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!\n\nThe project is [unit-tested](http://travis-ci.org/arturadib/shelljs) and battled-tested in projects like:\n\n+ [PDF.js](http://github.com/mozilla/pdf.js) - Firefox's next-gen PDF reader\n+ [Firebug](http://getfirebug.com/) - Firefox's infamous debugger\n+ [JSHint](http://jshint.com) - Most popular JavaScript linter\n+ [Zepto](http://zeptojs.com) - jQuery-compatible JavaScript library for modern browsers\n+ [Yeoman](http://yeoman.io/) - Web application stack and d
 evelopment tool\n+ [Deployd.com](http://deployd.com) - Open source PaaS for quick API backend generation\n\nand [many more](https://npmjs.org/browse/depended/shelljs).\n\n## Installing\n\nVia npm:\n\n```bash\n$ npm install [-g] shelljs\n```\n\nIf the global option `-g` is specified, the binary `shjs` will be installed. This makes it possible to\nrun ShellJS scripts much like any shell script from the command line, i.e. without requiring a `node_modules` folder:\n\n```bash\n$ shjs my_script\n```\n\nYou can also just copy `shell.js` into your project's directory, and `require()` accordingly.\n\n\n## Examples\n\n### JavaScript\n\n```javascript\nrequire('shelljs/global');\n\nif (!which('git')) {\n  echo('Sorry, this script requires git');\n  exit(1);\n}\n\n// Copy files to release dir\nmkdir('-p', 'out/Release');\ncp('-R', 'stuff/*', 'out/Release');\n\n// Replace macros in each .js file\ncd('lib');\nls('*.js').forEach(function(file) {\n  sed('-i', 'BUILD_VERSION', 'v0.1.2', file);\n  se
 d('-i', /.*REMOVE_THIS_LINE.*\\n/, '', file);\n  sed('-i', /.*REPLACE_LINE_WITH_MACRO.*\\n/, cat('macro.js'), file);\n});\ncd('..');\n\n// Run external tool synchronously\nif (exec('git commit -am \"Auto-commit\"').code !== 0) {\n  echo('Error: Git commit failed');\n  exit(1);\n}\n```\n\n### CoffeeScript\n\n```coffeescript\nrequire 'shelljs/global'\n\nif not which 'git'\n  echo 'Sorry, this script requires git'\n  exit 1\n\n# Copy files to release dir\nmkdir '-p', 'out/Release'\ncp '-R', 'stuff/*', 'out/Release'\n\n# Replace macros in each .js file\ncd 'lib'\nfor file in ls '*.js'\n  sed '-i', 'BUILD_VERSION', 'v0.1.2', file\n  sed '-i', /.*REMOVE_THIS_LINE.*\\n/, '', file\n  sed '-i', /.*REPLACE_LINE_WITH_MACRO.*\\n/, cat 'macro.js', file\ncd '..'\n\n# Run external tool synchronously\nif (exec 'git commit -am \"Auto-commit\"').code != 0\n  echo 'Error: Git commit failed'\n  exit 1\n```\n\n## Global vs. Local\n\nThe example above uses the convenience script `shelljs/global` to reduc
 e verbosity. If polluting your global namespace is not desirable, simply require `shelljs`.\n\nExample:\n\n```javascript\nvar shell = require('shelljs');\nshell.echo('hello world');\n```\n\n## Make tool\n\nA 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.\n\nExample (CoffeeScript):\n\n```coffeescript\nrequire 'shelljs/make'\n\ntarget.all = ->\n  target.bundle()\n  target.docs()\n\ntarget.bundle = ->\n  cd __dirname\n  mkdir 'build'\n  cd 'lib'\n  (cat '*.js').to '../build/output.js'\n\ntarget.docs = ->\n  cd __dirname\n  mkdir 'docs'\n  cd 'lib'\n  for file in ls '*.js'\n    text = grep '//@', file     # extract special comments\n    text.replace '//@', ''      # remove comment tags\n    text.to 'do
 cs/my_docs.md'\n```\n\nTo run the target `all`, call the above script without arguments: `$ node make`. To run the target `docs`: `$ node make docs`, and so on.\n\n\n\n<!-- \n\n  DO NOT MODIFY BEYOND THIS POINT - IT'S AUTOMATICALLY GENERATED\n\n-->\n\n\n## Command reference\n\n\nAll commands run synchronously, unless otherwise stated.\n\n\n### cd('dir')\nChanges to directory `dir` for the duration of the script\n\n### pwd()\nReturns the current directory.\n\n### ls([options ,] path [,path ...])\n### ls([options ,] path_array)\nAvailable options:\n\n+ `-R`: recursive\n+ `-A`: all files (include files beginning with `.`, except for `.` and `..`)\n\nExamples:\n\n```javascript\nls('projs/*.js');\nls('-R', '/users/me', '/tmp');\nls('-R', ['/users/me', '/tmp']); // same as above\n```\n\nReturns array of files in the given path, or in current directory if no path provided.\n\n### find(path [,path ...])\n### find(path_array)\nExamples:\n\n```javascript\nfind('src', 'lib');\nfind(['src', 'li
 b']); // same as above\nfind('.').filter(function(file) { return file.match(/\\.js$/); });\n```\n\nReturns array of all files (however deep) in the given paths.\n\nThe main difference from `ls('-R', path)` is that the resulting file names\ninclude the base directories, e.g. `lib/resources/file1` instead of just `file1`.\n\n### cp([options ,] source [,source ...], dest)\n### cp([options ,] source_array, dest)\nAvailable options:\n\n+ `-f`: force\n+ `-r, -R`: recursive\n\nExamples:\n\n```javascript\ncp('file1', 'dir1');\ncp('-Rf', '/tmp/*', '/usr/local/*', '/home/tmp');\ncp('-Rf', ['/tmp/*', '/usr/local/*'], '/home/tmp'); // same as above\n```\n\nCopies files. The wildcard `*` is accepted.\n\n### rm([options ,] file [, file ...])\n### rm([options ,] file_array)\nAvailable options:\n\n+ `-f`: force\n+ `-r, -R`: recursive\n\nExamples:\n\n```javascript\nrm('-rf', '/tmp/*');\nrm('some_file.txt', 'another_file.txt');\nrm(['some_file.txt', 'another_file.txt']); // same as above\n```\n\nRemo
 ves files. The wildcard `*` is accepted.\n\n### mv(source [, source ...], dest')\n### mv(source_array, dest')\nAvailable options:\n\n+ `f`: force\n\nExamples:\n\n```javascript\nmv('-f', 'file', 'dir/');\nmv('file1', 'file2', 'dir/');\nmv(['file1', 'file2'], 'dir/'); // same as above\n```\n\nMoves files. The wildcard `*` is accepted.\n\n### mkdir([options ,] dir [, dir ...])\n### mkdir([options ,] dir_array)\nAvailable options:\n\n+ `p`: full path (will create intermediate dirs if necessary)\n\nExamples:\n\n```javascript\nmkdir('-p', '/tmp/a/b/c/d', '/tmp/e/f/g');\nmkdir('-p', ['/tmp/a/b/c/d', '/tmp/e/f/g']); // same as above\n```\n\nCreates directories.\n\n### test(expression)\nAvailable expression primaries:\n\n+ `'-b', 'path'`: true if path is a block device\n+ `'-c', 'path'`: true if path is a character device\n+ `'-d', 'path'`: true if path is a directory\n+ `'-e', 'path'`: true if path exists\n+ `'-f', 'path'`: true if path is a regular file\n+ `'-L', 'path'`: true if path is a
  symboilc link\n+ `'-p', 'path'`: true if path is a pipe (FIFO)\n+ `'-S', 'path'`: true if path is a socket\n\nExamples:\n\n```javascript\nif (test('-d', path)) { /* do something with dir */ };\nif (!test('-f', path)) continue; // skip if it's a regular file\n```\n\nEvaluates expression using the available primaries and returns corresponding value.\n\n### cat(file [, file ...])\n### cat(file_array)\n\nExamples:\n\n```javascript\nvar str = cat('file*.txt');\nvar str = cat('file1', 'file2');\nvar str = cat(['file1', 'file2']); // same as above\n```\n\nReturns a string containing the given file, or a concatenated string\ncontaining the files if more than one file is given (a new line character is\nintroduced between each file). Wildcard `*` accepted.\n\n### 'string'.to(file)\n\nExamples:\n\n```javascript\ncat('input.txt').to('output.txt');\n```\n\nAnalogous to the redirection operator `>` in Unix, but works with JavaScript strings (such as\nthose returned by `cat`, `grep`, etc). _Like 
 Unix redirections, `to()` will overwrite any existing file!_\n\n### sed([options ,] search_regex, replace_str, file)\nAvailable options:\n\n+ `-i`: Replace contents of 'file' in-place. _Note that no backups will be created!_\n\nExamples:\n\n```javascript\nsed('-i', 'PROGRAM_VERSION', 'v0.1.3', 'source.js');\nsed(/.*DELETE_THIS_LINE.*\\n/, '', 'source.js');\n```\n\nReads an input string from `file` and performs a JavaScript `replace()` on the input\nusing the given search regex and replacement string. Returns the new string after replacement.\n\n### grep([options ,] regex_filter, file [, file ...])\n### grep([options ,] regex_filter, file_array)\nAvailable options:\n\n+ `-v`: Inverse the sense of the regex and print the lines not matching the criteria.\n\nExamples:\n\n```javascript\ngrep('-v', 'GLOBAL_VARIABLE', '*.js');\ngrep('GLOBAL_VARIABLE', '*.js');\n```\n\nReads input string from given files and returns a string containing all lines of the\nfile that match the given `regex_filt
 er`. Wildcard `*` accepted.\n\n### which(command)\n\nExamples:\n\n```javascript\nvar nodeExec = which('node');\n```\n\nSearches for `command` in the system's PATH. On Windows looks for `.exe`, `.cmd`, and `.bat` extensions.\nReturns string containing the absolute path to the command.\n\n### echo(string [,string ...])\n\nExamples:\n\n```javascript\necho('hello world');\nvar str = echo('hello world');\n```\n\nPrints string to stdout, and returns string with additional utility methods\nlike `.to()`.\n\n### dirs([options | '+N' | '-N'])\n\nAvailable options:\n\n+ `-c`: Clears the directory stack by deleting all of the elements.\n\nArguments:\n\n+ `+N`: Displays the Nth directory (counting from the left of the list printed by dirs when invoked without options), starting with zero.\n+ `-N`: Displays the Nth directory (counting from the right of the list printed by dirs when invoked without options), starting with zero.\n\nDisplay the list of currently remembered directories. Returns an ar
 ray of paths in the stack, or a single path if +N or -N was specified.\n\nSee also: pushd, popd\n\n### pushd([options,] [dir | '-N' | '+N'])\n\nAvailable options:\n\n+ `-n`: Suppresses the normal change of directory when adding directories to the stack, so that only the stack is manipulated.\n\nArguments:\n\n+ `dir`: Makes the current working directory be the top of the stack, and then executes the equivalent of `cd dir`.\n+ `+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+ `-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.\n\nExamples:\n\n```javascript\n// process.cwd() === '/usr'\npushd('/etc'); // Returns /etc /usr\npushd('+1');   // Returns /usr /etc\n```\n\nSave the current directory on the top of the directory stack and then cd to `dir`. With no arguments, pushd exchanges the t
 op two directories. Returns an array of paths in the stack.\n\n### popd([options,] ['-N' | '+N'])\n\nAvailable options:\n\n+ `-n`: Suppresses the normal change of directory when removing directories from the stack, so that only the stack is manipulated.\n\nArguments:\n\n+ `+N`: Removes the Nth directory (counting from the left of the list printed by dirs), starting with zero.\n+ `-N`: Removes the Nth directory (counting from the right of the list printed by dirs), starting with zero.\n\nExamples:\n\n```javascript\necho(process.cwd()); // '/usr'\npushd('/etc');       // '/etc /usr'\necho(process.cwd()); // '/etc'\npopd();              // '/usr'\necho(process.cwd()); // '/usr'\n```\n\nWhen 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.\n\n### exit(code)\nExits t
 he current process with the given exit code.\n\n### env['VAR_NAME']\nObject containing environment variables (both getter and setter). Shortcut to process.env.\n\n### exec(command [, options] [, callback])\nAvailable options (all `false` by default):\n\n+ `async`: Asynchronous execution. Defaults to true if a callback is provided.\n+ `silent`: Do not echo program output to console.\n\nExamples:\n\n```javascript\nvar version = exec('node --version', {silent:true}).output;\n\nvar child = exec('some_long_running_process', {async:true});\nchild.stdout.on('data', function(data) {\n  /* ... do something with data ... */\n});\n\nexec('some_long_running_process', function(code, output) {\n  console.log('Exit code:', code);\n  console.log('Program output:', output);\n});\n```\n\nExecutes the given `command` _synchronously_, unless otherwise specified.\nWhen in synchronous mode returns the object `{ code:..., output:... }`, containing the program's\n`output` (stdout + stderr)  and its exit `c
 ode`. Otherwise returns the child process object, and\nthe `callback` gets the arguments `(code, output)`.\n\n**Note:** For long-lived processes, it's best to run `exec()` asynchronously as\nthe current synchronous implementation uses a lot of CPU. This should be getting\nfixed soon.\n\n### chmod(octal_mode || octal_string, file)\n### chmod(symbolic_mode, file)\n\nAvailable options:\n\n+ `-v`: output a diagnostic for every file processed\n+ `-c`: like verbose but report only when a change is made\n+ `-R`: change files and directories recursively\n\nExamples:\n\n```javascript\nchmod(755, '/Users/brandon');\nchmod('755', '/Users/brandon'); // same as above \nchmod('u+x', '/Users/brandon');\n```\n\nAlters the permissions of a file or directory by either specifying the\nabsolute permissions in octal form or expressing the changes in symbols.\nThis command tries to mimic the POSIX behavior as much as possible.\nNotable exceptions:\n\n+ In symbolic modes, 'a-r' and '-r' are identical.  No
  consideration is\n  given to the umask.\n+ There is no \"quiet\" option since default behavior is to run silent.\n\n## Configuration\n\n\n### config.silent\nExample:\n\n```javascript\nvar silentState = config.silent; // save old silent state\nconfig.silent = true;\n/* ... */\nconfig.silent = silentState; // restore old silent state\n```\n\nSuppresses all command output if `true`, except for `echo()` calls.\nDefault is `false`.\n\n### config.fatal\nExample:\n\n```javascript\nconfig.fatal = true;\ncp('this_file_does_not_exist', '/dev/null'); // dies here\n/* more commands... */\n```\n\nIf `true` the script will die on errors. Default is `false`.\n\n## Non-Unix commands\n\n\n### tempdir()\nSearches and returns string containing a writeable, platform-dependent temporary directory.\nFollows Python's [tempfile algorithm](http://docs.python.org/library/tempfile.html#tempfile.tempdir).\n\n### error()\nTests if error occurred in the last command. Returns `null` if no error occurred,\notherw
 ise returns string explaining the error\n",
