How to create a git repo

Create repo

The first things you have to do is create an account on github

Now follow this sequence:

  • Create a repo online on your new account
  • Create a folder in your pc that will contains all the materials of the repo

I suggest you to name it as your repo mkdir <reponame>

  • echo "# <reponame>" >> README.md
  • git init
  • git add README.md
  • git commit -m "first commit"
  • git remote add origin https://gitlab.com/<username>/<reponame>.git
  • git push -u origin master

You'll be asked to insert your username and password.

Now you should have all up and running.

From now on is all up to you, just put files into your folder or create hardlink to file that you already have ln [target] [file name].

Add files

You can add file in three ways:

  • git add [filename] will simply add [filename]
  • git add . will add all modified file
  • git add -i will launch an interactive prompt to add file

Commit files

After you add a file you must always commit it.

Commit a file means adding a very short description to the changes you have made (two or three word, like fixed that or added that, you can write everything you want and everyone can read it).

Push files

Nothing will be displayed on your repo untile you push them.

For doing it you have to run git push -u origin master inside the folder in your computer.

Using SSH instead of HTTPS

Create SSH key

  • ssh-keygen -t rsa -b 4096 -C "[email protected]"
  • eval "$(ssh-agent -s)"
  • ssh-add ~/path/to/file

Follow this link to create an SSH key to use with gitlab.

set ssh on repo

  1. Go to the folder you wish to change in your local PC.
  2. git remote -v to get the remote name of what you want to change
    • This should be your output:
    • origin https://gitlab.com/USERNAME/REPOSITORY.git (fetch)
    • origin https://gitlab.com/USERNAME/REPOSITORY.git (push)
  3. git remote set-url origin [email protected]:USERNAME/REPOSITORY.git
  4. git remote -v again to see if it worked

If you protect your key with a password, you will only be asked for that, otherwise you don't need to input anything to push.

switching to gitLab

Follow the instruction here

In your local folder run: git remote set-url origin origin [email protected]:<username>/<reponame>.git

Configuration of git and ssh for multiple account

Source here.

  • cd ~/.ssh
  • vim config
    1. Account 1
        # account_1
    Host gitlab.com
    HostName gitlab.com
    User git
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_account_1
    1. Account 2
        # Account2
    Host bitbucket.org
    HostName bitbucket.org
    User git
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_account2
    1. Account 3
        # Account_3
    Host github.com
    HostName github.com
    User git
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_account_3

If you set the Host above equal to the HostName than you are all set up, otherwise you need to add remote url as follows:

  1. Account 1 
    git remote add origin [email protected]_1:group_name/repo_name.git
  2. Account 2 
    git remote add origin [email protected]:group_name/repo_name.git
  3. Account 3 
    git remote add origin github.com-Account3:github_username/repo_name.git
