Newbie "svn update" question

[Mikko Oksalahti <mikko@azila.fi>]

Hi,

I just started using git for my personal projects at home. Basic usage seems 
pretty straight-forward as well as setting up everything. However, I have a 
simple question about how do I mimic an "svn update" command on a locally 
created repository. Here's what I do:

some_existing_project_dir> git init
some_existing_project_dir> git add .

(about 1000 files added...)

some_existing_project_dir> git commit -a -m "initial commit"

(now I edit 10 files and accidentally delete some files that I'm not aware of)

How do I now get the accidentally deleted files back from the repository without 
losing local changes made to 10 files? 

I've tried using: "git checkout HEAD ." but my local changes after last commit 
will be lost.

I've tried using: "git pull ." but the deleted files are not restored.

So I'm looking for an "svn update" equivalent command that would semantically do 
this: "Get the latest version of all files from the repository and merge them 
with any local changes I've made to files."

I know a suitable command is available and I'm just a moron who can't read the 
manual correctly but help me out anyway :P
