Github usage introduction

Github is a free (if visible to public) internet based software respository and there are lots of open source software on the site. In this blog, we are going to introduce how to use github to push and pull and clone the respository.

create trust relationship between your git client and github.

After you created the github account, you need to add your public key to the github key store.

You need to run the below command as any linux account.

ssh-keygen -t rsa -C “youremail@example.com”

it will then create an .ssh under your home directory. Please don’t change the permission of the directory and files in it.

Then go to you github account and choose “edit your profiles” -> SSH Keys -> Add SSH key

Then choose a title and put your public key (the content of  id_rsa.pub) then save it.

create the remote repository

click the ‘+’ near your account

and give a sound name and discription and probablly choose license type of your repository.

That’s it. Very easy.

link the remote repository with local repository

although usually we will create the remote repository then clone it to the local respository. Sometimes we do it reverse.

Run the below command in your local repository

git remote add origin git@github.com:aaaaatoz/mygit.git

this will link your local repository with the repository called origin (the traditional repository name)

then you can push the content from your local repository to remote repository.

git push -u origin master

it will create the master branch and linked it with your local branch.

Then any modification in your local repository, you can easily push it by

git push origin master

clone the existing repository.

If you have already got a remote repository and want to clone it to the local repository,

There is an easy command:

You can create an empty directory in your Linux box and run:

git clone git@github.com:aaaaatoz/learngit.git

then it will download all the repository stuff to your local box and you can control it easily.

After you modify the content locally you can push it back to github repository by git push origin master
