If you only want to read the whole file, you can use this method:

@file_content = File.read(fileName);

You can assign the file's content to a instance variable (prefixed with an @) and show it in your view (*.html.erb or *.erb):

File content: <%= @file_content %>

Additionally, if you call redirect then your view won't be rendered and the user will be redirected to the specified action (index). So the code for the controller action should be this:

def text
  @file_content = File.read(fileName);
  render action: 'text'
end
