What is `git push` used for?

git push is used to send local commits to a remote repository.

When you run git push:

• local commits are transferred to the server
• the corresponding branch in the remote repository is updated
• changes become available to other developers
• the remote repository is synced with the local one

Important:

• git push sends only commits, not just files
• if no commits were created (git commit), there is nothing to send
• a push is only possible if the local history is compatible with the remote one (otherwise Git requires running fetch/pull first)

git push is usually used for:

• publishing your work
• sharing changes with the team
• updating remote branches
• triggering CI/CD and code review processes

In short: git push publishes local changes to the remote repository.
