Git is a distributed version control system
Git config file
git config --global user.email "email_id"

git add [filename] (or)
git add . [all changed files for commit]
git status (show the status of working tree)
git commit -m "commit message"
git push (push to remote repository)
git pull (fetch changes from remote repository)
git clone [git repo url]
git fetch (fetch branches, tags from remote repository)
Remove files from staging area
git reset file_name (or)
git reset (to remove all files from staging area)
Git Tagging
Git tagging is used to mark an important history like a release v1.0
By default git push will not commit the tags to remote server, instead we have to explicitly mention the remote
git tag -a v1.0 -m "Reason for tagging"
git push origin v1.0
# If there are multiple tags, then use --tags flag
git push origin --tags (to push all tags)
# To list out all the available tags
git tag
git tag -l (or) --list (optional)
Information about Remote Repository
git remote -v
Git branching
# To display all branches that are present remotely and locally
git branch -a
# To create a new branch
git branch branch_name
git checkout branch_name
Discard all local changes
# discard all local changes/commits and pull from upstream
git reset --hard origin/master
git pull origin master
Commit History
To check commit history : git log
Revert commits
git revert <commit-id>
