 # ShellJS - Unix shell commands for Node.js [![Build Status](https://secure.travis-ci.org/arturadib/shelljs.png)](http://travis-ci.org/arturadib/shelljs)
 
-+ _This project is young and experimental. Use at your own risk._
-+ _Major API change as of v0.0.4: `ls()` and `find()` now return arrays._
+ShellJS is a portable **(Windows/Linux/OS X)** implementation of Unix shell commands on top of the Node.js API. You can use it to eliminate your shell script's dependency on Unix while still keeping its familiar and powerful commands. You can also install it globally so you can run it from outside Node projects - say goodbye to those gnarly Bash scripts!

-### Example
+## Installing
+
+Via npm:
+
+```bash
+$ npm install [-g] shelljs
+```
+
+If the global option `-g` is specified, the binary `shjs` will be installed. This makes it possible to
+run ShellJS scripts much like any shell script from the command line, i.e. without requiring a `node_modules` folder:
+
+```bash
+$ shjs my_script
+```
+
+You can also just copy `shell.js` into your project's directory, and `require()` accordingly.
+
+
+## Examples

+### JavaScript
 
 ```javascript
 require('shelljs/global');
 
+if (!which('git')) {
+  echo('Sorry, this script requires git');

-### Make tool
+## Make tool
 
 A convenience script `shelljs/make` is also provided to mimic the behavior of a Unix Makefile. In this case all shell objects are global, and command line arguments will cause the script to execute only the corresponding function in the global `target` object. To avoid redundant calls, target functions are executed only once per script.
 
-Example:
-
-```javascript
-//
-// Example file: make.js
-//
-require('shelljs/make');
-
-target.all = function() {
-  target.bundle();
-  target.docs();
-}
-
-// Bundle JS files
-target.bundle = function() {
-  cd(__dirname);
-  mkdir('build');
-  cd('lib');
-  cat('*.js').to('../build/output.js');
-}
-
-// Generate docs
-target.docs = function() {
-  cd(__dirname);
-  mkdir('docs');
-  cd('lib');
-  ls('*.js').forEach(function(file){
-    var text = grep('//@', file); // extract special comments
-    text.replace('//@', ''); // remove comment tags
-    text.to('docs/my_docs.md');
-  });
-}
+Example (CoffeeScript):
+
+```coffeescript
+require 'shelljs/make'
+
+target.all = ->
+  target.bundle()
+  target.docs()
+
+target.bundle = ->
+  cd __dirname
+  mkdir 'build'
+  cd 'lib'
+  (cat '*.js').to '../build/output.js'
+
+target.docs = ->
+  cd __dirname
+  mkdir 'docs'
+  cd 'lib'
+  for file in ls '*.js'
+    text = grep '//@', file     # extract special comments
+    text.replace '//@', ''      # remove comment tags
+    text.to 'docs/my_docs.md'
 ```
 
 To run the target `all`, call the above script without arguments: `$ node make`. To run the target `docs`: `$ node make docs`, and so on.

+Arguments:

++ `+N`: Displays the Nth directory (counting from the left of the list printed by dirs when invoked without options), starting with zero.
++ `-N`: Displays the Nth directory (counting from the right of the list printed by dirs when invoked without options), starting with zero.

+### pushd([options,] [dir | '-N' | '+N'])
+
+Available options:
+
++ `-n`: Suppresses the normal change of directory when adding directories to the stack, so that only the stack is manipulated.
+
+Arguments:
+
++ `dir`: Makes the current working directory be the top of the stack, and then executes the equivalent of `cd dir`.
++ `+N`: Brings the Nth directory (counting from the left of the list printed by dirs, starting with zero) to the top of the list by rotating the stack.
++ `-N`: Brings the Nth directory (counting from the right of the list printed by dirs, starting with zero) to the top of the list by rotating the stack.

+// process.cwd() === '/usr'
+pushd('/etc'); // Returns /etc /usr

+```
+
+Save the current directory on the top of the directory stack and then cd to `dir`. With no arguments, pushd exchanges the top two directories. Returns an array of paths in the stack.

+### popd([options,] ['-N' | '+N'])
+
+Available options:
+
++ `-n`: Suppresses the normal change of directory when removing directories from the stack, so that only the stack is manipulated.

+Arguments:
+
++ `+N`: Removes the Nth directory (counting from the left of the list printed by dirs), starting with zero.
++ `-N`: Removes the Nth directory (counting from the right of the list printed by dirs), starting with zero.

+echo(process.cwd()); // '/etc'
+popd();              // '/usr'
+echo(process.cwd()); // '/usr'
+```
+
+When no arguments are given, popd removes the top directory from the stack and performs a cd to the new top directory. The elements are numbered from 0 starting at the first directory listed with dirs; i.e., popd is equivalent to popd +0. Returns an array of paths in the stack.

 Exits the current process with the given exit code.
 
-#### env['VAR_NAME']
+### env['VAR_NAME']
 Object containing environment variables (both getter and setter). Shortcut to process.env.
 
-#### exec(command [, options] [, callback])
+### exec(command [, options] [, callback])
 Available options (all `false` by default):
 
-+ `async`: Asynchronous execution. Needs callback.
++ `async`: Asynchronous execution. Defaults to true if a callback is provided.
 + `silent`: Do not echo program output to console.
 
 Examples:
 
 ```javascript
 var version = exec('node --version', {silent:true}).output;
+
+var child = exec('some_long_running_process', {async:true});
+child.stdout.on('data', function(data) {
+  /* ... do something with data ... */
+});
+
+exec('some_long_running_process', function(code, output) {
+  console.log('Exit code:', code);
+  console.log('Program output:', output);
+});
 ```
 
 Executes the given `command` _synchronously_, unless otherwise specified.
 When in synchronous mode returns the object `{ code:..., output:... }`, containing the program's
-`output` (stdout + stderr)  and its exit `code`. Otherwise the `callback` gets the 
-arguments `(code, output)`.
+`output` (stdout + stderr)  and its exit `code`. Otherwise returns the child process object, and
+the `callback` gets the arguments `(code, output)`.
 
 **Note:** For long-lived processes, it's best to run `exec()` asynchronously as
 the current synchronous implementation uses a lot of CPU. This should be getting
 fixed soon.
 
-## Non-Unix commands
+### chmod(octal_mode || octal_string, file)
+### chmod(symbolic_mode, file)
 
+Available options:
 
-#### tempdir()
-Searches and returns string containing a writeable, platform-dependent temporary directory.
-Follows Python's [tempfile algorithm](http://docs.python.org/library/tempfile.html#tempfile.tempdir).
++ `-v`: output a diagnostic for every file processed
++ `-c`: like verbose but report only when a change is made
++ `-R`: change files and directories recursively
 
-#### error()
-Tests if error occurred in the last command. Returns `null` if no error occurred,
-otherwise returns string explaining the error
+Examples:
+
+```javascript
+chmod(755, '/Users/brandon');
+chmod('755', '/Users/brandon'); // same as above 
+chmod('u+x', '/Users/brandon');
+```
+
+Alters the permissions of a file or directory by either specifying the
+absolute permissions in octal form or expressing the changes in symbols.
+This command tries to mimic the POSIX behavior as much as possible.
+Notable exceptions:
 
-#### silent([state])
++ In symbolic modes, 'a-r' and '-r' are identical.  No consideration is
+  given to the umask.
++ There is no "quiet" option since default behavior is to run silent.
+
+## Configuration
+
+
+### config.silent
 Example:
 
 ```javascript
-var silentState = silent();
-silent(true);
+var silentState = config.silent; // save old silent state
+config.silent = true;
 /* ... */
-silent(silentState); // restore old silent state
+config.silent = silentState; // restore old silent state
 ```
 
-Suppresses all command output if `state = true`, except for `echo()` calls. 
-Returns state if no arguments given.
-
-## Deprecated
+Suppresses all command output if `true`, except for `echo()` calls.
+Default is `false`.
 
+### config.fatal
+Example:
 
-#### exists(path [, path ...])
-#### exists(path_array)
+```javascript
+config.fatal = true;
+cp('this_file_does_not_exist', '/dev/null'); // dies here
+/* more commands... */
+```
 
-_This function is being deprecated. Use `test()` instead._
+If `true` the script will die on errors. Default is `false`.
 
-Returns true if all the given paths exist.
+## Non-Unix commands
 
-#### verbose()
 
-_This function is being deprecated. Use `silent(false) instead.`_
+### tempdir()
+Searches and returns string containing a writeable, platform-dependent temporary directory.
+Follows Python's [tempfile algorithm](http://docs.python.org/library/tempfile.html#tempfile.tempdir).
 
-Enables all output (default)
+### error()
+Tests if error occurred in the last command. Returns `null` if no error occurred,
+otherwise returns string explaining the error
