A cross platform solution to node's spawn and spawnSync.

## Installation

Node.js version 8 and up:

`$ npm install cross-spawn`

Node.js version 7 and under:

`$ npm install cross-spawn@6`

## Why

Node has issues when using spawn on Windows:

- It ignores [PATHEXT](https://github.com/joyent/node/issues/2318)

- It does not support [shebangs](https://en.wikipedia.org/wiki/Shebang_(Unix))

- Has problems running commands with [spaces](https://github.com/nodejs/node/issues/7367)

- Has problems running commands with posix relative paths (e.g.: `./my-folder/my-executable`)

- Has an [issue](https://github.com/moxystudio/node-cross-spawn/issues/82) with command shims (files in `node_modules/.bin/`), where arguments with quotes and parenthesis would result in [invalid syntax error](https://github.com/moxystudio/node-cross-spawn/blob/e77b8f22a416db46b6196767bcd35601d7e11d54/test/index.test.js#L149)

- No `options.shell` support on node `` where `` must not contain any arguments.   

If you would like to have the shebang support improved, feel free to contribute via a pull-request.

Remember to always test your code on Windows!

## Tests

`$ npm test`   

`$ npm test -- --watch` during development
