前言

git fetch 命令用于从远程获取代码库，从远端仓库提取数据并尝试合并到当前分支

用法

1、git fetch
git fetch origin

会显示

$ git fetch origin
remote: Enumerating objects: 116, done.
remote: Counting objects: 100% (93/93), done.
remote: Compressing objects: 100% (52/52), done.
remote: Total 62 (delta 28), reused 0 (delta 0)
Unpacking objects: 100% (62/62), done.
From http://github.comi:000/scm/adapt/cm
   d289cd3..360765e  feature_conformer-large -> origin/feature
   a72e376..43d0252  feature_yolov5          -> origin/feature_
   b45e6db..9d4636b  master                  -> origin/master

以上信息"b45e6db…9d4636b master -> origin/master" 说明 master 分支已被更新，我们可以使用以下命令将更新同步到本地：

2、git merge

git merge origin/master

展示

$ git merge origin/master
