Change your Linux terminal color theme
|
|
||||||
======
|
|
||||||
Your terminal has plenty of options that allow you to theme what you
|
|
||||||
see.
|
|
||||||

|
||||||
|
|
||||||
If you spend most of your day staring into a terminal, it's only natural that you want it to look pleasing. Beauty is in the eye of the beholder, and terminals have come a long way since the days of CRT serial consoles. So, the chances are good that your software terminal window has plenty of options to theme what you see—however you define beauty.
|
|
||||||
|
|
||||||
### Settings
|
|
||||||
|
|
||||||
Most popular software terminal applications, including GNOME, KDE, and Xfce, ship with the option to change their color theme. Adjusting your theme is as easy as adjusting application preferences. Fedora, RHEL, and Ubuntu ship with GNOME by default, so this article uses that terminal as its example, but the process is similar for Konsole, Xfce terminal, and many others.
|
|
||||||
|
|
||||||
First, navigate to the application's Preferences or Settings panel. In GNOME terminal, you reach it through the Application menu along the top of the screen or in the right corner of the window.
|
|
||||||
|
|
||||||
In Preferences, click the plus symbol (+) next to Profiles to create a new theme profile. In your new profile, click the Colors tab.
|
|
||||||
|
|
||||||
![GNOME Terminal preferences][2]
|
|
||||||
|
|
||||||
In the Colors tab, deselect the Use Colors From System Theme option so that the rest of the window will become active. As a starting point, you can select a built-in color scheme. These include light themes, with bright backgrounds and dark foreground text, as well as dark themes, with dark backgrounds and light foreground text.
|
|
||||||
|
|
||||||
The Default Color swatches define both the foreground and background colors when no other setting (such as settings from the dircolors command) overrides them. The Palette sets the colors defined by the dircolors command. These colors are used by your terminal, in the form of the LS_COLORS environment variable, to add color to the output of the [ls][3] command. If none of them appeal to you, change them on this screen.
|
|
||||||
|
|
||||||
When you're happy with your theme, close the Preferences window.
|
|
||||||
|
|
||||||
To change your terminal to your new profile, click on the Application menu, and select Profile. Choose your new profile and enjoy your custom theme.
|
|
||||||

|
||||||

|
||||||
### Command options
|
|
||||||
|
|
||||||
If your terminal doesn't have a fancy settings window, it may still provide options for colors in your launch command. The xterm and rxvt terminals (the old one and the Unicode-enabled variant, sometimes called urxvt or rxvt-unicode) provide such options, so you can still theme your terminal emulator—even without desktop environments and big GUI frameworks.
|
|
||||||
|
|
||||||
The two obvious options are the foreground and background colors, defined by **-fg** and **-bg**, respectively. The argument for each option is the color _name_ rather than its ANSI number. For example:
|
|
||||||
|
|
||||||
|
|
||||||
```
|
|
||||||
`$ urxvt -bg black -fg green`
|
|
||||||
```
|
|
||||||
|
|
||||||
These settings set the default foreground and background. Should any other rule govern the color of a specific file or device type, those colors are used. See the [dircolors][5] command for information on how to set those.
|
|
||||||
|
|
||||||
You can also set the color of the text cursor (not the mouse cursor) with **-cr**:
|
|
||||||
|
|
||||||
|
|
||||||
```
|
|
||||||
`$ urxvt -bg black -fg green -cr teal`
|
|
||||||
```
|
|
||||||
|
|
||||||
![Setting color in urxvt][6]
|
|
||||||
|
|
||||||
Your terminal emulator may have more options, like a border color (**-bd** in rxvt), cursor blink (**-bc** and **+bc** in urxvt), and even background transparency. Refer to your terminal's man page to find out what cool features are available.
|
|
||||||
|
|
||||||
To launch your terminal with your choice of colors, you can add the options either to the command or the menu you use to launch the terminal (such as your Fluxbox menu file, a **.desktop** file in **$HOME/.local/share/applications**, or similar). Alternatively, you can use the [xrdb][7] tool to manage X-related resources (but that's out of scope for this article).
|
|
||||||
|
|
||||||
### Home is where the customization is
|
|
||||||
|
|
||||||
Customizing your Linux machine doesn't mean you have to learn how to program. You can and should make small but meaningful changes to make your digital home feel that much more comfortable. And there's no better place to start than the terminal!

更改 Linux 终端颜色主题
|
||||||
|
======
|
||||||
|
你的终端有丰富的选项来来定义你看到的主题。
|
||||||
|
![Terminal command prompt on orange background][1]
|
||||||
|
|
||||||
|
如果你大部分时间都盯着一个终端，那么你很自然地希望它看起来赏心悦目。美与不美，全在观者，终端自 CRT 串口控制台以来已经走了很长一段路。因此，你的软件终端窗口有丰富的选项来定义你看到的主题，不管你如何定义美，这是件好事。
|
||||||
|
|
||||||
|
### 设置
|
||||||
|
|
||||||
|
最受欢迎的软件终端应用，包括GNOME、KDE 和 Xfce，它们都提供了更改其颜色主题的选项。调整主题就像调整应用首选项一样简单。Fedora、RHEL 和 Ubuntu 默认使用 GNOME，因此本文使用该终端作为示例，但 Konsole、Xfce 终端和许多其他终端的流程类似。
|
||||||
|
|
||||||
|
首先，进入到应用的“首选项”或“设置”面板。在 GNOME 终端中，你可以通过屏幕顶部或窗口右上角的“应用”菜单访问它。
|
||||||
|
|
||||||
|
在“首选项”中，单击“配置文件” 旁边的加号 （+） 来创建新的主题配置文件。在新配置文件中，单击“颜色”选项卡。
|
||||||
|
|
||||||
|
![GNOME Terminal preferences][2]
|
||||||
|
|
||||||
|
在“颜色”选项卡中，取消选择“使用系统主题中的颜色”选项，以使窗口的其余部分变为可选状态。最开始，你可以选择内置的颜色方案。这些包括浅色主题，它有明亮的背景和深色的前景文字，还有深色主题，它有深色背景和浅色前景文字。
|
||||||
|
|
||||||
|
当没有其他设置（例如 dircolors 命令的设置）覆盖它们时，“默认颜色”色板将同时定义前景色和背景色。“调色板”设置 dircolors 命令定义的颜色。这些颜色由终端以 LS_COLORS 环境变量的形式使用，以在 [ls][3] 命令的输出中添加颜色。如果它们都不吸引你，请在此更改它们。
|
||||||
|
|
||||||
|
如果对主题感到满意，请关闭“首选项”窗口。
|
||||||
|
|
||||||
|
要将终端更改为新的配置文件，请单击“应用”菜单，然后选择“配置文件”。选择新的配置文件，接着享受自定义主题。
|
||||||
|
|
||||||
|
![GNOME Terminal profile selection][4]
|
||||||
|
|
||||||
|
### 命令选项
|
||||||
|
|
||||||
|
如果你的终端没有不错的设置窗口，它仍然可以在启动命令中提供颜色选项。xterm 和 rxvt 终端（旧的和启用 Unicode 的变体，有时称为 urxvt 或 rxvt-unicode）都提供了这样的选项，因此即使没有桌面环境和大型 GUI 框架，你仍然可以设置终端模拟器的主题。
|
||||||
|
|
||||||
|
两个明显的选项是前景色和背景色，分别用 **-fg** 和 **-bg** 定义。每个选项的参数是颜色_名_而不是它的 ANSI 编号。例如：
|
||||||
|
|
||||||
|
```
|
||||||
|
`$ urxvt -bg black -fg green`
|
||||||
|
```
|
||||||
|
|
||||||
|
这些设置默认的前景和背景。如果任何其他规则控制特定文件或设备类型的颜色，那么就使用这些颜色。有关如何设置它们的信息，请参阅 [dircolors][5] 命令。
|
||||||
|
|
||||||
|
你还可以使用 **-cr** 设置文本光标（而不是鼠标光标）的颜色：
|
||||||
|
|
||||||
|
|
||||||
|
```
|
||||||
|
`$ urxvt -bg black -fg green -cr teal`
|
||||||
|
```
|
||||||
|
|
||||||
|
![Setting color in urxvt][6]
|
||||||
|
|
||||||
|
你的终端模拟器可能有更多选项，如边框颜色（rxvt 中的 **-bd**）、光标闪烁（urxvt 中的 **-bc** 和 **+bc**），甚至背景透明度。请参阅终端的手册页，了解更多的功能。
|
||||||
|
|
||||||
|
要使用你选择的颜色启动终端，你可以将选项添加到用于启动终端的命令或菜单中（例如，在你的 Fluxbox 菜单文件、**$HOME/.local/share/applications** 中的 **.desktop** 或者类似的）。或者，你可以使用 [xrdb][7] 工具来管理与 X 相关的资源（但这超出了本文的范围）。
|
||||||
|
|
||||||
|
### 家是可定制的地方
|
||||||
|
|
||||||
|
自定义 Linux 机器并不意味着你需要学习如何编程。你可以而且应该进行小而有意义的更改，来使你的数字家庭感觉更舒适。而且没有比终端更好的起点了！
