Git

Git is software for tracking changes in any set of files, usually used for coordinating work among programmers collaboratively developing source code during software development. Its goals include speed, data integrity, and support for distributed, non-linear workflows.

Installation in Ubuntu

Before the Git installation,update the system.

sudo apt update -y

After completing the updating process,install the Git

sudo apt-get install git

Commands and Operations

Check the version of git

git –version

Firstly, setting up Git

git config –global user.name “safwan”

git config –global user.email “safwanpaloli6@gmail.com”

Initialization Git

git init creates an empty Git repository or re-initializes an existing one. In essence, it creates a .git directory with subdirectories and template files. Running a git init in an existing repository will not overwrite things that are already there. Instead, it picks up the newly added templates.

git init

Create a file, file name is 1.txt

touch 1.txt

Add content to 1.txt using nano editor.

Check the Git status

git status

The files are untracked, so add them to git and commit

Files can differently add to git

A specific file is add to git

git add 1.txt

Add all files to git

git add -A

git add .

git add –all

After the file add and commit a message.

git commit -m “message type here”

Check the log

git log

Add more content on 1.txt file, and add file to git and again to commit file

git log –all

Here see that Commit IDs are unique SHA-1 hashes that are created whenever a new commit is recorded. If you want to push changes to such a repository, you can use the workspace command line to manually commit and push to a new branch.

Create a new branch

Created two branches, One is that feature and design.

git branch feature

git branch design

List the git branches

git branch

See that now branch is pointed to master. Master branch is default branch in git.

Now change to feature branch.

git checkout feature

Again Add some text to 1.txt

Check the different between before commit and after commit.

git diff

The last commit may need to be removed.

git stash

To Delete a local branch.

git branch -d design

Create a Repository in Github

Log in and visit the GitHub homepage to create a new repository on GitHub.

Push a branch to Github

git remote add new_repo https://github.com/safwanpaloli/new_repo.git 

git push new_repo master

Uploading files with a Github password wasn’t possible; we needed to create an access token.

Create a Personal Access Token

Settings-> Developer Settings -> personal access token -> Generate new token

copy the token

Push branch to github

git push new_repo master.

Note : Use Personal access token is the password of git when the push the branch.

Check the git repository.

Successfully branch pushed to github.

Have a Nice Day…
