For adding all files in one
git add .
commit - It is the record of chnage
git commit -m "some massage"
here m for massage
push - Upload local repo (folder/file) to remote repo
git push origin main
,here main is branch

A[Untracked] --> B[Add]
B --> C[Commit]
C --> D[Push]
Init - used to create a new git repo
When we make a new folder then you have initilise it first.
git init
git remote add origin <link>
git remote -v (to verify remote)
git branch(to check branch)
git branch -M main(to rename branch)
git push origin main
git push -u origin main
here, u mean upstream you dont need to say again n again origin main.
so from the next time just use
git push
flowchart TB
A[Create new repository in Github] --> B[Create folder in local machine and open with VS code ]
B --> C[git init]
C --> D[git remote add origin .... ]
D --> E[ git add .]
E --> F[git commit -m ....]
F --> G[git push origin main]
git branch (to check branch)
git branch -M main (to renmae branch)
git checkout < branch name > (to navigate)
git checkout -b <new branch name > (to create new branch)
git branch -d <branch name > (to delete branch)
git diff < branch name > (to compare , commits ,branches , files and more)
git merge <Branch name > (to merge 2 branches)
to Create a pull request
Pull request - It tells you others about chnges you 've pushed to a branch in a repositoey on Github.
git pull origin main
used to detch and download content from a remote repo and immediately update the local repo to match that content.
An event that takes place when git is unable to automatically resolve differences in code between two commits.
git reset <-file name->
git reset
git rese HEAD~1 => HEAD 1 is our latest commit
git reset<-commit hash-> => To reset more commit
git reset --hard <-commit hash-> => Chnage in VS code too
To see all commit use
git log
and q for quit
A fork is a new repository that shares code and visibility settings with the originak "upstream repository"
Fork is rough copy
