命令行快捷搜索internet的方法
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
以下是源代码:
#!/bin/sh
