node execute node run code example

Example 1: node run shell command

// You can use 'exec' this way

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

exec("ls -la", (error, stdout, stderr) => {
    if (error) {
        console.log(`error: ${error.message}`);
        return;
    }
    if (stderr) {
        console.log(`stderr: ${stderr}`);
        return;
    }
    console.log(`stdout: ${stdout}`);
});

Example 2: javascript run command

const { execSync } = require('child_process');

const output = execSync('ls', { encoding: 'utf-8' });

console.log('The output is:');
console.log(output);
