@alphahydrae/exec NPM

`@alphahydrae/exec`

The execvp function for Node.js.

import { execvp } from '@alphahydrae/exec';

execvp('ls', ['.']);

console.log(`
  This will never print because the executing Node.js
  program is replaced by the executed command, keeping
  the same process ID and file descriptors.
`);

If you're familiar with Bash's exec function, this is the same for Node.js.

This package was developed to be used in Node.js scripts that are frontends to execute other commands. For example, a script that would build and execute a complex SSH or Ansible command.

Installation

npm i @alphahydrae/exec
