ddgr – A Command Line Tool To Search DuckDuckGo From The Terminal
|
||||
======
|
||||
Bash tricks are really awesome in Linux that makes everything is possible in Linux.
|
||||
|
||||
It really works well for developers or system admins because they are spending most of the time with terminal. Did you know why they are preferring this tricks?
|
||||
|
||||
These trick will improve their productivity and also make them to work fast.
|
||||
|
||||
### What Is ddgr
|
||||
|
||||
[ddgr][1] is a command-line utility to search DuckDuckGo from the terminal. ddgr works out of the box with several text-based browsers if the BROWSER environment variable is set.
|
||||
|
||||
Make sure your system should have installed any text-based browsers. You may know about [googler][2] that allow users to perform Google searches from the Linux command line.
|
||||
|
||||
It’s highly popular among cmdline users and they are expect the similar utility for privacy-aware DuckDuckGo, that’s why ddgr came to picture.
|
||||
|
||||
Unlike the web interface, you can specify the number of search results you would like to see per page.

||||

### What Is DuckDuckGo
|
||||
|
||||
DDG stands for DuckDuckGo. DuckDuckGo (DDG) is an Internet search engine that really protecting users search and privacy.

They didn’t filter users personalized search results and It’s showing the same search results to all users for a given search term.

ddgr - 一个从终端搜索 DuckDuckGo 的命令行工具
|
||||
======
|
||||
在 Linux 中，Bash 技巧非常棒，它使 Linux 中的一切成为可能。
|
||||
|
||||
对于开发人员或系统管理员来说，它真的很管用，因为他们大部分时间都在使用终端。你知道他们为什么喜欢这种技巧吗？
|
||||
|
||||
因为这些技巧可以提高他们的工作效率，也能使他们工作更快。
|
||||
|
||||
### 什么是 ddgr
|
||||
|
||||
[ddgr][1] 是一个命令行实用程序，用于从终端搜索 DuckDuckGo。如果设置了 BROWSER 环境变量，ddgr 可以在几个基于文本的浏览器中开箱即用。
|
||||
|
||||
确保你的系统安装了任何基于文本的浏览器。你可能知道 [googler][2]，它允许用户从 Linux 命令行进行 Google 搜索。
|
||||
|
||||
它在命令行用户中非常受欢迎，他们期望对隐私敏感的 DuckDuckGo 也有类似的实用程序，这就是 ddgr 出现的原因。
|
||||
|
||||
与 Web 界面不同，你可以指定每页要查看的搜索结果数。
|
||||
|
||||
**建议阅读：**

||||

|
||||
**(#)** [RTV（Reddit 终端查看器）- 一个简单的 Reddit 终端查看器][5]
|
||||
|
||||
### 什么是 DuckDuckGo
|
||||
|
||||
DDG 即 DuckDuckGo。DuckDuckGo（DDG）是一个真正保护用户搜索和隐私的互联网搜索引擎。
|
||||
|
||||
它们没有过滤用户的个性化搜索结果，对于给定的搜索词，它会向所有用户显示相同的搜索结果。
|
||||
|
||||
大多数用户更喜欢谷歌搜索引擎，但是如果你真的担心隐私，那么你可以放心地使用 DuckDuckGo。
|
||||
|
||||
### ddgr 特性
|
||||
|
||||
* 快速且干净（没有广告，多余的 URL 或杂物），自定义颜色
|
||||
* 旨在以最小的空间提供最高的可读性
|
||||
* 指定每页显示的搜索结果数
|
||||
* 从浏览器中打开的 omniprompt URL 导航结果页面
|
||||
* Bash、Zsh 和 Fish 的搜索和配置脚本
|
||||
* DuckDuckGo Bang 支持（自动完成）
|
||||
* 直接在浏览器中打开第一个结果（就像我感觉 Ducky）
|
||||
* 不间断搜索：无需退出即可在 omniprompt 中触发新搜索
|
||||
* 关键字支持（例如：filetype:mime、site:somesite.com）
|
||||
* 按时间、指定区域、禁用安全搜索
|
||||
* HTTPS 代理支持，无跟踪，可选择禁用用户代理
|
||||
* 支持自定义 URL 处理程序脚本或命令行实用程序
|
||||
* 全面的文档，man 页面有方便的使用示例
|
||||
* 最小的依赖关系
|
||||
|
||||
|
||||

|
||||
|
||||
直接从终端：
|
||||
```
|
||||
$ ddgr 2daygeek
|
||||
|
||||
```

||||
|
||||
![][17]

||||
|
||||
从 `omniprompt`：
|
||||
![][18]
|
||||
|
||||
### Omniprompt 快捷方式
|
||||
|
||||
输入 `?` 以获得 `omniprompt`，它将显示关键字列表和进一步使用 ddgr 的快捷方式。
|
||||
![][19]
|
||||
|
||||
### 如何移动下一页、上一页和第一页
|
||||
|
||||
它允许用户移动下一页、上一页或第一页。
|
||||
|
||||
* `n:` 移动到下一组搜索结果
|
||||

|
||||
* `f:` 跳转到第一页
|
||||
|
||||
![][20]
|
||||
|
||||
### 如何启动新搜索
|
||||
|
||||
“**d**” 选项允许用户从 omniprompt 发起新的搜索。例如，我搜索了 `2daygeek 网站`，现在我将搜索 **Magesh Maruthamuthu** 这个新短语。
|
||||
|
||||
从 `omniprompt`.
|
||||
```
|
||||
ddgr (? for help) d magesh maruthmuthu
|
||||
|
||||
```
|
||||
|
||||
![][21]
|
||||
|
||||
### 在搜索结果中显示完整的 URL
|
||||
|
||||
默认情况下，它仅显示文章标题，在搜索中添加 **x** 选项以在搜索结果中显示完整的文章网址。
|
||||
```
|
||||
$ ddgr -n 5 -x 2daygeek
|
||||
|
||||
```
|
||||
|
||||
![][22]
|
||||
|
||||
### 限制搜索结果
|
||||
|
||||
默认情况下，搜索结果每页显示 10 个结果。如果你想为方便起见限制页面结果，可以使用 ddgr 带有 `--num` 或 ` -n` 参数。
|
||||
```
|
||||
$ ddgr -n 5 2daygeek
|
||||
|
||||
```
|
||||
|
||||
![][23]
|
||||
|
||||
### 网站特定搜索
|
||||
|
||||
要搜索特定网站的特定页面，使用以下格式。这将从网站获取给定关键字的结果。例如，我们在 2daygeek 网站搜索 **Package Manager**，查看结果。
|
||||
```
|
||||
$ ddgr -n 5 --site 2daygeek "package manager"
|
||||
|
||||
```
