Pushing changes to origin master

Once you commit a revision to your local repository, you will need to push it up to origin/master (e.g. trunk in SVN terms). This tutorial will cover a simple push where you are synced up with origin/master and one where you are not and you need to pull in changes (step 4).

1. Let's say we left off from the Committing changes tutorial:

   % git commit -m "Adding clean instructions to INSTALL"
   [master 8e89ada] Adding clean instructions to INSTALL
    1 files changed, 4 insertions(+), 0 deletions(-)
   % git status
   # On branch master
   # Your branch is ahead of 'origin/master' by 1 commit.
   #
   # Changed but not updated:
   #   (use "git add <file>..." to update what will be committed)
   #   (use "git checkout -- <file>..." to discard changes in working
   #   directory)
   #
   #  modified:   INSTALL
   #  modified:   README
   #
   no changes added to commit (use "git add" and/or "git commit -a")
   

2. Now run git push origin master (subsequent pushes can omit the origin master arguments).

   % git push
   Counting objects: 5, done.
   Delta compression using up to 2 threads.
   Compressing objects: 100% (3/3), done.
   Writing objects: 100% (3/3), 408 bytes, done.
   Total 3 (delta 0), reused 0 (delta 0)
   To git@github.com:abhikp/git-test.git
       e055ef5..8e89ada  master -> master
   

3. You can confirm that you and origin are synced up by running git status again.

   % git status
   # On branch master
   # Changed but not updated:
   #   (use "git add <file>..." to update what will be committed)
   #   (use "git checkout -- <file>..." to discard changes in working
   #   directory)
   #
   #    modified:   INSTALL
   #    modified:   README
   #
   no changes added to commit (use "git add" and/or "git commit -a")
   

4. If your revision list (disregarding the last commit) doesn't match that of origin master it will complain when you run git push.

   % git push
   To git@github.com:abhikp/git-test.git
   ! [rejected]        master -> master (non-fast-forward)
   error: failed to push some refs to 'git@github.com:abhikp/git-test.git'
   To prevent you from losing history, non-fast-forward updates were rejected
   Merge the remote changes before pushing again.  See the 'Note about
   fast-forwards' section of 'git push --help' for details.
   

5. You'll need to sync back up by pulling from origin master. We'll just run the commands here and leave the details to Pulling from a remote branch.

   % git stash

   HEAD is now at f35474c Adding clean instructions to INSTALL
   % git pull --rebase
