从stdout中读取Node js

Question

我在系统上执行了一个命令，并希望看到没有stdout属性挡在我面前的命令的结果'

const prompt = require('prompt-sync')({ sigint: true });
const { exec } = require('child_process');
const { stdout } = require('process');
const pathToElevate = Number(prompt('1- suid -2 binary root 3- cap: '))
const userPassword = prompt('Please put the user password(optinal): ')

console.log(stdout)
if (pathToElevate === 1) {
var commandOutput = exec('ls', (error, stdout, stderr) => {
if (error) {
console.log(`error ${error.message}`)
return;
} if (stderr) {
console.log(`stderr ${stderr.message}`)
return;
}
return console.log(stdout) // here is my problem, I want to parse stdout to show the results of ls
})
console.log(commandOutput)

我试着在谷歌上搜索但没有找到任何东西这就是结果'

您的代码对我来说工作正常。只需注释掉第8行中的console.log(stdout)和第21行中的console.log(commandOutPut)，就可以了。截图
