git repository sync between computers, when moving around?

Question

Let's say that I have a desktop pc and a laptop, and sometimes I work on the desktop and sometimes I work on the laptop.

What is the easiest way to move a git repository back and forth?

I want the git repositories to be identical, so that I can continue where I left of at the other computer.

I would like to make sure that I have the same branches and tags on both of the computers.

Thanks Johan

Note: I know how to do this with SubVersion, but I'm curious on how this would work with git. If it is easier, I can use a third pc as classical server that the two pc:s can sync against.

Note: Both computers are running Linux.

Update:

So let's try XANI:s idea with a bare git repo on a server, and the push command syntax from KingCrunch. In this example there is two clients and one server.

So let's create the server part first.

ssh user@server mkdir -p ~/git_test/workspace cd ~/git_test/workspace git --bare init 

So then from one of the other computers I try to get a copy of the repo with clone:

git clone user@server:~/git_test/workspace/ Initialized empty Git repository in /home/user/git_test/repo1/workspace/.git/ warning: You appear to have cloned an empty repository. 

Then go into that repo and add a file:

cd workspace/ echo "test1" > testfile1.txt git add testfile1.txt git commit testfile1.txt -m "Added file testfile1.txt" git push origin master 

Now the server is updated with testfile1.txt.

Anyway, let's see if we can get this file from the other computer.

mkdir -p ~/git_test/repo2 cd ~/git_test/repo2 git clone user@server:~/git_test/workspace/ cd workspace/ git pull 

And now we can see the testfile.

At this point we can edit it with some more content and update the server again.

echo "test2" >> testfile1.txt git add testfile1.txt git commit -m "Test2" git push origin master 

Then we go back to the first client and do a git pull to see the updated file. And now I can move back and forth between the two computers, and add a third if I like to.

I think, there are multiple approaches. I will just describe, how I handle this

I have one netbook as a 24/7 server, that holds multiple git-repositories. From/To there I push and pull changes via SSH. For access from outside I use dyndns.org. It works fine, especially because I have more than two systems, that needs access to some of the repositories.

Update: A little example. Lets say my netbook is called "netbook". I create a repository there

$ ssh [email protected] $ cd ~/git $ mkdir newThing $ cd newThing $ git init --bare 

On my desktop I will than create a clone of it. Maybe I will add some files also

$ git clone [email protected]:/home/username/git/newThing $ git add . $ git commit -m "Initial" $ git push origin master 

On my portables I will (first) do the same, but for remote access (from outside my LAN), I will also add the external address.

$ git clone [email protected]:/home/username/git/newThing $ git remote add externalName [email protected]:/home/username/git/newThing $ git pull externalName master 

Its just the way git (/git workflows) works. You can add as many remote repositories as you like. It doesnt matters, if two or more refers to the same "physical" repositories. You dont need an own local "server", you can use any public server, to which you have ssh access. And of course you dont need a public server at all, if you dont need access from outside. The bare repository can also be on the desktop system and you can then create a working-copy-repository within the local filesystem.

$ mkdir myRepo; cd myRepo $ git init --bare $ cd /path/to/myProject $ git remote add origin /path/to/myRepo $ git add .; git commit -m "Initial"; git push origin master 

This is the way, how I handle this, and I for me it works quite fine (if not perfect ;))
