在使用版本号工具提交改动之前,都须要通过update先将本地代码更新到最新版本号。SVN通过svn update就能够实现,那么git怎样实现呢?
1. 首先通过从远程的origin的master主分支下载最新的版本号到本地origin/master分支上,然后比較差别,最后合并到当前分支;
[root@~/wade/nodejs/express-routing]# git fetch git@github.com:billfeller/express-routing.git master
From github.com:billfeller/express-routing
* branch master -> FETCH_HEAD
[root@~/wade/nodejs/express-routing]# git log

2. 通过git pull一步到位,相当于是从远程获取最新版本号并merge到本地,即第一种方法的快捷命令。
[root@~/wade/nodejs/express-routing]# git pull
remote: Counting objects: 3, done.
remote: Compressing objects: 100% (2/2), done.
remote: Total 3 (delta 1), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.

在实际开发中,还是推荐使用第一种方式,由于git fetch更安全一些,能够通过git fetch后查看更新情况,再决定是否进行合并。
