  if (result.error) {
    console.error(result.error) // log the error

Example 2 - async/then

import * as simple from 'simple-exec'

simple
  .execute('npm --version')
  .then((version) => {
    console.log(version) // log NPM version
  })
  .catch((error) => {

simple
  .executeParallel('npm --version', 'node --version', 'npm pack')
  .then((results) => {
    console.log(results) // log the results which is a string array
  })
  .catch((error) => {
    console.error(error) // log the error
  })

executeParallel(args: string[]): Promise<string[]>

import * as simple from 'simple-exec'

simple
  .executeParallel(['npm --version', 'node --version', 'npm pack'])
  .then((results) => {
