You can specify extra command-line arguments to be used every time 'rails new' runs in the .railsrc configuration file in your home directory, or in $XDG_CONFIG_HOME/rails/railsrc if XDG_CONFIG_HOME is set. Note that the arguments specified in the .railsrc file don't affect the defaults values shown above in this help message. Example: rails new ~/Code/Ruby/weblog This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
