In the following post I will demonstrate how to update my github files :
so , lets init :
git config --global user.email "yanivaws@gmail.com" git config --global user.name "yapale" git config --global credential.helper cache --timeout=3600 git remote add origin https://github.com/yapale/puppet_modules.git git clone https://github.com/yapale/puppet_modules.git cd puppet_modules/ git status #Just to ensure that nothing is running
# On branch master
# Changes not staged for commit:
# (use “git add …” to update what will be committed)
# (use “git checkout — …” to discard changes in working directory)
#
# modified: yapale-vim/manifests/init.pp
#
no changes added to commit (use “git add” and/or “git commit -a”)
git add yapale-vim/manifests/init.pp git status
# On branch master
# Changes to be committed:
# (use “git reset HEAD …” to unstage)
#
# modified: yapale-vim/manifests/init.pp
#
git commit -m "update for home dir" git status
# On branch master
# Your branch is ahead of ‘origin/master’ by 1 commit.
# (use “git push” to publish your local commits)
#
#nothing to commit, working directory clean
git push -u origin master git status
# On branch master
# nothing to commit, working directory clean
