git add .

Add all the files in the current folder to the staging area.

git commit -m COMMIT_MESSAGE

Commit the changes to the Git repository.

git push -u origin master

Push the contents of the local repository to the origin to the master branch.

git log --oneline

See the commit history in a Git repository in a single line.

You added some code in the file but you want to revert back to the state of the file before you added the code. (You have not staged the file yet.)

Git Branches

git checkout -b BRANCH_NAME

Create a branch.

git branch -a

To view both remote tracking branches and local branches.

git checkout BRANCH_NAME

To checkout an existing branch.

Generally, Git won’t let you checkout another branch unless your working directory is clean, because you would lose any working directory changes that are not committed.

git branch m OLD_BRANCH_NAME NEW_BRANCH_NAME

Rename a branch.

git branch -d BRANCH_TO_DELETE

Delete a branch.

Git won’t let you delete a branch that you are currently on. You first need to checkout a different branch and then run the command.

git branch -D BRANCH_TO_DELETE

Git will throw an error if the changes in the branch you are trying to delete are not fully merged into the current branch. You can override this and force Git to delete the branch with the -D option (‘D’ is in capital).

git push -u origin BRANCH_NAME

Push your branch to the remote repository.

git push origin --delete BRANCH_TO_DELETE

Delete a branch remotely.

git checkout master

Checkout to master branch.

git merge BRANCH_NAME

Merges the specified branch into the currently active branch.
