I'm learning ruby from Patrick Lenz's "Build your Ruby On Rails Applications". Please help me with the following -

I'm trying to do the following (copy-paste from book)

To enter a Rails console, change to your shovell folder, and enter the command
ruby script/console, as shown below. The >> prompt is ready to accept your
$ cd shovell
$ ruby script/console
Loading development environment.
Please answer -

1. Where exactly is 'shovell' folder located?
2. I'm getting "ruby - no such file or directory -- script/console (LoadError)

What am I doing wrong?
