Would you like to clone this notebook?
When you clone a notebook you are able to make changes without affecting the original notebook.
spawn() spawns a new process using the given command, with any command line arguments passed into an array.
Unlike exec(), no extra shell gets spawned, so that output is not buffered, but caught via event handlers.
// Require necessary modules
const childProcess = require('child_process');
const os = require('os');
// Show OS/kernel version
console.log(`Kernel version: ${os.release()}`);
// Show current working directory (CWD)
console.log(`CWD: ${process.cwd()}`);
Now creating instance of child_process.spawn()
Goal is to show the contents of the root directory using native 'ls'-command.
const ls = childProcess.spawn('ls', ['-lh', '/']);
Listening for console output events below:
ls.stdout.on('data', output => console.log(`Info: ${output}`)); // Normal output
ls.stderr.on('data', err => console.error(`Error: ${err}`)); // Error output
Listening for 'close' event below, this event is fired whenever the child process was closed/killed.
ls.on('close', code => console.log(`Child process closed with code ${code}`));
