Git Fetch/pull Get the latest version from the remote branch to the local

There are 2 commands in git that get the latest version from the remote branch to the Local:

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

Compare merge after getting latest version from remote to local test branch

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 executing git merge after executing git fetch first.

Git fetch is a bit more secure in real-world use. Because before the merge, we can review the update and then decide whether to merge
