github - git did not pull my remote file and says Already up-to-date -

I pushed the last version of the project for the guit.

And I would like to make an experiment: I change a file development. RB

And I run git pull I hope my local file development.rb will be replaced by the remote file development.rb. But why is not it?

Not that how git works if you do this:

  git status   
 You will see that you have a pending local change.
