+# grunt-shell [![Build Status](https://travis-ci.org/sindresorhus/grunt-shell.svg?branch=master)](https://travis-ci.org/sindresorhus/grunt-shell)
+
+> Run shell commands
+
+A good way to interact with other CLI tools. E.g. compiling Compass `compass compile` or get the current git branch `git branch`.
+
+**Use [StackOverflow](http://stackoverflow.com/questions/tagged/gruntjs) for support questions.**
+
+
+## Install
+
+```sh
+$ npm install --save-dev grunt-shell
+```
+
+
+## Usage
+
+```js
+require('load-grunt-tasks')(grunt); // npm install --save-dev load-grunt-tasks
+
+grunt.initConfig({
+	shell: {
+		options: {
+			stderr: false
+		},
+		target: {
+			command: 'ls'
+		}
+	}
+});
+
+grunt.registerTask('default', ['shell']);
+```
+
+
+## Examples
+
+### Run command
+
+Create a folder named `test`.
+
+```js
+grunt.initConfig({
+	shell: {
+		makeDir: {
+			command: 'mkdir test'
+		}
+	}
+});
+```
+
+The `command` property supports templates:
+
+```js
+grunt.initConfig({
+	testDir: 'test',
+	shell: {
+		makeDir: {
+			command: 'mkdir <%= testDir %>'
+		}
+	}
+});
+```
+
+You can also supply a function that returns the command:
+
+```js
+grunt.initConfig({
+	shell: {
+		hello: {
+			command: function () {
+				return 'echo hello';
+			}
+		}
+	}
+});
+```
+
+Which can also take arguments:
+
+```js
+module.exports = function(grunt) {
+	grunt.loadNpmTasks('grunt-shell');
+	grunt.initConfig({
+		shell: {
+			greet: {
+				command: function (greeting) {
+					return 'echo ' + greeting;
+				}
+			}
+		}
+	});
+	grunt.registerTask('default', ['shell:greet:hello']);
+}
+```
+
+### Run command and display the output
+
+Output a directory listing in your Terminal.
+
+```js
+grunt.initConfig({
+	shell: {
+		dirListing: {
+			command: 'ls'
+		}
+	}
+});
+```
+
+### Custom callback
+
+Do whatever you want with the output.
+
+```js
+function log(err, stdout, stderr, cb) {
+	console.log(stdout);
+	cb();
+}
+
+grunt.initConfig({
+	shell: {
+		dirListing: {
+			command: 'ls',
+			options: {
+				callback: log
+			}
+		}
+	}
+});
+```
+
+### Option passed to the .exec() method
+
+Run a command in another directory. In this example we run it in a subfolder using the `cwd` (current working directory) option.
+
+```js
+grunt.initConfig({
+	shell: {
+		subfolderLs: {
+			command: 'ls',
+			options: {
+				stderr: false,
+				execOptions: {
+					cwd: 'tasks'
+				}
+			}
+		}
+	}
+});
+```
+
+### Multiple commands
+
+Run multiple commands by placing them in an array which is joined using `&&` or `;`. `&&` means run this only if the previous command succeeded. You can also use `&` to have the commands run concurrently (by executing all commands except the last one in a subshell).
+
+```js
+grunt.initConfig({
+	shell: {
+		multiple: {
+			command: [
+				'mkdir test',
+				'cd test',
+				'ls'
+			].join('&&')
+		}
+	}
+});
+```
+
+
+## Config
+
+### command
+
+*Required*  
+Type: `string`, `function`
+
+The command you want to run or a function which returns it. Supports underscore templates.
+
+## Options
+
+### stdout
+
+Type: `boolean`  
+Default: `true`
+
+Show stdout in the Terminal.
+
+### stderr
+
+Type: `boolean`  
+Default: `true`
+
+Show stderr in the Terminal.
+
+### stdin
+
+Type: `boolean`  
+Default: `true`
+
+Forward the terminal's stdin to the command.
+
+### failOnError
+
+Type: `boolean`  
+Default: `true`
+
+Fail task if it encounters an error. Does not apply if you specify a `callback`.
+
+### stdinRawMode
+
+Type: `boolean`  
+Default: `false`
+
+This sets `stdin` to [act as a raw device](http://nodejs.org/api/tty.html#tty_rs_setrawmode_mode).
+
+### callback(err, stdout, stderr, cb)
+
+Type: `function`  
+Default: `function () {}`
+
+Lets you override the default callback with your own.
+
+**Make sure to call the `cb` method when you're done.**
+
+### execOptions
+
+Type: `object`
+
+Specify some options to be passed to the [.exec()](http://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback) method:
+
+- `cwd` String *Current working directory of the child process*
+- `env` Object *Environment key-value pairs*
+- `setsid` Boolean
+- `encoding` String *(Default: 'utf8')*
+- `timeout` Number *(Default: 0)*
+- `maxBuffer` Number *(Default: 200\*1024)*
+- `killSignal` String *(Default: 'SIGTERM')*
