Display terminal output on web browser?

Here is my case:

I want to use a web browser to connect to a Rails application that runs this example c开发者_StackOverflowode on the server side:

Dir.chdir path_typed_in_by_user
system "ls -la"

I want the output of "ls -la" to be displayed on the web browser.

Is this possible somehow?
