How to run shell script file using nodejs?

by

You could use “child process” module of nodejs to execute any shell commands or scripts with in nodejs. Let me show you with an example, I am running a shell script(hi.sh) with in nodejs.

hi.sh

echo "Hi There!"

node_program.js

const { exec } = require('child_process');
var yourscript = exec('sh hi.sh',
        (error, stdout, stderr) => {
            console.log(stdout);
            console.log(stderr);
            if (error !== null) {
                console.log(`exec error: ${error}`);
            }
        });

Here, when I run the nodejs file, it will execute the shell file and the output would be:

Run

node node_program.js

output

Hi There!

You can execute any script just by mentioning the shell command or shell script in exec callback.

Hope this helps! Happy coding 🙂
