The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('commander');\n\nprogram\n  .version('0.0.1')\n  .option('-p, --peppers', 'Add peppers')\n  .option('-P, --pineapple', 'Add pineapple')\n  .option('-b, --bbq', 'Add bbq sauce')\n  .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')\n  .parse(process.argv);\n\nconsole.log('you ordered a pizza with:');\nif (program.peppers) console.log('  - peppers');\nif (program.pineapple) console.log('  - pineapple');\nif (program.bbq) console.log('  - bbq');\nconsole.log('  - %s cheese', program.cheese);\n```\n\n Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as \"--template-engine\" are camel-cased, becoming `program.templateEngine` etc.\n\n\n## Coercion\n\n```js\nfunction range(val) {\n  return val.split('..').map(Number);\n}\n\nfunction list(val) {\n  return val.split(',');\n}\n\nfunction collect(val, memo) {\n  memo.push(val);\n  return memo;\n}\n\nfunction increaseVerbosity(v, total) {\n  return total + 1;\n}\n\nprogram\n  .version('0.0.1')\n  .usage('[options] <file ...>')\n  .option('-i, --integer <n>', 'An integer argument', parseInt)\n  .option('-f, --float <n>', 'A float argument', parseFloat)\n  .option('-r, --range <a>..<b>', 'A range', range)\n  .option('-l, --list <items>', 'A list', list)\n  .option('-o, --optional [value]', 'An optional value')\n  .option('-c, --collect [value]', 'A repeatable value', collect, [])\n  .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)\n  .parse(process.argv);\n\nconsole.log(' int: %j', program.integer);\nconsole.log(' float: %j', program.float);\nconsole.log(' optional: %j', program.optional);\nprogram.range = program.range || [];\nconsole.log(' range: %j..%j', program.range[0], program.range[1]);\nconsole.log(' list: %j', program.list);\nconsole.log(' collect: %j', program.collect);\nconsole.log(' verbosity: %j', program.verbose);\nconsole.log(' args: %j', program.args);\n```\n\n## Variadic arguments\n\n The last argument of a command can be variadic, and only the last argument.  To make an argument variadic you have to\n append `...` to the argument name.  Here is an example:\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('commander');\n\nprogram\n  .version('0.0.1')\n  .command('rmdir <dir> [otherDirs...]')\n  .action(function (dir, otherDirs) {\n    console.log('rmdir %s', dir);\n    if (otherDirs) {\n      otherDirs.forEach(function (oDir) {\n        console.log('rmdir %s', oDir);\n      });\n    }\n  });\n\nprogram.parse(process.argv);\n```\n\n An `Array` is used for the value of a variadic argument.  This applies to `program.args` as well as the argument passed\n to your action as demonstrated above.\n\n## Git-style sub-commands\n\n```js\n// file: ./examples/pm\nvar program = require('..');\n\nprogram\n  .version('0.0.1')\n  .command('install [name]', 'install one or more packages')\n  .command('search [query]', 'search with optional query')\n  .command('list', 'list packages installed')\n  .parse(process.argv);\n```\n\nWhen `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.  \nThe commander will try to find the executable script in __current directory__ with the name `scriptBasename-subcommand`, like `pm-install`, `pm-search`.\n\n## Automated --help\n\n The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:\n\n```  \n $ ./examples/pizza --help\n\n   Usage: pizza [options]\n\n   An application for pizzas ordering\n\n   Options:\n\n     -h, --help           output usage information\n     -V, --version        output the version number\n     -p, --peppers        Add peppers\n     -P, --pineapple      Add pineapple\n     -b, --bbq            Add bbq sauce\n     -c, --cheese <type>  Add the specified type of cheese [marble]\n     -C, --no-cheese      You do not want any cheese\n\n```\n\n## Custom help\n\n You can display arbitrary `-h, --help` information\n by listening for \"--help\". Commander will automatically\n exit once you are done so that the remainder of your program\n does not execute causing undesired behaviours, for example\n in the following executable \"stuff\" will not output when\n `--help` is used.\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('commander');\n\nprogram\n  .version('0.0.1')\n  .option('-f, --foo', 'enable some foo')\n  .option('-b, --bar', 'enable some bar')\n  .option('-B, --baz', 'enable some baz');\n\n// must be before .parse() since\n// node's emit() is immediate\n\nprogram.on('--help', function(){\n  console.log('  Examples:');\n  console.log('');\n  console.log('    $ custom-help --help');\n  console.log('    $ custom-help -h');\n  console.log('');\n});\n\nprogram.parse(process.argv);\n\nconsole.log('stuff');\n```\n\nYields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:\n\n```\n\nUsage: custom-help [options]\n\nOptions:\n\n  -h, --help     output usage information\n  -V, --version  output the version number\n  -f, --foo      enable some foo\n  -b, --bar      enable some bar\n  -B, --baz      enable some baz\n\nExamples:\n\n  $ custom-help --help\n  $ custom-help -h\n\n```\n\n## .outputHelp()\n\n  Output help information without exiting.\n\n## .help()\n\n  Output help information and exit immediately.\n\n## Examples\n\n```js\nvar program = require('commander');\n\nprogram\n  .version('0.0.1')\n  .option('-C, --chdir <path>', 'change the working directory')\n  .option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')\n  .option('-T, --no-tests', 'ignore test hook')\n\nprogram\n  .command('setup [env]')\n  .description('run setup commands for all envs')\n  .option(\"-s, --setup_mode [mode]\", \"Which setup mode to use\")\n  .action(function(env, options){\n    var mode = options.setup_mode || \"normal\";\n    env = env || 'all';\n    console.log('setup for %s env(s) with %s mode', env, mode);\n  });\n\nprogram\n  .command('exec <cmd>')\n  .alias('ex')\n  .description('execute the given remote cmd')\n  .option(\"-e, --exec_mode <mode>\", \"Which exec mode to use\")\n  .action(function(cmd, options){\n    console.log('exec \"%s\" using %s mode', cmd, options.exec_mode);\n  }).on('--help', function() {\n    console.log('  Examples:');\n    console.log();\n    console.log('    $ deploy exec sequential');\n    console.log('    $ deploy exec async');\n    console.log();\n  });\n\nprogram\n  .command('*')\n  .action(function(env){\n    console.log('deploying \"%s\"', env);\n  });\n\nprogram.parse(process.argv);\n```\n\nYou can see more Demos in the [examples](https://github.com/tj/commander.js/tree/master/examples) directory.\n\n## License\n\n(The MIT License)\n\nCopyright (c) 2011 TJ Holowaychuk &lt;tj@vision-media.ca&gt;\n\nPermission is hereby granted, free of charge, to any person obtaining\na copy of this software and associated documentation files (the\n'Software'), to deal in the Software without restriction, including\nwithout limitation the rights to use, copy, modify, merge, publish,\ndistribute, sublicense, and/or sell copies of the Software, and to\npermit persons to whom the Software is furnished to do so, subject to\nthe following conditions:\n\nThe above copyright notice and this permission notice shall be\nincluded in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND,\nEXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF\nMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.\nIN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY\nCLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT,\nTORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE\nSOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.\n",
