“ git fetch”在回购上没有任何作用

Question

I noticed with git log origin/master that new a commit is up. So I want to "see" this commit on my local repo.

I do this

$ git fetch -v
From xxx.xxx:proj/test
= [up to date]      master     -> origin/master

Everything seems fine... But nothing has changed on my local repo !?

To update your branches (as opposed to your Git's memory of some other Git's branches— git fetch updates this memory only), you must run a second Git command.

The second command to run is sometimes git merge and sometimes git rebase , depending on how you prefer to work. If you have no preference yet, use either one until you do have a preference.

There is a convenience command spelled git pull , that runs both git fetch and then the second command. The second command it runs is the one you tell it to. You must configure it based on your choice of second command to use. I recommend avoiding this until you really understand what the second command is and does, because eventually something will go wrong when running the second command. If you do not know that git pull is running this second command, you will not only not know what to do about this failure ... you won't even know that you need to look for how to fix problems with the other command!
