title: How to run "rails s"
body: <p>I have a problem running <code>rails s</code> in Ubuntu. When I type <code>rails s</code> it doesn't start the server, but instead it outputs:</p>
  <pre><code>kyala@ubuntu:~/depot$ rails s
  
  Usage:
    rails new APP_PATH [options]
  
  Options:
    
  -r, [--ruby=PATH]           # Path to the Ruby binary of your choice
                                # Default: /home/kyala/.rvm/rubies/ruby-1.9.2-p290/bin/ruby
    
  -d, [--database=DATABASE]   # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db)enter code here
                                # Default: sqlite3
   
   -b, [--builder=BUILDER]     # Path to an application builder (can be a filesystem path or URL)
    
  -m, [--template=TEMPLATE]   # Path to an application template (can be a filesystem path or URL)
        [--dev]                 # Setup the application with Gemfile pointing to your Rails 
  
  checkout
        [--edge]                # Setup the application with Gemfile pointing to Rails 
  
  repository
        
  [--skip-gemfile]        # Don't create a Gemfile
   
   -O, [--skip-active-record]  # Skip Active Record files
   
   -T, [--skip-test-unit]      # Skip Test::Unit files
   
   -J, [--skip-prototype]      # Skip Prototype files
   
   -G, [--skip-git]            # Skip Git ignores and keeps
  
  
  Runtime options:
   
  -f, [--force]    # Overwrite files that already exist
    
  -p, [--pretend]  # Run but do not make any changes
   
   -q, [--quiet]    # Supress status output
   
   -s, [--skip]     # Skip files that already exist
  
  
  Rails options:
   
   -v, [--version]  # Show Rails version number and quit
  
    -h, [--help]     # Show this help message and quit
  
  
  Description:
    
    The 'rails new' command creates a new Rails application with a default
     
   directory structure and configuration at the path you specify.
  
  Example:
    
    rails new ~/Code/Ruby/weblog
  
     
   This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
      
  See the README in the newly created application to get going.
