What is the difference between git push and git pull, and what is each used for?

git push is used to send local changes (commits) to a remote repository. It updates the remote repository to match the local state. Roughly speaking, you are sharing your work.

git pull is used to fetch changes from a remote repository and integrate them into the current local branch. It is equivalent to running git fetch followed by git merge. It synchronizes your local repository with the remote.

The difference in data flow direction: push sends changes from local to remote, while pull receives changes from remote to local.

Example of using git push:

# Send changes to the main branch on origin
git push origin main 

Example of using git pull:

# Fetch changes from the main branch on origin
git pull origin main
