【Git常用命令總結】
前言：本人技術有限，如有說得不對或做的不對的地方，請大家提出來，謝謝大家
一、
Git介紹：
Git：是可以提供版本控制的一個工具
Github：提供了你用git這個工具的一個平臺，公共代碼倉庫
git服務器：自建倉庫，私有倉庫（企業用）
二、
Git和SVN的區別
Git是分布式版本控制系統，SVN是集中式版本控制系統
SVN的工作流程?
SVN有一臺中央服務器，下面有一臺至多臺的客戶端，完全依賴于中央服務器工作
SVN工作流程：
客戶端通過把內容Check out到本地，然后提交到中央服務器，后面再更新，然后再提交
弊端：1、如果中央服務器斷網了，則會導致無法更新
? ? 2、如果網絡不好，則會導致更新緩慢
? ? 3、如果中央服務器單點故障，又沒及時更新的話，則會導致數據丟失
架構圖：
三、
Git優點：
1、Git沒有中央管理器，每個人的電腦就是一臺完整的版本庫
2、工作不需要聯網，因為版本都在自已的電腦上
3、如果多個人共同協作，只需要push到github倉庫上即可進行多人協作
4、項目提交到GitHub，每一次提到到本地操作，都是一次對代碼倉庫的完整備份
架構圖：
上圖Git服務器是企業內部自已搭的私有的，如果是自已玩的，我們自已的電腦就是自已的倉庫，我們不需要聯網，然后有一個GitHub是公共倉庫，我們還可以把自已的項目提交到公共倉庫，相當于對自已代碼又做了一個備份，而企業內部，則需要自建一臺私有的Git服務器，大家通過先把代碼提交到自已電腦的倉庫，然后再提交到Git服務器這樣的一個工作流程
Git文件三種狀態
已提交（committed）
表示該文件已經被安全地保存在本地數據庫中了
已修改（modified）
表示修改了某文件，但還沒有提交保存
已暫存（staged）
表示把已修改的文件放在下次提交時要保存的清單中
Git文件流轉時的三個工作區域：
Git的工作目錄：
保存著特定的版本文件，屬于提交狀態
暫存區域：
做了修改并已放入暫存區域
本地倉庫:
顧名思義，本的版本倉庫
Git工作流程:
1、在工作目錄中修改某些文件
2、對修改后的文件進行快照，然后保存到暫存區域
3、提交更新，將保存在暫存區域的文件快照永久轉儲到Git目錄中
【實戰】
一、Git準備工作
1)cygwin和git bash的對比
由于我們在Windows上執行git的命令需要一個仿Unix終端的軟件，在這里，我給大家介紹兩款軟件，一款是cygwin，一款是git bash，git bash是git提供給你用的軟件，那么這兩款軟件有啥不一樣呢，請看圖：
1、左邊那款是git bash，他能夠把你當前用戶家目錄所有文件包括windows的都列出來，而右邊的cygwin只列出他用戶家目錄的文件，并沒有列出windows的文件
總結第一點：cygwin簡潔性強，而bit bash把windows家目錄的東西都列出來，讓你也可以進行操作，至于你覺得哪個好，這個看你個人喜好
再來看第二張圖
2、左邊那款還是git bash，右邊那款則是cygwin，兩者都在f盤下執行了ls，看到兩者不什么不一樣了嗎，git bash能把文件夾以高這度藍色顯示，而cygwin不管你是什么文件都是白色，這個倒是讓我們不好區分
總結第二點：覺得這個高這度顯示各種不一樣的文件這個優越性git bash是做的比較好的
我的選擇：git bash
為什么 ？
因為git bash不緊可以高亮度顯示各種不一樣的文件，讓你可以快速操作，而且在家目錄下他也可以列出你的所有windows下的文件，提供給你操作，我覺得選擇git bash還是比選擇cygwin好的，不過這個最終還是看你自已個人選擇，我在這里只是說出我自已的想法而已
2）下載安裝
git下載鏈接：https://git-scm.com/download/win
我的安裝是默認一路向北
cygwin下載鏈接：https://cygwin.com/install.html
安裝教程：http://jingyan.baidu.com/article/6b97984d83dfe51ca2b0bf0e.html
3）桌面右健鼠標點擊Git Bash Here打開Git Bash，界面如下：
它是在Windows下模仿Shell命令行的一個終端
4）查看幫助
Administrator@YYBFVJDMAPF13NB?MINGW64?~/Desktop $?git?help?git?????????#git?help?<verb>Administrator@YYBFVJDMAPF13NB?MINGW64?~/Desktop $?git?config?--help????#git?<verb>?--help5）設置身份
因為git是分布式版本控制系統，所以需要填寫用戶名和郵箱做為一個標識
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?config?--global?user.name?'wsyht'Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?config?--global?user.email?t89191958201@139.com注意：git config 下有三個參數，
--global: 表示對這臺機器上的所有Git倉庫都會使用這個配置
--system：用戶級別配置，針對某個用戶生效
--local：針對本地有效
6）設置比較工具（可選）
Administrator@YYBFVJDMAPF13NB?MINGW64?~/Desktop $??git?config?--global?merge.tool?vimdiff7）檢查配置
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?config?--list core.symlinks=false core.autocrlf=true core.fscache=true color.diff=auto color.status=auto color.branch=auto color.interactive=true help.format=html http.sslcainfo=C:/Program?Files/Git/mingw64/ssl/certs/ca-bundle.crt diff.astextplain.textconv=astextplain rebase.autosquash=true merge.tool=vimdiff user.name=wsyht user.email=t89191958201@139.com core.repositoryformatversion=0 core.filemode=false core.bare=false core.logallrefupdates=true core.symlinks=false core.ignorecase=true二、創建版本庫
1）（關健字：git init）
版本庫：又名倉庫，你可以簡單的理解成一個目錄，這個目錄里面的所有文件都可以被Git管理起來，包括修改、刪除、提交、回滾
Administrator@YYBFVJDMAPF13NB?MINGW64?~/Desktop $?cd?f:?Administrator@YYBFVJDMAPF13NB?MINGW64?/f $?mkdir?demo1Administrator@YYBFVJDMAPF13NB?MINGW64?/f $?cd?demo1/Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1 $?git?init Initialized?empty?Git?repository?in?F:/demo1/.git/Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $這個時候會多了一個.git的隱藏目錄，他是用來管理跟蹤管理版本的，里面文件不可以修改
2）提交任務(關健字：git add,git commit)
3）查看狀態（關健字：git status）
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?status On?branch?master nothing?to?commit,?working?tree?cleanAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $4）修改裝態查看?（關健字：git status,modify）
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?ls demo1.txtAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?echo?"1111"?>>?demo1.txtAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?status On?branch?master Changes?not?staged?for?commit:(use?"git?add?<file>..."?to?update?what?will?be?committed)(use?"git?checkout?--?<file>..."?to?discard?changes?in?working?directory)modified:???demo1.txt????#修改裝態 no?changes?added?to?commit?(use?"git?add"?and/or?"git?commit?-a") Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master)5）對比查看?（關健字：git diff）
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?diff?demo1.txt diff?--git?a/demo1.txt?b/demo1.txt index?a5bce3f..979b2de?100644 ---?a/demo1.txt +++?b/demo1.txt @@?-1?+1,2?@@test1 +1111???????#可看出多了這一行 warning:?LF?will?be?replaced?by?CRLF?in?demo1.txt. The?file?will?have?its?original?line?endings?in?your?working?directory.Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $注意：提交前須查看一下文件修改的內容，如不問題，再git add，然后git commit
6）查看提交歷史記錄（關健字：git log）
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?log commit?8445579cbd259610f94a6c665fc841313a131516???#每次提交的版本號 Author:?wsyht?<t89191958201@139.com> Date:???Thu?Jul?28?23:15:40?2016?+0800文件增加2222一行???????????????????????????????#增加內容顯示的注釋，最近的一次提交，從上到下排序 commit?25e4895bd19c0833fa75d4b71ec8d621f3cbe2e7 Author:?wsyht?<t89191958201@139.com> Date:???Thu?Jul?28?23:15:08?2016?+0800增加1111一行 commit?a7e593c34a10f0b2e732153c09bce74381e7de35 Author:?wsyht?<t89191958201@139.com> Date:???Thu?Jul?28?22:56:25?2016?+0800demo1提交Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $注意：剛才是我自已做實驗一共提交了三次，并未貼出來到博客而已，所以出現了三次提交的歷史記錄
7）省略部分信息 （關健字：--pretty=oneline）
三、版本回退
1）回退命令
? ?1、回退到上一個版本
????? git reset --hard HEAD^
? ?2、回退到上上一個版本
??????git reset --hard HEAD^^
? ?3、回退到前100個版本
???? ?git reset --hard HEAD~100
演示：
回退到上一個版本
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?cat?demo1.txt test1 1111 2222Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?reset?--hard?HEAD^ HEAD?is?now?at?25e4895?增加1111一行Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?cat?demo1.txt test1 1111Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?log commit?25e4895bd19c0833fa75d4b71ec8d621f3cbe2e7 Author:?wsyht?<t89191958201@139.com> Date:???Thu?Jul?28?23:15:08?2016?+0800增加1111一行 commit?a7e593c34a10f0b2e732153c09bce74381e7de35 Author:?wsyht?<t89191958201@139.com> Date:???Thu?Jul?28?22:56:25?2016?+0800demo1提交Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $2)回退到剛才的最新版本
（1）首先獲取版本號 （關健字：git reflog）
（2）恢復版本（關健字：git reset --hard 版本號）
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?reset?--hard?8445579 HEAD?is?now?at?8445579?文件增加2222一行Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $（3）查看恢復

工作區：就是在我創建的demo1的版本庫目錄里的文件，.git目錄除外
版本庫：.git目錄就是版本庫，版本庫存著很多東西，其中最重要的就是stage（暫存區），還有Git為我們自動創建了第一個分支Master，以及指向Master的第一個指針HEAD，
提交Git文件到版本庫有兩步;
第一步：是使有tgit add把文件添加進去，實際上就是把文件添加到暫存區
第二步：使用git commit提交更改，實際上就是把暫存區的所有內容提交到當前分支上
演示：
（1）修改文件和創建新文件查看

如果在一行里面添加了新內容，現在要撤消
總結一下一共有三種方法：
第一種：把要刪除的內容添刪掉，然后add,commit
第二種：恢復上一個版本，git reset --hard HEAD^
第三種：如下 （關健字：git checkout -- 文件名）-- 很重要，請注意，這里說的是兩個'-'，如果沒有 -- 的話；那么命令變成切換分支了 或者用 git checkout . 推薦使用這個，可以批量還原修改的文件，前提是未add和commit，但是不包括新增的文件，只是針對已經存在文件且修改了內容的文件，進行撤消
$?cat?demo1.txt test1 1111 2222 3333 5555 Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?echo?"6666"?>>?demo1.txtAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?status On?branch?master Changes?not?staged?for?commit:(use?"git?add?<file>..."?to?update?what?will?be?committed)(use?"git?checkout?--?<file>..."?to?discard?changes?in?working?directory)modified:???demo1.txt no?changes?added?to?commit?(use?"git?add"?and/or?"git?commit?-a")Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?checkout?--?demo1.txtAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?cat?demo1.txt test1 1111 2222 3333 5555如果，已經add添加到暫存區的，那么撤銷方法如下
接著再如下圖操作，
如果新添加的文件，但是還沒有add，現在我們不想用這個新文件了，那么我們直接刪除就行了，如下：
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?echo?"111"?>>?wsyht.txtAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?status On?branch?master Untracked?files:(use?"git?add?<file>..."?to?include?in?what?will?be?committed)wsyht.txt nothing?added?to?commit?but?untracked?files?present?(use?"git?add"?to?track)Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?ls demo1.txt??oo.txt??wsyht.txt??ye.txtAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?rm?-rf?wsyht.txtAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?status On?branch?master nothing?to?commit,?working?tree?cleanAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $五、刪除文件和恢復
（1）刪除演示

三種情況
1、未add想轍消（包括增刪改文件內容，也包括刪文件）
? ?git checkout -- 文件名??（轍消工作區的修改）? ? 或
? ?git checkout .
2、add到暫存區后,需分兩步操作
? ?第一步：git reset HEAD 文件名??（轍消暫存區的修改）
3、commit之后
? ?git reset --hard HEAD^ ? ? ?#版本回退1個版本
? ?git reset --hard HEAD^^ ? ? #版本回退2個版本 ??
? ?git reset --hard HEAD~100 ? ?#回退到前100個版本
???? ?git reflog ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?#獲取版本號
? ? ??git reset --hard 版本號 ? ? ? ? ? ? ? ?#恢復版本號
? ? ?
六、遠程倉庫（GitHub公共倉庫）
1）先注冊github賬號
省略...
2）生成ssh-keygen密鑰對

4、創建展示
5、完成展示
在如上截圖顯示內容我要說一下了
通過本地倉庫和GitHub倉庫的連接方式有兩種：
第一種：通過HTTPS方式連接，就是如上紅框顯示，這種方式在本地遠程GitHub倉庫，需要用輸入你的GitHub賬號和密碼，而且每次都要輸入 ?缺點：不安全，麻煩
第二種：通過ssh方式連接，在本地創建密鑰對， 再把公鑰上傳到GitHub服務器，然后實現無密碼連接如下截圖這是通過ssh的連接方式: ? ? 優點：安全，方便
先說第一種連接方式：
這種方式是通過第一種https連接方式，先進入到我的工作目錄下，也就是創建的版本庫目錄下，
然后輸入遠程命令，用戶名和密碼即可
第二種方式展示
上面已經生成了密鑰對了，然后我們把id_rsa.pub的公鑰復制到GitHub上去
本地測試
修改配置文件，進到版本庫目錄.git下，修改config文件 Administrator@YYBFVJDMAPF13NB?MINGW64?~/.ssh $?cd?f:Administrator@YYBFVJDMAPF13NB?MINGW64?/f $?cd?demo1/.git/Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/.git?(GIT_DIR!) $?ls COMMIT_EDITMSG??description??hooks/??info/??objects/???refs/ config??????????HEAD?????????index???logs/??ORIG_HEAD Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/.git?(GIT_DIR!)$vim config
如上圖所示，原本默認是https的連接方式，現在改成通過ssh方式去連接，只需要把giuhub剛創建項目時他顯示的連接命令考到config文件url后面即可
測試連接：

現在我們再更改一個文件，然后再Push到github
先提交到本地

.config文件展示
剛剛上面執行git remote rm origin就是把url那一行刪了
接著又執行了git remote add origin git@github.com:wsyht/demo_test.git
相當于重新加載了那一行，所以又能push上了，push即是推送文件上去github公共倉庫里
wsyht是我建注冊的github的用戶名，demo_test是我在GitHub上建的項目名，git是用戶名，github.com是github網站的域名,origin是遠程倉庫默認的庫名
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/.git?(GIT_DIR!) $?cat?config [core]repositoryformatversion?=?0filemode?=?falsebare?=?falselogallrefupdates?=?truesymlinks?=?falseignorecase?=?true [branch?"master"] [branch?"master"] [branch?"wsyht"] #[alias]#br?=?branch [remote?"origin"]url?=?git@github.com:wsyht/demo_test.gitfetch?=?+refs/heads/*:refs/remotes/origin/*再查看github
OK，已經提交上去了
現在我們再來看一下config這個配置文件
Administrator@YYBFVJDMAPF13NB MINGW64 /f/demo1/.git (GIT_DIR!)
$ cat config
[core]
? ? ? ? repositoryformatversion = 0
? ? ? ? filemode = false
? ? ? ? bare = false
? ? ? ? logallrefupdates = true
? ? ? ? symlinks = false
? ? ? ? ignorecase = true
[branch "master"]
[remote "origin"]
? ? ? ? url = git@github.com:wsyht/demo_test.git ? #這一行是講你所用的連接方式
? ? ? ? fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
? ? ? ? remote = origin ? ? ? ? ? ? ?
? ? ? ? merge = refs/heads/master ? ? #合并分支是master，到后面我再講什么是分支
注意：在第一次我們推送master分支時，加上了-u參數，git會本地的Master分支推送到github的master分支，并且會關聯起來，所以的就不需要再加入-u參數了
七、遠程庫克隆到本地
點擊進去
刪除提交后，現在我們在把GitHub克隆到本地，你會發現少了一個文件
本地操作：關健字： git clone
可以看到多了一個目錄出來
八、GitHub刪除項目
九、分支的創建與合并
首先我們來講一下什么是分支，分支就相當于我現在在做一個項目A，然后項目里面有一個功能的BUG我需要去做修改，然后為了安全，不影響我的Master分支，我就在我的Master分支上再創建一個分支出來，然后我就在我這個分支上修改我的代碼，修改完成后，再與我的Master主分支合并，這樣就不會影響到我的原文件，分支其實就是基于某一時刻的代碼進行修改，這個分支實際上只存儲這些修改，也可以說是項目某個時期的快照，但他不是真實賦值文件，修改完成后，合并到Master分支，這樣，Master分支的內容從而也會跟著發生改變，而創建的臨時文件，則怎么修改也不會影響我的源文件，即Master分支的內容，相當于你在虛擬機的一個測試環境，你愛昨玩昨玩，都不會影響到我的真實系統
1）創建分支wsyht 關健字：git checkout -b 分支名字 ，git branch
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(master) $?git?checkout?-b?wsyht?????????#創建并切換分支 Switched?to?a?new?branch?'wsyht'Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(wsyht) $?git?branch????#查看當前所在分支master *?wsyht???Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(wsyht) $git branch wsyht ? #創建分支
git checkout wsyht #切換分支
在wsyht分支上進行修改內容提交操作?
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(wsyht) $?echo?"999"?>>?demo1.txtAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(wsyht) $?git?add?demo1.txt warning:?LF?will?be?replaced?by?CRLF?in?demo1.txt.

現在合并分支
把Master分支和wsyht分支內容合并在一起，只留Master分支，再看Master分支的內容，關健字：git merge wsyht
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(master) $?git?branch *?masterwsyhtAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(master) $?git?merge?wsyht Updating?3020d4c..c4ff9ea Fast-forwarddemo1.txt?|?1?+1?file?changed,?1?insertion(+)Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(master) $?cat?demo1.txt test1 1111 2222 3333 5555 777 888 999Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(master) $Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/demo_test?(master) $??git?branch?-d?wsyht Deleted?branch?hb?(was?5939679).可查看到，在wsyht分支上修改的內容，合并后，在Master分支上已顯示出來
注意：在創建的臨時分支上修改了文件內容后，此時主分區不能進行合并，一定要add，commit了然后再在主分區上進行合并操作，合并后，要刪除臨時分支，否則分支了多會凌亂，合并后可以通過git log -1查看最新合并的日志，合并后無需再做任何操作，直接push到git服務器或GitHub即可
命令總結
查看分支：git branch
創建分支：git branch 分支名字
切換分支: git checkout 分支名字
創建切換分支: git checkout -b 分支名字
合并某分支到當前分支: git merge 分支名字
刪除分支: git branch -d 分支名字
十、分支合并沖突解決

在合并分支時，默認會用fast forware模式，這樣的話在我們刪除分支后，會刪掉我們曾經合并過的信息，此時，你再用git log就查看不了我們跟哪些分支做過合并了，所以在合并的時候我們要加上一個參數，--no-ff

第一個要注意的地方：如下可以看到git切換到wsyht分支，但是wsyht分支沒有add和commit，所以再切回master，他就相當于直接改了Master的文件，所以修改了一定要，add再commit后再切回Master
第二個要注意的地方：當你在其他分支上修改了文件提交后，合并到Master后，一定要刪了開出來的分支，然后再開新的分支用，畢免二次污染

我在這里講一句：實踐出真知，有時候想一些東西，還不如親自動手操作明白來得快，有些地方你想來想去不明白，但你動手操作了，你就明白他是怎么一回事了，所以不要光看不練，相信我，下面對于屬于開發比較復雜的項目的開發來說很重 ，請大家認真看
#這里是指使用第一個分支開發，但是還沒開發完新功能，所以并未能add提交，這個時候上頭又說要馬止改一個很重要的bug，要快速完成，所以我們在把這個分支儲藏起來，下次回來再拿出來繼續開發
第一步：
#第一個wsyht分支操作 ??

第二個bug分支操作
bug分支修改->提交-合并-刪除bug分支
第三步：
#回到第一個分支wsyht操作
合并master分支->調回wsyht修改狀態->add提交
合并master分支主要就是先把剛剛修改的bug先合并了，然后再調回剛才修改的狀態，繼續開發提交

#主分支Master操作
切回主分支->合并wsyht分支->add提交->刪除wsyht分支

第一步：第一分支開發修改、然后儲藏狀態
第二步：從第一分支切回Master分支，再創建并切去第二分支，開發修改，提交，并合并到Master分支，刪除第一分支
第三步：從Master分支切到第二分支，并在第二分支合并Master分支，恢復第二分支修改狀態，繼續修第四步：從第二分支再切回Master分支，并合并第二分支修改的內容，刪除第二分支
分支命令總結：
查看分支合并情況
git log --graph --pretty=oneline --abbrev-commit ? #--graph圖形化顯示，--pretty=oneline簡短顯示，--abbrev-commit驗證碼省略顯示
git stash????#儲藏內容
git stash list ? #查看儲藏內容
git stash pop/git stash apply ? ?#恢復上一個工作內容
二者不同的是git stash apply恢復后，stash內容并未刪除，你需要用git stash drop來刪除，而用git stash pop,恢復的同時把stash內容也刪了
十四、強制刪除分支
當我們在某第二個分支開發某一個功能，提交分支之后，回頭策劃卻說還是不要改了，這個時候我們不能合并分支，只能刪除第二個分支
如下：

十五、多人協作
當在你提交或幫隆的時候會自動幫你把本地和遠程的master分支對應起來，遠程庫的默認名稱是origin
#查看遠程庫
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?remote???#查看遠程庫的信息 originAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $?git?remote?-v????#查看遠程庫的詳信息 origin??git@github.com:wsyht/demo_test.git?(fetch) origin??git@github.com:wsyht/demo_test.git?(push)Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(master) $上面顯示了可以抓取和推送的origin的地址。如果沒有推送權限，就看不到push的地址
#推送分支
推送分支就是把本地的分支提交到對應的遠程庫的分支中，如果是Master分支就提交到遠程庫的Master分支，如果是其它分支如wsyht，就提交到遠程庫的wsyht分支中與之相對應，如果一些bug分支不需要提交的，就把他先主分支先合并了，然后再提交到遠程庫中

2）多人同推沖突
現在假如有兩個人兩臺電腦共同推一個分支的文件，假如我先推了，張三也又接著推了，張三就會報錯推不上去，這個時候，我們來看看怎么操作
角色：“我” 和 “張三”
首先我的在我的電腦上創建一個wsyht分支用來做開發，因為master分支張三是無法拉取下來做開發的，所以只能搞一個wsyht分支，在wsyht分支上做開發，開發完成功能后，提交wsyht分支，然后push到git服務器，再合并master分支，然后把master分支提交，push到git服務器
我的電腦操作，如下：
流程：創建分支->切換分支->推送 ? #此分支一般工作中事先存在，而我這里為了做事驗，所以臨時創建

十六、創建工作目錄的兩個方法
第一種、就是上面張三用的方：，git init后，然后使用取得遠程庫的分支，創建遠程庫的分支
現在我們來演示第二種方法：git clone
當來了一位新員工，我們就給克隆git的項目下來給他開發推送

忽略push的文件很簡單，只需要在你的工作區目錄下創建一個特珠的.gitignore文件，然后把忽略的文件名或文件尾輟填進去即可，但在windows下你是創建不了.xxx的文件，他會提示你輸入文件名，這個時候你可以用編輯器另存為就可以創建出這個文件
如：
如果你添加的某個文件被忽略了，但你又想添加，
有兩種方法解決：第一：修改.gitignore文件
????????????????第二：就是強制執行他
第一種方法：查看要添加的那個文件在.gitignore的哪一行設置了忽略，然后去修改.gitignore文件
git?check-ignore?-v?xx.xx??#xx.xx是被忽略的那個文件第二種方法：加上-f 強制添加執行
git?add?-f?xx.xxGitHub也為我們準備了各種配置文件，大家可以參考一下

#本地操作
連接方式是 git clone git@server ip:/倉庫路徑/倉庫目錄名字
Administrator@YYBFVJDMAPF13NB?MINGW64?/f $?mkdir?demo2Administrator@YYBFVJDMAPF13NB?MINGW64?/f $?cd?demo2Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo2 $?git?clone?git@192.168.1.102:/usr/local/wsyht.git Cloning?into?'wsyht'... remote:?Counting?objects:?11,?done. remote:?Compressing?objects:?100%?(4/4),?done. remote:?Total?11?(delta?0),?reused?0?(delta?0) Receiving?objects:?100%?(11/11),?done.

注意：我在本地push文件到Git服務器后，因為創建的這個是裸倉庫是沒有工作區的，所以他的存文件的方式是不一樣的，貌似是以什么進制方式存著，所以你在Git服務器里是找不到他的文件的，這個很正常，他是占用服務器的磁盤空間的
這個是Git服務器存取分支目錄：
/usr/local/wsyht.git/refs/heads/
當我在本地創建了新分支的時候，則所有分支文件會在上面目錄下顯示出來
如下我又創建了一個wsyht分支，則在服務器上又顯示一個wsyht的普通文件
[root@localhost?heads]#?pwd /usr/local/wsyht.git/refs/heads [root@localhost?heads]#?ll 總用量?8 -rw-rw-r--?1?git?git?41?7月??31?21:12?master -rw-rw-r--?1?git?git?41?7月??31?21:20?wsyht而這個目錄是存儲標簽內容，這里我就不再一一演示了
[root@localhost tags]# pwd
/usr/local/wsyht.git/refs/tags
報錯展示：
1）因為git服務器里的git用戶禁止登陸了，本地clone不上所以報的錯
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/KuGou $?git?clone?git@192.168.1.102:/usr/local/wsyht.git Cloning?into?'wsyht'... fatal:?protocol?error:?bad?line?length?character:?This解決方法：讓git可以登陸，但不用設密碼，因為人我們是用key去連的，這樣才安全
2）因為git權限不夠報的錯

二十、鉤子腳本
SVN常用腳本：pre-commit，post-commit
Git常用腳本：post-receive
SVN和Git的pre-commit說明
這是提交要執行的動作，沒什么好說的，不一樣的是Git是在本地執行動作
SVN和Git的post-commit說明
這是提交后要執行的操作，也沒什么好說的，同理，不一樣的是，Git他提交后執行的動作是在本地執行的，因為他提交的內容是提交到本地倉庫，他本地就是一個倉庫
Git的 post-receive ? => 重點內容到了
Git的post-receive是當接到你在本地push內容到我的Git服務器后，觸發了我Git服務器的post-receive腳本去執行相應的動作，而這個要腳本里面要執行的這個動作就由你自已去定義
現在我們來演示一下
Git服務器作：
一定要先把文件復制出來，把后面的.sample去掉才能使用
從上圖可以看到，復制出來的post-receive權限不對，我們要先改權限
添加腳本要執行的內容
[root@bogon?hooks]#?echo?"/bin/touch?/tmp/test_wsyht.txt"?>>?post-receive??? [root@bogon?hooks]#?cat?post-receive #!/bin/sh # #?An?example?hook?script?for?the?"post-receive"?event. # #?The?"post-receive"?script?is?run?after?receive-pack?has?accepted?a?pack #?and?the?repository?has?been?updated.??It?is?passed?arguments?in?through #?stdin?in?the?form #??<oldrev>?<newrev>?<refname> #?For?example: #??aa453216d1b3e49e7f6f98441fa56946ddcd6a20?68f7abf4e6f922807889f52bc043ecd31b79f814?refs/heads/master # #?see?contrib/hooks/?for?a?sample,?or?uncomment?the?next?line?and #?rename?the?file?to?"post-receive". #.?/usr/share/git-core/contrib/hooks/post-receive-email /bin/touch?/tmp/test_wsyht.txt因為/tmp目錄下是所有用戶都有讀、寫、執行的，如果要對其他目錄有讀寫執行權限，必須得先把所有者所屬組改成Git，然后再給他相應的讀、寫、執行權限即可，
再查看一下/tmp目錄下的內容，目前沒有test_wsyht.txt文件
[root@bogon?hooks]#?ls?/tmp/ keyring-R8s7ni??pulse-gbg3wjQuvzvI??virtual-root.cNwkfe??vmware-config0 orbit-gdm???????pulse-zqLc6oaaNKa9??virtual-root.D0hQX0??VMwareDnD orbit-root??????ssh-hotQgm2726??????virtual-root.KIVXJC??vmware-root好，到這一步，我們的Git服務器就算配置完了
本地操作：
提交和push

【拓展知識】
一、別名配置
法1：真接命令行配置
輸入--global是對當前用戶起作用的，如果不加只對當前倉庫起作用
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo2?(wsyht) $?git?config?--global?alias.st?status???#把status?配置成別名?stAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo2?(wsyht) $?git?config?--global?alias.co?checkout?#把checkout?配置成別名?coAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo2?(wsyht) $?git?config?--global?alias.ci?commit???#把commit?配置成別名?ciAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo2?(wsyht) $?git?config?--global?alias.br?branch???#把branch?配置成別名?brAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(wsyht) $?git?config?--global?alias.unstage?'reset?HEAD'Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(wsyht) $?git?config?--global?alias.last?'log?-1'Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo2?(wsyht) $?git?status???#用原來的命令查看狀態 On?branch?wsyht Your?branch?is?up-to-date?with?'origin/wsyht'. nothing?to?commit,?working?tree?cleanAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo2?(wsyht) $?git?st???????#用別名查看狀態，成功了，其他別名同樣使用方法，這里不再一一演示 On?branch?wsyht Your?branch?is?up-to-date?with?'origin/wsyht'. nothing?to?commit,?working?tree?clean法2：配置文件配置
我們可以改兩個配置文件
首先先說第一個配置文件，我們在命令行輸入命令--global設置別名，也是把命令寫進這個文件的，我們也可以進到這個文件修改，他就是你家目錄下的.gitconfig，敲cd回車就可以回到你的家目錄
第一個配置文件配置
可以看到.gitconfig文件寫入了我在命令行設置別名的命令，如果你加--global就會寫入這個配置文件，你也可以直接進到這個文件添加，而不在終端執行命令，要刪除別名的話進到這個文件把相應的別名命令刪除即可，這個文件是針對當前用戶生效的
第二個配置文件
在倉庫目錄下.git/config目錄下，此配置文件，是針對當前倉庫有效，所以在當你在終端執行命令的時候不加--global就會把命令寫入這個文件，你也可以進到這個文件進行添加刪除別名命令，下面我們來看配置文件內容
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/.git?(GIT_DIR!) $?pwd /f/demo1/.gitAdministrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1/.git?(GIT_DIR!) $?cat?config [core]repositoryformatversion?=?0filemode?=?falsebare?=?falselogallrefupdates?=?truesymlinks?=?falseignorecase?=?true [branch?"master"] [remote?"origin"]url?=?git@github.com:wsyht/demo_test.gitfetch?=?+refs/heads/*:refs/remotes/origin/* [branch?"master"]remote?=?originmerge?=?refs/heads/master [branch?"wsyht"]remote?=?originmerge?=?refs/heads/wsyht #[alias]#br?=?branch添加方法一樣，跟上面的第一個配置文件.gitconfig一樣，這里我只是為了演示，所以我把他注釋掉了
二、標簽操作
1）創建標簽
2）刪除和push標簽
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(wsyht) $?git?tag?-d?v0.3 Deleted?tag?'v0.3'?(was?784bb96)Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(wsyht) $?git?tag v0.4 v1.0 v1.1Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(wsyht) $?git?push?origin?v0.4??#提交單個標簽 Counting?objects:?1,?done. Writing?objects:?100%?(1/1),?180?bytes?|?0?bytes/s,?done. Total?1?(delta?0),?reused?0?(delta?0) To?git@github.com:wsyht/demo_test.git*?[new?tag]?????????v0.4?->?v0.4Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(wsyht) $?git?push?origin??--tags???#提交所有標簽 Total?0?(delta?0),?reused?0?(delta?0) To?git@github.com:wsyht/demo_test.git*?[new?tag]?????????v1.0?->?v1.0*?[new?tag]?????????v1.1?->?v1.1在GitHub上查看
標簽都出來了，push成功
3）刪除遠程庫的標簽
Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(wsyht) $?git?tag?-d?v0.4 Deleted?tag?'v0.4'?(was?dea0b58)Administrator@YYBFVJDMAPF13NB?MINGW64?/f/demo1?(wsyht) $?git?push?origin?:refs/tags/v0.4 To?git@github.com:wsyht/demo_test.git-?[deleted]?????????v0.4可以看到，遠程庫的標簽已經刪除成功
最后再說一下，有的人說SVN有工作可以提交上傳，但是Git卻要敲命令，現在我告訴你Git也是有工具的，如果你不喜歡命令行的話，你可以去下載這個工具，github sourcetree?如下圖，這是我網上找來的圖片，界面就是這個樣子
但是我還想說，我還是喜歡用命令行，上面那個工具我沒用過，我相信大多數人都是用命令行，因為你通過命令行去做執行的話，你會更有滿足感，你操作速度會更快更靈活更有快感，而且你知道每一步的步驟，你也不會混亂，相信我，用命令行吧，我相信大多數人都是用命令git bash的，放棄這個工具吧
