git fetch and pull

Here, we are migrating our source code to github, and this transaction is giving me headaches :)
what I did: I gone to our workspace (is an eclipse project), and did git init and git add . and then git commit -am "first commit"
everything worked fine, and then, i just pushed it to github. success too.
but there is a big problem: My friend just made a change on a file named A.java and I just changed B.java. ok, not a big deal. then, he pushed it to github. whei I try to push, my push is rejected. Ok, I did a git pull github master and then, push again, and now, my 'commit message' turns like Merge branch 'master' of github.com:germantech/projectName
Ok, what am I doing wrong?
ps: sorry about my english

are you in the same repo or on different repos? If you are you need to rebase your changes and push again

git pull --rebase github master
git push github master

You're not doing anything wrong - when you do git pull github master, git goes to the repository indicated by the remote github, fetches everything needed for the master branch, and then merges it into your current branch. Before the pull, you had the following history:

O --- A (master)

... where O is the commit with the message "firts commit" and A is the commit that introduced your changes to A.java. Your friend, meanwhile, has the history:

O --- B (master)

... and that has been pushed to GitHub. When your git pull github master merges that into your history, it creates a "merge commit" to represent the state of the tree with the changes from both master branches:

O --- B --- M (master)
 \         /
   ---A ---

If, instead, you wanted to keep the history linear, you could do git pull --rebase github master, which would instead would "replay" your commits that aren't in the remote version of the branch on top of that remove version of the branch:

o --- B --- A' (master)

Some people prefer that - I personally don't care.
