ubuntu安装有道词典命令行查询

1.第三方安装 

# 安装npm
wget https://nodejs.org/dist/v6.9.5/node-v6.9.5-linux-x64.tar.xz
tar -xvf node-v6.9.5-linux-x64.tar.xz
sudo mv node-v6.9.5-linux-x64 /usr/local/node
sudo ln -s /usr/local/node/bin/node /usr/local/bin/node
sudo ln -s /usr/local/node/lib/node_modules/npm/bin/npm-cli.js /usr/local/bin/npm
# 安装有道
npm install yddict -g

# 配置
ln -s  /usr/local/node/lib/node_modules/yddict/index.js /usr/local/bin/yd

使用：

yd love

默认字体颜色为白色。

我的肢体是白色，结果看不清了：

改成黑色：在/usr/local/node/lib/node_modules/yddict/index.js  将config.color直接改成‘black’，保存即可。

2.python脚本安装

找一个合适的地方存放脚本：（youdao.py）

我的路径在：/usr/xxx/youdao.py

 在～/下创建脚本youdao，

#!/bin/bash
while [ $# -ne 0 ]
do
	python /usr/xxx/youdao.py $1 #你的脚本路径
	shift
done

基于权限chmod u+x youdao

但是我们为了方便。那就将这个脚本链接到/usr/bin 下。

sudo ln -s ~/youdao /usr/bin/yd

大功告成，可以查句子、单词、汉译英、英译汉(有点不友好，空格没法识别，可以将空格换成“_”)：
