linux下方便的使用有道詞典

直接上圖，覺得合適就用，想查單詞時，復制單詞粘貼到終端，非常方便。不要騙自己說你想知道音標，想知道詳細的例句，大多時候我們是只需要快速知道這個單詞的意思。實現方法是大牛實現的，使用python調用有道的接口，但我忘記出處了，抱歉！

我也折騰過有道詞典的安裝，後來安裝好了，但體驗非常差，之前是占用資源巨多，後來換了個高配的筆記本，還是感覺不好用。奉勸在折騰的同學一句，不要在折騰有道詞典的安裝。ubuntu上安裝還挺方便的，centos上安裝這詞典真心不容易。我現在直接使用終端查單詞，浏覽器直接使用有道的翻譯插件。挺方便的！

youdao終端查單詞其實很簡單，就幾行python代碼，我直接貼上來吧，復制代碼並在/usr/local/bin下建個可執行文件就可以使用了。

粘貼如下代碼：

[code]#!/bin/bash
python /usr/local/bin/dict.py $1;
echo -n "input:";
while read input;
do
    python /usr/local/bin/dict.py ${input};
    echo -n "input:";
done

最後一步，給文件添加可執行權限：

[code] sudo chmod + x /usr/local/bin/dict.py
 sudo chmod + x /usr/local/bin/youdao

[code]youdao  english

祝好運！！
