The difference between git pull and git push

There are 2 commands in git that get the latest version from the remote branch to the Local:
1. Git fetch: the equivalent of getting the latest version from remote to local, not automatically merge

Git fetch origin master
git log-p master. Origin/master
git merge Origin/master

First download the latest version from the Remote Origin master branch to the Origin/master branch
Then compare the differences between the local master branch and the Origin/master branch
The final merge
The above process can actually be done in a clearer way:

Git fetch Origin master:tmp
GIT diff tmp
Git merge tmp

Get the latest version from the remote to the local test branch
Then compare the merge

2.git Pull: the equivalent of getting the latest version from remote and merge to local

Git pull Origin Master

The above command is actually equivalent to git fetch and git merge

In practice, git fetch is a bit more secure, because before the merge, we can review the update and then decide whether to merge it.
