Git 分支

1.分支命名法則及常用命令

master（主干分支） 是指向指定分支的最近一次提交；

dev 是指向dev分支的最近一次提交；

不管有多少分支，活動(dòng)分支只能有一個(gè)；

head 一定是指向某個(gè)分支的，head表示? 映射了當(dāng)前工作目錄當(dāng)中所反映的最近一次提交；即 head始終指向活動(dòng)分支的最近一次提交；

★分支命名法則

  • 可以使用"/"，但不能使用"/"結(jié)尾；

  • 不能以 "-" 開頭；

  • 以位于 "/" 后面的組件，不能以 "." 開頭；

  • 不能使用連續(xù)的 "...";

  • 不能使用空白字符" "；

  • 不能使用"^","~","?","*","[" 等符號(hào)

必須唯一，分支的名字始終指向目標(biāo)分支的最近一次提交；

★git branch :列出，創(chuàng)建及刪除分支

  • git branch BRANCH_NAME [START_COMMIT]

  • git branch? -d??BRANCH_NAME? 刪除分支

★git show-branch：查看分支及其相關(guān)的提交

★git? checkout?

  • git? checkout? <branch> 檢出分支

Git 分支合并

1.分支合并--git merge

★相關(guān)概念

  • 合并基礎(chǔ)：要合并的分支的最近一次的共同提交；

  • 我們的版本：當(dāng)前分支的最近一次提交；

  • 他們的版本：要合并進(jìn)來的分支的最近一次提交；

☉無沖突合并：

  1. git checkout master;? ?檢出到主分支

  2. git status???檢查是否有未提交的信息

  3. git merge BRANCH_NAME???從他們的版本合并到我們的版本

  4. git log --graph --pretty=oneline --abbrev-commit? ?以圖形的方式查看

☉有沖突合并：

  1. 手動(dòng)解決沖突；

  2. 解決完成之后：git add ---> git commit

☉回退到合并之前的版本

  • git reset --hard ORIG_HEAD

1.git變基分支合并--git rebase

★變基操作

  • $ git checkout dev?: 首先切換到要變基的分支；

  • $ git rebase master： 把他的基從最近一次的共同祖先提交轉(zhuǎn)換為master的最新提交；

  • $ git checkout master ：回到master分支；

  • $ git merge -m "MSG"?：master 獲取新的提交。

演示：

[root@node1?taotao]#?git?checkout?master
Switched?to?branch?'master'
[root@node1?taotao]#?ls
