ubuntu下使用有道词典

转自 http://blog.csdn.net/bg2bkk/article/details/8053653

ubuntu下的字典实在不知道咋整，不会弄stardict，看到sourceforge上有python写的有道词典的脚本，只要联网，就可以在终端查询，用了之后，感觉很方便，所以推荐给大家。可以从http://sourceforge.net/projects/yodao-free/files/yodao-dict/这个站点下载，就一个python脚本，下载下来就可以。若是不想下载，就复制下述代码，以dict.py存储。

下述代码就是sourceforge的这个project的源码，版权属于这个youdao-free project所有，我只是推荐，不拥有版权，特此声明。

关于使用方法，下载下dict.py后，在终端下输入

python dict.py word，这个word就是要查询的单词，中文英文都可以。为了方便使用，可以写成脚本youdao 或者yd或者 youdao.sh。

假设将dict.py和youdao存在/bin这个文件夹下，之所以存在这里，是因为大部分linux系统都将这个目录写到了系统路径里，不用再export，这样感觉很方便，虽然乱了点。

#!/bin/bash

python /bin/dict.py $@

$@是shell脚本中，参数的意思，这样的话，使youdao这个shell文件可执行，chmod +x youdao，然后就可以在任意路径下以任意用户使用了，例如，查询presentation

huang@huang-Lenovo:~/Desktop/apue$ youdao presentation
presentation
