#!/usr/bin/env zx

await $`cat package.json | grep name`

const branch = await $`git branch --show-current`
await $`dep deploy --branch=${branch}`

await Promise.all([
  $`sleep 1; echo 1`,
  $`sleep 2; echo 2`,
  $`sleep 3; echo 3`,
])

const name = 'foo bar'
await $`mkdir /tmp/${name}`

Bash is great, but when it comes to writing more complex scripts, many people prefer a more convenient programming language. JavaScript is a perfect choice, but the Node.js standard library requires additional hassle before using. No compromise, take the best of both. The zx package provides useful cross-platform wrappers around child_process, escapes arguments and gives sensible defaults.

Install
