越努力，越幸运

一、fs.cp()

---

const Fs = require("fs");
const Path = require("path");

const ignoreFileExtList = [".DS_Store", ".txt"];
const sourcePath = "/Users/zhangwenqiang/bolawen/scripts/test/a";
const targetPath = "/Users/zhangwenqiang/bolawen/scripts/test/e";

function copy(sourcePath, targetPath) {
  return new Promise((resolve, reject) => {
    Fs.cp(
      sourcePath,
      targetPath,
      {
        force: true,
        recursive: true,
        filter(src, desc) {
          const pathInfo = Path.parse(src);
          if (ignoreFileExtList.includes(pathInfo.ext)) {
            return false;
          }
          return true;
        },
      },
      (error) => {
        if (error) {
          return resolve(false);
        }
        resolve(true);
      }
    );
  });
}

copy(sourcePath, targetPath);

二、child_process.exec

---

const { exec } = require("child_process");

const sourcePath = "/Users/zhangwenqiang/bolawen/scripts/test/a";
const targetPath = "/Users/zhangwenqiang/bolawen/scripts/test/e";

function execCmd(...args) {
  return new Promise((resolve) => {
    exec(args.join(" "), (error, stdout, stderr) => {
      if (error) {
        return resolve(false);
      }
      resolve(true);
    });
  });
}

async function copy(sourcePath, targetPath) {
  await execCmd("cp", "-r", sourcePath, targetPath);
}

copy(sourcePath, targetPath);

三、child_process.spawn

---

const { spawn } = require("child_process");
const sourcePath = "/Users/zhangwenqiang/bolawen/scripts/test/a";
const targetPath = "/Users/zhangwenqiang/bolawen/scripts/test/e";

function spawnCmd(...args) {
  return new Promise((resolve) => {
    const childProcess = spawn(...args);
    childProcess.stdout.pipe(process.stdout);
    childProcess.stdout.pipe(process.stderr);
    childProcess.on("close", () => {
      resolve();
    });
  });
}

async function copy(sourcePath, targetPath) {
  await spawnCmd("cp", ["-r", sourcePath, targetPath]);
}

copy(sourcePath, targetPath);
