Simple problem

I ran into an issue earlier today that I didn't know how to easily solve in git. I'm sure it is easy to handle, but I wasn't sure how.

I removed a file and then realized I'd hit the wrong one. So all I wanted to do was to get the file back the way it was in the last commit.

Basically I wanted something similar to:

svn update myfile

in subversion.  

I got it back by using a diff and just deleting all the minus signs at the beginning of the lines, but I'm sure this isn't the way to handle this. Strangely this simple case wasn't covered by any of the tutorials I looked at.

Thanks.
