Shelljs: how to cancel async process?

Question

Given I do something like:

shelljs.exec('someLongrunningCommand', {async: true})

How can I send a SIGINT or otherwise cancel this process in the same script?

Answer 1

You can cancel the process by sending a SIGINT or SIGHUP signal with subprocess.kill() methods like this:

const shell = require('shelljs');

let process = shell.exec('someLongrunningCommand', { async: true });

// Here you stop the process
process.kill('SIGINT');
