program
.command('generate')
.description('quick generate your file')
.alias('g')
.action(function(type, name){
xu.run(type, name);
});
program.parse(process.argv);
这就是功能命令，定义了一个generate命令，.alias(‘g’)是该命令的缩写，然后.action(function(type, name){xu.run(type, name); });返回一个函数，这个函数就是我们定义这个命令需要做什么事。
编写功能函数
./src/generate.js
这个文件就定义了当我们输入
$ xu g所做的操作了。
