命令行快捷搜索internet

Posted 2021-05-16 redguardtoo

firefox中有个功能很有用，就是输入g然后后面加上要搜索的关键字，就可以自动到google上搜索。这个功能叫QuickSearch。

我希望在命令行下也有这个功能，所以自己写了名为search的bash script。可以在命令行中直接调用文本界面的浏览器搜索（例如w3m或者lynx).

使用方法如下:
在google中搜索关键字:
$search g keyword [keyword]...

在google blogsearch中搜索关键字:
$search b keyword [keyword]...

查辞典:
$search d keyword

如果你设置好alias（实际上search会帮你做得）：
那么上面的的三种搜索可以简化为
$g keyword [keyword]...
$b keyword [keyword]...
$d keyword

搜索引擎是可以定制的，定制的过程及其简单，和firefox的QuickSearch的设置没有区别。


将search安装到/usr/bin目录:
$search install

输出设置alias的脚本到标准输出:
$search mkalias

典型的安装过程:
$su
$search install;exit
$search mkalias >> ~/.bashrc; source ~/.bashrc
