git push- Sends changes from a local branch to a remote repository.git fetch- Gets changes from a remote repository into your tracking branch.git pull- Gets changes from a remote branch into your tracking branch and merges them into a local branch.
Both git push and git fetch first check whether your current branch is connected to a tracking branch for a remote repository before proceeding. A git push fails if the remote branch diverges from your local branch. Synchronize your local and remote branch via git pull or git fetch and git merge to resolve the issue.
git fetch allows you to review changes before merging branches. git fetch only changes your local branch when you use git merge. For example, git merge origin/master merges changes into your local branch called "master." git fetch and git pull are often described as equivalent. However, git pull performs a git fetch then a git merge.
