Fonts.md new file mode 100644 index 0000000000..245f15924e --- /dev/null +++ b/translated/tech/20180104 How to Change Your Linux Console Fonts.md @@ -0,0 +1,88 @@ +如何更改 Linux 控制台上的字体 +====== +![](https：//www.linux.com/sites/lcom/files/styles/rendered_file/public/font-size_0.png？itok=d97vmyYa) + +我尝试尽可能的保持心灵祥和，然而总有一些事情让我意难平，比如控制台字体太小了。记住我的话，朋友，有一天你的眼睛会退化，无法再看清你编码时用的那些细小字体，到那时你就后悔莫及了。 + +幸好，Linux 死忠们，你可以更改控制台的字体。按照 Linux 一贯的尿性，不断变化的 Linux 环境使得这个问题变得不太简单明了，而 Linux 上也没有字体管理这么个东西，这使得我们很容易就被搞晕了。本文，我将会向你展示，我找到的更改字体的最简方法。 + +### Linux 控制台是个什么鬼？ + +首先让我们来澄清一下我们说的到底是个什么东西。当我提到 Linux 控制台，我指的是 TTY1-6，即你从图形环境用 `Ctrl-Alt-F1` 到 `F6` 切换到的虚拟终端。按下 `Ctrl+Alt+F7` 会切回图形环境。(不过这些热键已经不再通用，你的 Linux 发行版可能有不同的键映射。你的 TTY 的数量也可能不同，你图形环境会话也可能不在 `F7`。比如，Fedora 的默认图形会话是 `F2`，它只有一个额外的终端在 `F1`。) 我觉得能同时拥有 X 会话和终端绘画实在是太酷了。 + +Linux 控制台是内核的一部分，而且并不运行在 X 会话中。它和你在没有图形环境的无头服务器中用的控制台是一样的。我称呼在图形会话中的 X 终端为终端，而将控制台和 X 终端统称为终端模拟器。 + +但这还没完。Linux 终端从早期的 ANSI 时代开始已经经历了长久的发展，多亏了 Linux framebuffer，它现在支持 Unicode 并且对图形也有了有限的一些支持。而且出现了很多在控制台下运行的多媒体应用，这些我们在以后的文章中会提到。 + +### 控制台截屏 + +获取控制台截屏的最简单方法是让控制台跑在虚拟机内部。然后你可以在宿主系统上使用中意的截屏软件来抓取。不过借助 [fbcat][1] 和 [fbgrab][2] 你也可以直接在控制台上截屏。`fbcat` 会创建一个可移植的像素映射格式 (PPM) 图像; 这是一个高度可移植的未压缩图像格式，可以在所有的操作系统上读取，当然你也可以把它转换成任何喜欢的其他格式。`fbgrab` 则是 `fbcat` 的一个封装脚本，用来生成一个 PNG 文件。不同的人写过多个版本的 `fbgrab`。每个版本的选项都有限而且只能创建截取全屏。 + +`fbcat` 的执行需要 root 权限，而且它的输出需要重定向到文件中。你无需指定文件扩展名，只需要输入文件名就行了： +``` +$ sudo fbcat > Pictures/myfile + +``` + +在 GIMP 中裁剪后，就得到了图 1。 + +![](https：//www.linux.com/sites/lcom/files/styles/rendered_file/public/fig-1_10.png？itok=bHOxrZk9) +Figure 1：View after cropping。 + +如果能在左边空白处有一点填充就好了，如果有读者知道如何实现请在留言框中告诉我。 + +`fbgrab` 还有一些选项，你可以通过 `man fbgrab` 来查看，这些选项包括对另一个控制台进行截屏，以及延时截屏。在下面的例子中可以看到，`fbgrab` 截屏跟 `fbcat` 截屏类似，只是你无需明确进行输出重定性了： +``` +$ sudo fbgrab Pictures/myOtherfile + +``` + +### 查找字体 + +就我所知，除了查看字体存储目录 `/usr/share/consolefonts/`(Debian/etc。)，`/lib/kbd/consolefonts/` (Fedora)，`/usr/share/kbd/consolefonts` (openSUSE)，外没有其他方法可以列出已安装的字体了。 + +### 更改字体 + +可读字体不是什么新概念。我们应该尊重以前的经验！可读性是很重要的。可配置性也很重要，然而现如今却不怎么看重了。 + +在 Debian/Ubuntu/ 等系统上，可以运行 `sudo dpkg-reconfigure console-setup` 来设置控制台字体，然后在控制台运行 `setupcon` 命令来让变更生效。`setupcon` 属于 `console-setup` 软件包中的一部分。若你的 Linux 发行版中不包含该工具，可以在 [openSUSE][3] 中下载到它。 + +你也可以直接编辑 `/etc/default/console-setup` 文件。下面这个例子中设置字体为 32 点大小的 Terminus Bold 字体，这是我的最爱，并且严格限制控制台宽度为 80 列。 +``` +ACTIVE_CONSOLES="/dev/tty[1-6]" +CHARMAP="UTF-8" +CODESET="guess" +FONTFACE="TerminusBold" +FONTSIZE="16x32" +SCREEN_WIDTH="80" + +``` + +这里的 FONTFACE 和 FONTSIZE 的值来自于字体的文件名，`TerminusBold32x16.psf.gz`。是的，你需要反转 FONTSIZE 中值的顺序。计算机就是这么搞笑。然后再运行 `setupcon` 来让新配置生效。可以使用 `showconsolefont` 来查看当前所用字体的所有字符集。要查看完整的选项说明请参考 `man console-setup`。 + +### Systemd + +Systemd 与 `console-setup` 不太一样，除了字体之外，你无需安装任何东西。你只需要编辑 `/etc/vconsole.conf` 然后重启就行了。我在 Fedora 和 openSUSE 系统中安装了一些额外的大型号的 Terminus 字体包，因为默认安装的字体最大只有 16 点而我想要的是 32 点。然后将 `/etc/vconsole.conf` 的内容修改为： +``` +KEYMAP="us" +FONT="ter-v32b" + +``` + +下周我们还将学习一些更加酷的控制台小技巧，以及一些在控制台上运行的多媒体应用。 + + +-------------------------------------------------------------------------------- + +via: https://www.linux.com/learn/intro-to-linux/2018/1/how-change-your-linux-console-fonts + +作者：[Carla Schroder][a] +译者：[lujun9972](https://github.com/lujun9972) +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://www.linux.com/users/cschroder +[1]:http://jwilk.net/software/fbcat +[2]:https://github.com/jwilk/fbcat/blob/master/fbgrab +[3]:https://software.opensuse.org/package/console-setup
