Repository 使用GIT管理一个项目的时候，就需要一个仓库（repository）用于存放GIT对项目管理所必须要保存的各种文件，使用 git init 命令创建一个新的仓库。GIT会在当前目录下创建一个.git文件夹，用作仓库。然后，当你使用GIT记录每一次代码改动的时候，GIT就会把需要的信息都放到这个文件夹下面。 Commit 每当你完成一个改动（change）的时候，就可以commit一下，记录当前项目的情况（snapshot）。每一个commit包含如下信息： commit-id（sha-id） ：这是一个通过sha-1算法算出来的一个id，它不只作为每个commit的唯一识别码，也可以用来验证保存的代码是否损坏。所以在GIT在管理代码的时候，如果发生代码损坏，可以很有效的检测到。 author ：作者 date : 日期时间 log messge ：一段作者对代码改动的文字描述。 change-id ：如果是和repo、gerrit一起使用的话，repo会加上这个信息，以便在整个代码系统中识别同一个改动的多个版本。 用代码管理软件管理代码的时候，有个理念就是：每次改动提交以后，整个项目都应该是可以工作的。所以，每次commit最好都能是这样的的改动，虽然这不是必须的，但是这样对项目整体质量的提高很有好处。 在GIT使用中

We have a subfolder that is a relative svn external (../project/subfolder). In a fresh trunk checkout it points to (...TRUNK/project/subfolder) and in a fresh branch checkout it points to (...BRANCH/branchName/project/subfolder). But if you do a switch on the project containing the subfolder, the subfolder stays pointing at TRUNK. Alternately if you do a BRANCH checkout and switch to TRUNK it stays pointing at BRANCH. Shouldn't an svn:switch update relative externals? Is there some sort of recursive svn:switch I should be running? The correct answer to the question is "yes, it should update

1.远程分支拉取项目代码 git clone [url] 2.添加已修改的文件 git add . 3.提交代码到暂存区 git commit -m "提交注释" 4.重新提交 git commit --amed 5. 可编辑注释 :i 6. 退出编辑 esc 7.结束提交 :wq 8.修改提交的注释 git commit --amed -m "新的提交注释" 9.拉取最新代码 git pull 10.提交本地代码到远程仓库 git push origin 版本名称 11.查看本地所有分支 git branch 12.查看远程所有分支 git branch -r 13.查看本地与远程所有分支 git branch -a 14.新建分支 git branch 分支名称 15.新建分支并切换到该分支 git checkout -b 分支名称 16.切换到上一个分支 git checkout - 17.合并指定分支到当前分支 git merge 分支名称 18.删除指定分支 git branch -d 分支名称 来源： https://www.cnblogs.com/qianxuebing/p/11726731.html

After branching and pushing to the remote, a git remote show origin gives the report HEAD branch (remote HEAD is ambiguous, may be one of the following): master otherbranch What does the imply? It is a critical error? remote origin Fetch URL: gituser@local.repos.cc:/home/gituser/repos/csfsconf.git Push URL: gituser@local.repos.cc:/home/gituser/repos/csfsconf.git HEAD branch (remote HEAD is ambiguous, may be one of the following): master otherbranch You can see the same warning in this blog post (master)jj@im-jj:~/demo$ git checkout -b rc-1.0 Switched to a new branch 'rc-1.0' (rc-1.0)jj@im-jj:~

Initial Understanding HEAD "indicates the head of the current branch." so, there is only one HEAD. head refers to the most recent commit of any branch. "...the most recent commit (or "head") of a branch..." so, there are as many heads as there are branches. tip refers to the most recent commit of any branch. so, tip is synonymous with head Please correct me if I'm wrong. Also, please provide documentation on the usage of "tip". New Understanding after Reading Answer Each branch points at a commit. The head (or tip) is the commit at which a branch points. If there are ten branches then there

A commit isn't necessarily in a branch, so how do you see and manage these commits? Also, is it possible to look at these commits from gitk? Thanks a lot! PS: just to make things clearer, here is an example: git init git commit touch toto git add toto git commit -a echo $RANDOM > toto git commit -a git checkout f798e54 #checkout initial commit echo $RANDOM > toto git commit -a #"untracked commit" gitk --all git branch git log git checkout master #back on the main branch gitk --all #untracked commit is lost? git log git branch How can I get my "untracked commit" back? This situation is called a

My team has been working in a prototype branch off of master. I now want to take that work, slice it up into different "feature branches", and merge them individually into master. I see a couple ways to do this, neither of which I really like: 1 - Create a new branch, Feature_1, off of master . Manually copy the code from the Prototype to Feature_1. This means I have to keep track of what I've copied when I go to make Feature_N and I lose history. 2 - Create a new branch, Feature_1, off of Prototype . Somehow revert the code that is not part of the first feature in Feature_1. This avoids lying

For instance, suppose I have Repository 1 and Repository 2. Repository 1 has a file /a/b/c/d . Would it be possible for me to import this file into Repository 2 as /e/f/g/h ? The reason being that I want to pull in changes from an experimental branch from a different git repository. I tried merging everything together, but there were a ton of conflicts (of every kind). Therefore, I doubt that I can merge the entire branch in, but I would like to try to bring in as much as I can. Is there any way to do what I want to do, or am I just going to have to resort to copying files directly? You can

Here are some git actions I performed. As you can see, I made a new branch, modified my files, and then committed the changes. After changing back to another branch, hoping to merge, the branch I was just working on disappeared. Does anyone know how I can recover the files from fixed_merge_branch? I'm freaking out! 1.9.2@whisperme$ git branch fixed_merge_conflict 1.9.2@whisperme$ git checkout fixed_merge_conflict M ArtworkViewController.h M ArtworkViewController.m M ArtworkViewController.xib M Classes/DFRAppDelegate.h M Classes/DFRAppDelegate.m M Classes/WorkGalleryViewController.m M Classes
