Question

Now I want to change the application name to be

Answer 1

Run the following to replace the old_name for new_name from the root of your Rails (3.0.7) project.

replace old_name new_name -- ./config/environment.rb ./config/application.rb ./Rakefile ./config/initializers/secret_token.rb ./config/environments/production.rb ./config/environments/development.rb ./app/views/layouts/application.html.erb ./config/routes.rb config.ru ./config/environments/test.rb ./config/initializers/session_store.rb

But be sure to run

fgrep old_name . -iR

Or something similar first to check if there are no occurrences of old_name in your project who not should be replaced.

EDIT:

Of course for this you need to have the replace command installed.

And take in account that your appname will be CamelCased, so maybe you have to try a few different variations, like OldName vs. NewName.
