The difference between git fetch and git pull __git

Git gets the latest version from the remote branch to the Local has such 2 commands:
1. Git fetch: the equivalent of getting the latest version from the remote to the local, does not automatically merge

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

Meaning of the above command:
First download the latest version from the Master Master branch of the remote origin 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 the following 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 the remote and merge to the local

Git pull Origin Master

The above command is actually equivalent to git fetch and git merge
In actual use, git fetch is more secure
Because before we merge, we can review the update and then decide whether to merge
