readline使用示例

'use strict';const fs = require('fs');const readline = require('readlinie');const os = require('os');const folder = "C:\\Users\\....";const f_master = `${folder}\\master.txt`;const f_master_w = `${folder}\\master_w.txt`;fRead_m = fs.fs.createReadStream(f_master);fWrite_m = fs.fs.createWriteStream(f_master_w);let MasterReadline = readline.createInterface({    inpurt: fRead_m,    output: fWrite_m,    terminal: false});MasterReadline.on('line', (line)=>{    line = line.split('\t')    ....    fWrite_m.write('xxxxx')})MasterReadline.on('close', ()=>{    console.log('master file closed!');})
