no gitignore file in app after the "rails new app" command


Im following this tutorial,

but when trying to get pass 1.3.1 part im having trouble figuring out
why I can't see the gitignore file in my rails directory.

this what happens when I entered "gem list".

I (think) have everything installed.

eyal@eyal-laptop:~/rails_projects/ap$ gem list

and this what happens when I create a new rails application, and hit ls

Thanks in advance..

.gitignore is a hidden file (it has a leading dot). To see it type
ls -a
or if you are using graphic file manager you can show hidden files.
In Nautilus this is ctrl h
