+
+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 `<v4.8`
+
+All these issues are handled correctly by `cross-spawn`.
+There are some known modules, such as [win-spawn](https://github.com/ForbesLindesay/win-spawn), that try to solve this but they are either broken or provide faulty escaping of shell arguments.
+
+
+## Usage
+
+Exactly the same way as node's [`spawn`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options) or [`spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options), so it's a drop in replacement.
+
+
+```js
+const spawn = require('cross-spawn');
+
+// Spawn NPM asynchronously
+const child = spawn('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
+
+// Spawn NPM synchronously
+const result = spawn.sync('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
+```
+
+
+## Caveats
+
+### Using `options.shell` as an alternative to `cross-spawn`
+
+Starting from node `v4.8`, `spawn` has a `shell` option that allows you run commands from within a shell. This new option solves
+the [PATHEXT](https://github.com/joyent/node/issues/2318) issue but:
+
+- It's not supported in node `<v4.8`
+- You must manually escape the command and arguments which is very error prone, specially when passing user input
+- There are a lot of other unresolved issues from the [Why](#why) section that you must take into account
+
+If you are using the `shell` option to spawn a command in a cross platform way, consider using `cross-spawn` instead. You have been warned.
+
+### `options.shell` support
+
+While `cross-spawn` adds support for `options.shell` in node `<v4.8`, all of its enhancements are disabled.
+
+This mimics the Node.js behavior. More specifically, the command and its arguments will not be automatically escaped nor shebang support will be offered. This is by design because if you are using `options.shell` you are probably targeting a specific platform anyway and you don't want things to get into your way.
+
+### Shebangs support
+
+While `cross-spawn` handles shebangs on Windows, its support is limited. More specifically, it just supports `#!/usr/bin/env <program>` where `<program>` 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

+# isexe
+
+Minimal module to check if a file is executable, and a normal file.
+
+Uses `fs.stat` and tests against the `PATHEXT` environment variable on
+Windows.
+
+## USAGE
+
+```javascript
+var isexe = require('isexe')
+isexe('some-file-name', function (err, isExe) {
+  if (err) {
+    console.error('probably file does not exist or something', err)
+  } else if (isExe) {
+    console.error('this thing can be run')
+  } else {
+    console.error('cannot be run')
+  }
+})
+
+// same thing but synchronous, throws errors
+var isExe = isexe.sync('some-file-name')
+
+// treat errors as just "not executable"
+isexe('maybe-missing-file', { ignoreErrors: true }, callback)
+var isExe = isexe.sync('maybe-missing-file', { ignoreErrors: true })
+```
+
+## API
+
+### `isexe(path, [options], [callback])`
+
+Check if the path is executable.  If no callback provided, and a
+global `Promise` object is available, then a Promise will be returned.
+
+Will raise whatever errors may be raised by `fs.stat`, unless
+`options.ignoreErrors` is set to true.
+
+### `isexe.sync(path, [options])`
+
+Same as `isexe` but returns the value and throws any errors raised.
+
+### Options
+
+* `ignoreErrors` Treat all errors as "no, this is not executable", but
+  don't raise them.
+* `uid` Number to use as the user id
+* `gid` Number to use as the group id
+* `pathExt` List of path extensions to use instead of `PATHEXT`
+  environment variable on Windows.

+# which
+
+Like the unix `which` utility.
+
+Finds the first instance of a specified executable in the PATH
+environment variable.  Does not cache the results, so `hash -r` is not
+needed when the PATH changes.
+
+## USAGE
+
+```javascript
+var which = require('which')
+
+// async usage
+which('node', function (er, resolvedPath) {
+  // er is returned if no "node" is found on the PATH
+  // if it is found, then the absolute path to the exec is returned
+})
+
+// or promise
+which('node').then(resolvedPath => { ... }).catch(er => { ... not found ... })
+
+// sync usage
+// throws if not found
+var resolved = which.sync('node')
+
+// if nothrow option is used, returns null if not found
+resolved = which.sync('node', {nothrow: true})
+
+// Pass options to override the PATH and PATHEXT environment vars.
+which('node', { path: someOtherPath }, function (er, resolved) {
+  if (er)
+    throw er
+  console.log('found at %j', resolved)
+})
+```
+
+## CLI USAGE
+
+Same as the BSD `which(1)` binary.
+
+```
+usage: which [-as] program ...
+```
+
+## OPTIONS
+
+You may pass an options object as the second argument.
+
+- `path`: Use instead of the `PATH` environment variable.
+- `pathExt`: Use instead of the `PATHEXT` environment variable.
+- `all`: Return all matches, instead of just the first one.  Note that
+  this means the function returns an array of strings instead of a
+  single string.
