remote repositories.

6. GIT OPERATIONS
git checkout [branch name] - Switch to specified branch
git pull origin [branch name] - fetch the latest changes to the working directory
git checkout –b [branch name] - create a new branch and switched to that
git status - shows the status of operation
git add [./folder/file] - It will add the files to staging
git push origin [branch name] - It will push the changes to the remote repository
git reset HEAD [file] - to unstage or undoing

7. git merge -It will merge the changes from other branch to current branch
git log -It will show the logs with commit code
git revert [commit code] - It will undo the changes
git stash - It saves your local modifications away and reverts the working
directory to match the HEAD commit.
git branch –D branch_name - for deleting a branch

8. WEBHOOKS
Webhooks allow you to
build or set up integrations,
such as GitHub Apps or
OAuth Apps, which
subscribe to certain events
on GitHub.com.
Webhooks can be used to
update an external issue
tracker, trigger CI builds,
update a backup mirror, or
even deploy to your
production server.
