In the simplest terms, git pull does a git fetch followed by a git merge .

(用最简单的术语来说， git pull进行git fetch然后进行git merge 。)

You can do a git fetch at any time to update your remote-tracking branches under refs/remotes/<remote>/ .

(您可以随时执行git fetch来更新refs/remotes/<remote>/下的远程跟踪分支。)

This operation never changes any of your own local branches under refs/heads , and is safe to do without changing your working copy.

(此操作绝不会更改refs/heads下您自己的任何本地分支，并且可以安全地执行而不更改您的工作副本。)

I have even heard of people running git fetch periodically in a cron job in the background (although I wouldn't recommend doing this).

(我什至听说有人在后台执行cron作业中定期运行git fetch （尽管我不建议这样做）。)

A git pull is what you would do to bring a local branch up-to-date with its remote version, while also updating your other remote-tracking branches.

(git pull是您要执行的操作，以使本地分支的远程版本保持最新，同时还更新其他远程跟踪分支。)

(Git文档– git pull ：)

In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD .

(在默认模式下， git pull是git fetch简写，其次是git merge FETCH_HEAD 。)
