Nodejs shell like programming: calling an external command and returning output to stdout

wget.js

#! env node

// execFileSync will call the command directly without using a shell, a tad faster and prevents interpretation of characters
// ( similar to C and java exec )
const exec = require('child_process').execFileSync;
// inherit will use the stdio of the parent process, ie this nodejs script
exec('wget', ['https://git.kernel.org/torvalds/t/linux-4.18-rc8.tar.gz', '--output-document', '/tmp/bla'], {stdio:'inherit'});
