how to get a list of all the switches for: rails new

I want to learn all the possible options when doing:

rails new

Is there a way to output them?


Just type:

$ rails new --help


rails new APP_PATH [options]


-r, [–ruby=PATH] # Path to the Ruby binary of your choice

Default: /home/everaldo/.rvm/rubies/ruby-1.9.2-p290/bin/ruby

-b, [–builder=BUILDER] # Path to a application builder (can be a filesystem path or URL)

-m, [–template=TEMPLATE] # Path to an application template (can be a filesystem path or URL)

[–skip-gemfile] # Don’t create a Gemfile

[–skip-bundle] # Don’t run bundle install

-G, [–skip-git] # Skip Git ignores and keeps

-O, [–skip-active-record] # Skip Active Record files

-S, [–skip-sprockets] # Skip Sprockets files

-d, [–database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db/sqlserver/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc)

Default: sqlite3

-j, [–javascript=JAVASCRIPT] # Preconfigure for selected JavaScript library

Default: jquery

[–edge] # Setup the application with Gemfile pointing to Rails repository

[–old-style-hash] # Force using old style hash (:foo => ‘bar’) on Ruby >= 1.9

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:

-h, [–help] # Show this help message and quit

-v, [–version] # Show Rails version number and quit


The ‘rails new’ command creates a new Rails application with a default

directory structure and configuration at the path you specify.


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.
