Pushing your first git repository / project to Github

As we seen in our last two posts “How to create git repository in Github” and “Starting your first Git Repository” we created a local git repository with helloworld.c as source inside that repository, and we also created an empty git repository on github website.

In this post we will push our already existing local git to remote server github.

$ cd git-helloworld/

$ cat .git/config 
[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
	logallrefupdates = true
	editor = vim
[user]
	name = Developer Name
	email = developer@yourcompany.com

Now, we will add the remote repository we created at github to our local git as

$ git remote add origin https://github.com/lynxbee/git-helloworld.git 

$ cat .git/config 
[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
	logallrefupdates = true
	editor = vim
[user]
	name = Developer Name
	email = developer@yourcompany.com
[remote "origin"]
	url = https://github.com/lynxbee/git-helloworld.git
	fetch = +refs/heads/*:refs/remotes/origin/*

As, we can see above, the remote github repository got added to config file with remote name “origin” [ origin is a standard name if cloned remote git, you can use any name if you are adding ]

Now, lets try to push our code to github using below command,

$ git pull origin master --allow-unrelated-histories
From https://github.com/lynxbee/git-helloworld
 * branch            master     > FETCH_HEAD
Merge made by the 'recursive' strategy.
 README.md | 2 ++
 1 file changed, 2 insertions(+)
 create mode 100644 README.md

Note: Refer “Solved : fatal: refusing to merge unrelated histories” to understand why we used –allow-unrelated-histories flag, which otherwise is not required to be used with git pull command.

As we can see above, “git pull” command downloaded remote git contents and merged those to local git, which we can see using “git log”. Below, first and third is the local git commits where as second is from remote server git.

$ git log
commit 4d775269ad1a7906cb51ed84382ad5ce1e6daf3d (HEAD -> master, origin/master)

Author: Developer Name <developer@yourcompany.com>

    This is first commit with helloworld.c

Now, we can push our local git to remote server as,

$ git push origin master
Username for 'https://github.com': YOUR_GITHUB_USERNAME
Password for 'https://YOUR_GITHUB_USERNAME@github.com':

   f96a4d7..4d77526  master > master

We can now see at https://github.com/lynxbee/git-helloworld that we have successfully pushed local code to remote server.
