Git常用命令及操作总结

利用TortoiseGit克隆源码库到本地
1、安装TortoiseGit
2、打开Git,进入到源码库,点击图示红色选框框选按钮,弹窗界面中复制链接
2、进入要存放源码库的本地目标目录(比如:E:\Git),右键鼠标-选择Git-Clone,
弹出如下界面
3、如上图,按默认配置,点击Ok 按钮,弹窗密码输入框中输入密码,点击Ok
就这样,会把远程代码的master分支下载到本地目录(例中为 E:\Git\ddt-core-web)。
注:只会克隆master分支到本地
常用命令总结
git clone
git clone [option] <</span>版本库url> <</span>本地目录>
例:下载源码库master分支到本地E:\Git\ddt-core-web目录
git clone --progress -v "http://01094711@10.116.218.109:8080/scm/ddt/ddt-core-web.git" "E:\Git\ddt-core-web"

git
remote
Git要求每个远程主机都必须指定一个主机名。git remote命令就用于管理主机名。
例:
cd E:\Git\ddt-core-web\
注:除git colne命令外,git remote及以下命令的执行,都要先进入克隆的版本库所在的本地库目录才可以执行,否则会提示类似如下错误
fatal: Not a git repository (or any of the parent directories): .git
列出所有远程主机
E:\Git\ddt-core-web>git remote
origin
使用-v选项,可以参看远程主机的网址
E:\Git\ddt-core-web>git remote -v
origin http://01094711@10.116.218.109:8080/scm/ddt/ddt-core-web.git (fetch)
origin http://01094711@10.116.218.109:8080/scm/ddt/ddt-core-web.git (push)
输出说明当前只有一台远程主机,叫做origin,以及它的网址
查看主机的详细信息(git remote show <</span>远程主机名>)

git fetch

注意:默认情况下,git fetch取回所有分支(branch)的更新。如果只想取回特定分支的更新,可以指定分支名
取回远程主机的指定分支(git fetch 远程主机名 分支名)
E:\Git\ddt-core-web>git fetch origin master

* branch master -> FETCH_HEAD
例中意在取回orgin远程主机上名为master的分支
git check out
执行fetch命令,取回远程主机的更新后,便可使用git check out命令来建立本地分支
git checkout -b -newbranch []
创建新的分支并切换到新分支上去,b代表branch的意思,newbranch 是本地分支的名称,如果本地分支名已经存在, 则不需要“-b”选项。如果没有指定提交点(start_point),默认从HEAD指向的提交创建分支。
在指定分支的基础上,新建本地分支
E:\Git\ddt-core-web>git checkout -b newBranch origin/master
Branch newBranch set up to track remote branch master from origin.
Switched to a new branch 'newBranch'
以上命令的执行,会在origin/master的基础上,新建newBranch分支
说明:
1、创建本地分支并不会新建对应名称的文件夹;
2、新建分支后,会自动切换当前分支为新建的本地分支,如下
E:\Git\ddt-core-web>git branch -a
master
* newBranch
remotes/origin/HEAD -> origin/master
remotes/origin/master
……
再新建一个本地分支newBranch2
E:\Git\ddt-core-web>git checkout -b newBranch2 origin/master
Branch newBranch2 set up to track remote branch master from origin.
Switched to a new branch 'newBranch2'
E:\Git\ddt-core-web>git branch -a
master
newBranch
* newBranch2
……
切换当前分支为其它某个已存在分支(git checkout )
E:\Git\ddt-core-web>git checkout newBranch
Switched to branch 'newBranch'
Your branch is up-to-date with 'origin/master'.
E:\Git\ddt-core-web>git branch -a
master
* newBranch
……

git merge
在本地分支上合并指定分支。
E:\Git\ddt-core-web>git merge newBranch2
Already up-to-date.
以上命令的执行会把newBranch2分支合并到当前分支上
把origin/master分支合并到当前分支上
E:\Git\ddt-core-web>git merge origin/master
Already up-to-date.

git pull
git pull命令的作用是,取回远程主机某个分支的更新,再与本地的指定分支合并。
git pull <<font face="宋体">远程主机名> <</font>远程分支名>:<</font>本地分支名>
例,取回origin主机的master分支,与本地的newBranch分支合并
E:\Git\ddt-core-web>git pull origin master:newBranch

取回origin/master分支,再与当前分支合并。实质上,这等同于先做git fetch,再做git merge。
git fetch origin
git merge origin/next
如果远程分支是与当前分支合并,则冒号后面的部分可以省略
E:\Git\ddt-core-web>git pull origin master

在某些场合,Git会自动在本地分支与远程分支之间,建立一种追踪关系(tracking)。比如,在git clone的时候,所有本地分支默认与远程主机的同名分支,建立追踪关系,也就是说,本地的master分支自动”追踪”origin/master分支。
Git也允许手动建立追踪关系。
git branch --set-upstream master origin/next
上面命令指定master分支追踪origin/next分支。
如果当前分支与远程分支存在追踪关系,git pull就可以省略远程分支名
E:\Git\ddt-core-web>git pull origin
Password for 'http://01094711@10.116.218.109:8080':
Already up-to-date.
上面命令表示,取回当前分支与对应的origin主机”追踪分支”(remote-tracking branch),与本地的当前分支进行合并。
如果当前分支只有一个追踪分支,连远程主机名都可以省略
E:\Git\ddt-core-web>git pull
Password for 'http://01094711@10.116.218.109:8080':
Already up-to-date.
如果远程主机删除了某个分支,默认情况下,git pull 不会在拉取远程分支的时候,删除对应的本地分支。这是为了防止,由于其他人操作了远程主机,导致git pull不知不觉删除了本地分支。但是,你可以改变这个行为,加上参数 -p 就会在本地删除远程已经删除的分支。
$ git pull -p
# 等同于下面的命令
$ git fetch --prune origin
$ git fetch -p
git pull --rebase
如果采用git rebase呢,git rebase命令会把你的当前分支里的每个提交(commit,上次 pull 之后的变更)取消掉,并且把它们临时保存为补丁(patch)(这些补丁放到".git/rebase"目录中),然后合并远程分支到当前分支,最后把保存的这些补丁应用到当前分支上
