undoing changes with git-checkout -f

[lamikr <lamikr@cc.jyu.fi>]

Hi

Can somebody tell have I understood git-checkout -f wrong as following
does not work as I thought
1) I clone git repo by using command

    git-clone rsync://source.mvista.com/git/linux-omap-2.6.git
linux-omap-2.6

2) I go to cloned repo and create there a new file
    cd linux-omap-2.6
    echo "test" > 1.txt

3) I want to undo the creation of 1.txt by using command
    git-checkout -f

but for some reason the 1.txt is still displayed in the root of
linux-omap-2.6 directory. (I have also tried "git-reset --hard" but
seems to have same effect)
What am I doing wrong?
