Getting started:

https://tutorialzine.com/2016/06/learn-git-in-30-minutes

1. Installing Git

sudo apt-get install git

2. Configuring Git

$ git config --global user.name "My Name"

3. Creating a new repository - git init

$ cd Desktop/git_exercise/

4. Checking the status - git status

$ git status

5. Staging

$ git add hello.txt

or

$ git add -A

equivalent to

$ git add .

6. Commiting

$ git commit -m "Initial commit."

7. Modify the last commit message:

$ git --amend

Start your Git repo anew

To remove the git file and create anew in the repo:

cd /path/to/your/repo
rm -rf .git
git init

Add a remote repository

In general:

$ git remote add origin https://github.com/tutorialzine/awesome-project.git

Push to remote:

If it’s a commit on the master branch:

$ git push origin master

If it’s a commit on some branch named “some-branch”:

$ git push origin some-branch

Pull request

In our workflow we shall send code to CR (code review) before it goes to QA.

Create a branch

For that you create a branch, then push the code to your branch and the pull request is done in the master branch dashboard.

$ git branch some-feature 
$ git checkout some-feature

You can create the branch and go in the branch in command:

$ git checkout -b some-feature

# Edit some code

$ git commit -a -m "Add first draft of some feature"

$ git push origin some-branch

“After Bitbucket has her feature branch, Mary can create the pull request through her Bitbucket account by navigating to her forked repository and” clicking on Pull requests in the side bar and then “clicking the Pull request button in the top-right corner.“

Set gitignore

https://www.atlassian.com/git/tutorials/saving-changes/gitignore

https://git-scm.com/docs/gitignore

touch ~/.gitignore

git config --global core.excludesFile ~/.gitignore

sudo vim ~/.gitignore

edit file with:

*.css.map

to exclude all files ending with .css.map

for a local approach simply create and edit the .gitignore file in the affected local repository.

If the file has already been staged, remove it by using:

$ git restore --staged <file>.

All those worked:

/source

*/.sass-cache

*/codeStyles

.gitignore

the directory tree was:

|

|-source

|-.sass-cache

|-.idea

|-codeStyles

If you accidentally sync and can’t push anymore:

hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

create a force push:

git push -f origin branchname

Set git Locally

https://docs.github.com/en/github/getting-started-with-github/setting-your-username-in-git

cd in the folder were you want to clone the repo:

$ cd directory/you/clone

$ git init

$ git config user.name “Your-Username” #can be different from your github username

$ git config user.email “your.email@example.com”

$ ssh-keygen -t rsa -C “your.email@example.com”

Enter file in which to save the key (/home/username/.ssh/id_rsa): /home/username.ssh/id_rsa

copy the content of the id_rsa.pub in your github settings in your profile.

Set github local authentication to be able to clone and push:
