Version control systems like Git are tools used to track changes to source code (or other collections of files and folders). As the name implies, these tools help maintain a history of changes; furthermore, they facilitate collaboration. Source : Missing-Semester/Git


$ git init

$ git add .

$ git checkout -- .

$ git commit -m "First Commit"

$ git commit --amend -m "An updated commit message"

$ git status

$ git log

$ git log --all --graph --decorate

$ git checkout <commit-id>

$ git checkout -b <branch>

$ git diff

$ git merge <branch-name>

$ git reflog

$ git reset HEAD@{<id>}

$ git reset --hard HEAD~<number-of-commits-to-undo>

$ git push origin HEAD -f


In case of merge conflict, resolve conflict manually / using VSCode / other tools.
