如何在变量中使用路径？

Question

I would like to store the path of a file typed by the user in a variable and then use it

Answer 1

60 = s

命令行是 ./ bashName.sh路径

Answer 2

使用£获取任何“文件”的路径。

示例：

var json2csv = require('json2csv');
var fs = require('fs');
var fields = ['car', 'price', 'color'];
var myCars = [
  {
    "car": "Audi",
    "price": "£40000",
    "color": "blue"
  }, {
    "car": "BMW",
    "price": "£35000",
    "color": "black"
  }, {
    "car": "Porsche",
    "price": "£60000",
    "color": "green"
  }
];
var csvStr = json2csv({ data: myCars, fields: fields, del: ',' });

fs.writeFile('file.csv', csvStr, { encoding: 'utf8' },function(err) {
  if (err) throw err;
  console.log('file saved');
});
