Project on GIT / GIT-HUB : Tutorial🚀

GIT : Global Information Tracker

git is a type of file system which has version control feature

git has version id or hash id by this we can roll-back our deleted file.

Types >

VCS : Version control system

DVCS > Distributed Version control system

CVCS > centralized Version control system

TO enable version control

CMD > sudo dnf install git -y

CMD > git init

when we use CMD > ls -al .git hidden folder will get visible

To get file untracked to stage we use CMD > git add i.e git add nibba.txt

To restore file from git CMD > git restore commands.txt

For unstage we use CMD > git restore --staged commands.txt

For commit we use CMD > git commit

git commit -m "feat: nibba nibbi added to repo/relationship"

git commit -m "fix: added newer commands"

To see which file we have commited CMD > git status

ls git add himani.txt git commit -m "feat: nihal added to repo/papa" git log

how to restore file by version control id

To define author who have added the file in git version control git config --global user.name "NIHALPAPA" git config --global user.email "papanihal360@gmail.com"

when you add a file in versioning control can observe your name in author i.e commit 5a5ce7f687061b437c2417aa9d5650c0855571 (HEAD -> master) Author: NIHALPAPA papanihal360@gmail.com Date: Tue Feb 20 07:10:53 2024 +0000

feat: commands.txt version 3 file system

Branch concept Main branch name is Master

to check the branch name CMD > git branch

for a safer side we will use new branch for our project CMD > git checkout -b dev (this will show switch to a new branch)

-b stands for create a new branch

switch between branches git checkout master

touch dev.txt git add dev.txt git commit -m "feat: added dev file"

For getting git hub file in local machine or ec2 instance git by pasting below command by git account repository link git clone https://github.com/NIHALPAPA/my-first-terraform-project.git

Pull file from origin or github repository

pull from Remote machine CMD > git pull origin main

pushing file to Remote machine we are giving developer access to our github repository

setting to do in github account where our main repo is store so we can push our file to main repo Account setting > developer setting > personal access token (classic) > Generate a personal access token

To execute this CMD we have to be in the directory which has been clone from Git-Hub Account pushing file to Remote machine

1. Check for Existing Remote > git remote -v

git remote -v we will get after this CMD

origin https://github.com/NIHALPAPA/my-first-terraform-project.git (fetch) origin https://github.com/NIHALPAPA/my-first-terraform-project.git (push)

2. Add Remote Before Setting URL > git remote add origin https://Access-Token@github.com/NIHALPAPA/devops-batch-6.git

3. Set URL for Existing Remote "origin" > git remote set-url origin https://Access-Token@github.com/NIHALPAPA/devops-batch-6.git

4. Check for Existing Remote > git remote -v

Operate through ssh for github git clone sshlink

CMD > git clone git@github.com:NIHALPAPA/my-first-terraform-project.git there will be denied in ssh key

ssh-keygen add a new public key to SSH Keys in github account

GIT_SSH_COMMAND="ssh -i /home/ubuntu/.ssh/github_key" git clone git@github.com:NIHALPAPA/my-first-terraform-project.git

To save local changes in git CMD > git stash

To check what changes and made in a file CMD > git diff

How to revert the commit copy the commit id which you want to revert

git revert commit-id

i.e git revert fda3cf3

Never use this CMD this will terminate furthur files of git log

CMD > git reset d92d3f8 (use in only emergency)

New concept > Merge/ Rebase

For safer side switch to base branch i.e Master

CMD > git switch master

CMD > git merge dev (this command transfer the HEAD to master to default branch of git)

New concept > Rebase

Rebase is use for proper alligning of the commits in a series according to their upload

CMD > git rebase master

New concept > code and files transfer to github from ec2 instance CMD > git remote add origin https://github.com/NIHALPAPA/devops-batch-6.git CMD > git remote -v This will display after this cmd origin https://github.com/NIHALPAPA/devops-batch-6.git (fetch) origin https://github.com/NIHALPAPA/devops-batch-6.git (push)

setting to do in github account where our main repo is store so we can push our file to main repo Account setting > developer setting > personal access token (classic) > Generate a personal access token

CMD > git status -1:41:50

make repository in github (repo name should be same in github as well as ec2 instance) i.e > devops-batch-6

CMD > git remote -v (to check rather remote exist or not)

CMD > git remote add origin https://github.com/NIHALPAPA/devops-batch-6.git

CMD > git remote -v

CMD > git remote set-url origin https://Access-Token@github.com/NIHALPAPA/devops-batch-6.git

CMD > git push origin master

CMD > git pull origin master

New concept > Branch protection rule for Github

select a branch > go to its setting > branches > add branch protection rules

add branch name in > branch name pattern

select options > Require a pull request before merging Require approval

New concept > When branch is not visible in EC-2 machine CMD > git branch CMD > git pull origin staging CMD > git checkout staging CMD > git branch

To fetch all the branches CMD > git fetch --all
