Git是一個版本控制工具Github是一個用git做版本控制的專案託管平臺。Git和GitHub一直以為是兩個差不多的東西，但是具體是哪些差異還真沒去了解過，現在Git也託管到了GitHub，都怪自己不求甚解以致有此一說。我有GitHub的賬號但是提交程式碼到遠端伺服器總是提示驗證不通過，從OSC中註冊GIT@OSC才發現之前通過Eclipse生成的RSA加密方式應該是不對的，這篇文章先從Git入手，稍後會將GitHub的SSHkey進行研究說明。

1.下載Git
http://git-scm.com/downloads

2.Git託管到GitHub證據
看過這個介面的都知道是GitHub專案管理介面：

3.Git安裝
採用預設安裝，直接點選下一步直到完成。

4.配置環境變數
在path變數中編輯新增如下變數：

;C:\Program Files\Git\bin;C:\Program Files\Git\mingw64\libexec\git-core
新增完成後，測試git是否可用，cmd進入命令視窗操作，如看到如下所示資訊說明Git配置成功。

4.Git@OSC操作手冊
安裝設定 git
下載最新版本的git

http://git-scm.com/downloads
當你安裝完成git的時候，你需要簡單的配置一下，開啟終端：

使用者名稱
第一步，你需要告訴git你的名字，這個名字會出現在你的提交記錄中。

git config --global user.name "你的名字"
Email
然後是你的Email，同樣，這個Email也會出現在你的提交記錄中，請儘量保持此Email和您的Git@OSC的註冊Email一致。

git config --global user.email "你的Email"
Clone 和 Push
Clone 專案

git clone http://git.oschina.net/xxxxxx/xxxxxx.git
建立特性分支

git checkout -b $feature_name
寫程式碼，提交變更

git commit -am "My feature is ready"
將你的提交推送到 Git@OSC

git push origin $feature_name
在提交頁面你可以檢視你的變更，例如：

http://git.oschina.net/oschina/git-osc/commit/f3dd1c5bae48fa4244e2595a39e750e5606dd9be

建立一個 pull request
你可以fork任意的公開專案，當你修改了你fork的專案，你可以向源專案提交pull request。專案的作者在審閱過程式碼後可以決定是否將此變更應用到源專案。

在GIT@OSC上使用SVN
使用教程已經整理在這裡

SSH Keys
SSH key 可以讓你在你的電腦和 Git @ OSC 之間建立安全的加密連線。

你可以按如下命令來生成sshkey

ssh-keygen -t rsa -C "[email protected]"# Creates a new ssh key using the provided email
# Generating public/private rsa key pair...
檢視你的public key，並把他新增到 Git @ OSC http://git.oschina.net/keys

cat ~/.ssh/id_rsa.pub
# ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC6eNtGpNGwstc....
新增後，在終端（Terminal）中輸入

ssh -T [email protected]
若返回

Welcome to Git@OSC, yourname! 
則證明新增成功。

Git @ OSC Flavored Markdown
Git @ OSC 的markdown基於原markdown做了一下擴充套件，具體使用如下。

You can use GFM in:
提交訊息
評論
issues
pull requests
里程碑
wiki 頁面
跟傳統的Markdown的區別
URL 自動連結
插入的URL不需要做特殊處理，會自動變成連結。
Emoji表情
支援Emoji表情，參考：Emoji cheat sheet

插入程式碼片段
可以向如下這種方式插入程式碼片段，可以在標記後面指定程式語言，如果沒有指定語言，編譯器會嘗試自動識別。

```ruby
require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html
```
將會變成

require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html
特殊的 Git@OSC 引用。
GFM 可以識別一些特殊的標記，並且支援自動補全，例如：

#123 （Issue）
!123 （Pull Request）
1234567 （提交）
:icon: （emoji 表情）
如何匯入外部的Git倉庫？
因為一些原因暫沒有開放一鍵匯入功能。
有需求的可以先按照如下步驟匯入其它地方的git倉庫（以 github 上的 impress.js 為例）：

1. 從原始地址 clone 一份 bare 倉庫：

git clone --bare  https://github.com/bartaz/impress.js.git
2. 在 GIT@OSC 上 建立一個專案

3. 以 mirror 的方式把剛才 clone 的專案 push 到 GIT@OSC 上： （如果提示輸入 git 使用者密碼，請到http://git.oschina.net/keys 新增 SSH Key）

cd impress.js.git
git push --mirror [email protected]:username/impress-js.git
這種方式的好處是：可以完整地保留原專案的所有 branch 和 tag 資訊。
提示:首次push內容量較大，推薦採用ssh方式push，傳輸更快，更穩定，如果專案較小，也可以採用http方式push。

更多匯入辦法，請點選這裡

專案組的使用
專案組可以使使用者更加方便的新增使用者到專案中

1. 建立專案組：http://git.oschina.net/teams/new

2. 新增使用者：可以設定兩種許可權，一種是使用者預設在專案中的許可權，一種是專案組管理許可權

3. 指派到專案：如果選擇開發者，那麼將會按照使用者在專案組中的預設許可權為專案新增；如果選擇管理員，那麼專案組中的所有成員將會成為專案的管理員

4. 撤銷專案：撤銷專案將會把在專案屬於專案組中的成員移除，如果成員同樣存在於此專案別的專案組中，那麼將會更新為別的專案組中的相應的專案許可權。

Tips

專案組只有專案組的成員可以訪問

專案組的名稱是全站唯一的

一個使用者存在於兩個專案組a，b中，在a中的專案許可權是管理員，在b中的專案許可權是開發者，如果專案組a，b同時指派到專案pro，那麼將專案組a從pro中移除之後，此使用者在pro中的許可權將會從管理員降為開發者。

README 規則
1. git@osc README 檔案支援多種檔案格式以及命名規則。

例如： README, README.md, README.org...

或者： README_zh.md, README_en.md...

2. 若有多個README檔案，則優先顯示檔名包含'_zh','_cn'等中文標註的README檔案。

例如同一目錄包含兩個README檔案：README_en.md README_zh.md

則顯示README為： README_zh.md

改寫歷史，去除大檔案
git filter-branch --tree-filter 'rm -f path/to/large/files' --tag-name-filter cat -- --all
git push origin --tags --force
git push origin --all --force

Git for Windows v2.7.0 Release Notes
Latest update: January 5th 2016

Introduction
These release notes describe issues specific to the Git for Windows release. The release notes covering the history of the core git commands can be foundin the Git project.

See http://git-scm.com/ for further details about Git including ports to other operating systems. Git for Windows is hosted athttps://git-for-windows.github.io/.

Known issues
Special permissions (and Windows Vista or later) are required when cloning repositories with symbolic links, therefore support for symbolic links is disabled by default. Usegit clone -c core.symlinks=true <URL> to enable it, see detailshere.
If configured to use Plink, you will have to connect with putty first and accept the host key.
Some console programs interact correctly with MinTTY only when called throughwinpty (e.g. the Python console needs to be started aswinpty python instead of justpython).
cURL uses $HOME/_netrc instead of$HOME/.netrc.
If you specify command-line options starting with a slash, POSIX-to-Windows path conversion will kick in converting e.g. "/usr/bin/bash.exe" to "C:\Program Files\Git\usr\bin\bash.exe". When that is not desired -- e.g. "--upload-pack=/opt/git/bin/git-upload-pack" or "-L/regex/" -- you need to set the environment variable MSYS_NO_PATHCONV temporarily, like so:

MSYS_NO_PATHCONV=1 git blame -L/pathconv/ msys2_path_conv.cc

Alternatively, you can double the first slash to avoid POSIX-to-Windows path conversion.

Git for Windows will not allow commits containing DOS-style truncated 8.3-format filenames ending with a tilde and digit, such asmydocu~1.txt. A workaround is to callgit config core.protectNTFS false, which is not advised. Instead, add a rule to .gitignore to ignore the file(s), or rename the file(s).
Many Windows programs (including the Windows Explorer) have problems with directory trees nested so deeply that the absolute path is longer than 260 characters. Therefore, Git for Windows refuses to check out such files by default. You can overrule this default by setting core.longPaths, e.g. git clone -c core.longPaths=true ....
Some commands are not yet supported on Windows and excluded from the installation.
As Git for Windows is shipped without Python support, all Git commands requiring Python are not yet supported; e.g.git p4.
The Quick Launch icon will only be installed for the user running setup (typically the Administrator). This is a technical restriction and will not change.
Should you encounter other problems, please search the bug tracker and the mailing list, chances are that the problem was reported already. If it has not been reported, please followour bug reporting guidelines and report the bug.

Licenses
Git is licensed under the GNU Public License version 2.

Git for Windows also contains Embedded CAcert Root Certificates. For more information please go tohttps://www.cacert.org/policy/RootDistributionLicense.php.

This package contains software from a number of other projects including Bash, zlib, curl, msmtp, tcl/tk, perl, MSys2 and a number of libraries and utilities from the GNU project, licensed under the GNU Public License. Likewise, it contains Perl which is dual licensed under the GNU Public License and the Artistic License.

Changes since Git for Windows v2.6.4 (December 14th 2015)

Bug Fixes
Git for Windows v2.6.3's installer failed to elevate privileges automatically (reported three times, making it a charm), and as a consequence Git for Windows 2.6.3 was frequentlyinstalled per-user by mistake
The bug where SHELL_PATH had spaces and that was reported multiple times has been fixed.
An additional work-around from upstream Git for SHELL_PATH containing spaces (fixingproblems with interactive rebase'sexec command has been applied.
Changes since Git for Windows v2.6.2 (October 19th 2015)
New Features
Comes with Git v2.6.3.
Enables the stack smasher to protect against buffer overflows.
Bug Fixes
Git Bash works now even when choosing Windows' default console and installing into a short path (e.g.C:\Git).

Replaces git flow with the AVH edition which is maintained actively, in surprising and disappointing contrast to Vincent Driessen's very own project.
Bug Fixes
The PATH variable is now really left alone when choosing the "Use Git from Git Bash only" option in the installer. Note that upgrading Git for Windows will call the previous version's uninstaller, which might still have that bug.
Git GUI's Registry>Create Desktop Icon now generates correct shortcuts.
The antiword utility to render Word documents for use in git diffnow works correctly.
In 64-bit installations, we no longer set a pack size limit by default.

Portable Git's README is now clearer about the need to run post-install.bat when unpacking manually.
We use thewinpty trick now to runipython interactively, too.
When the environment variable HOME is not set, we now fall back correctly to use HOMEDRIVE and HOMEPATH.
The home directory is now set correctly when running as the SYSTEM user.
The environment variable GIT_WORK_TREE may now differ in lower/upper case with the Git's idea of the current working directory.
Running git clone --dissociate ... no longer locks the pack files during the repacking phase.
Upstream cURL fixes for NTLM proxy issues ("Unknown SSL error") were backported.
The 64-bit version now includes the astextplain script it lacked by mistake.

Changes since Git-2.5.2 (September 10th 2015)
Bug fixes
The Git GUI can be launched from the Start menu again.
It now works to call git add -p -- . when there is a large number of files.

Git can now clone into a drive root, e.g.C:\.
For backwards-compatibility, redirectors are installed into /bin/bash.exe and/bin/git.exe, e.g.to support SourceTree and TortoiseGit better.
When using core.symlinks = true while cloning repositories with symbolic links pointing to directories,git status no longer shows bogus modifications.

The Git Bash learned to support several options to support running the Bash in arbitrary terminal emulators.
Bug fixes
Just like Git for Windows 1.x, pressing Shift+Tab in the Git Bash triggers tab completion.
Auto-mount the temporary directory of the current user to/tmp/ again, just like Git for Windows 1.x did (thanks to MSys1's hard-coded mount point).
Changes since Git-2.4.0(2) (May 7th 2015)
New Features
Comes with Git 2.4.1
Bug fixes
When selecting the standard Windows console window for Git Bash, a regression was fixed that triggeredan extra console window to be opened.
The password can be entered interactively again when git pushing to a HTTPS remote.
Changes since Git-2.4.0 (May 5th 2015)
Bug fixes
The .sh file association was fixed
The installer will now remove files from a previous Git for Windows versions, particularly important for 32-bit -> 64-bit upgrades
New Features
The installer now offers the choice between opening the Git Bash in a MinTTY (default) or a regular Windows console window (Git for Windows 1.x' setting).
Changes since Git-2.3.7-preview20150429
New Features
Comes with Git 2.4.0
Git for Windows now installs its configuration into a Windows-wide location: %PROGRAMDATA%\Git\config (which will be shared by libgit2-based applications with the next libgit2 version)
Bug fixes
Fixed a regression where Git Bash would not start properly on Windows XP
Tab completion works like on Linux and MacOSX (double-Tab required to show ambiguous completions)

git gui can Explore Working Copy on Windows again (thanks Markus Heidelberg).
git gui can create shortcuts again (fixes issue 425, thanks Heiko Voigt).
When git checkout cannot overwrite files because they are in use, it will offer to try again, giving the user a chance to release the file (thanks Heiko Voigt).

Thanks to Johan 't Hart, files and directories starting with a single dot (such as.git) will now be marked hidden (you can disable this setting with core.hideDotFiles=false in your config) (Issue 288).
Thanks to Thorvald Natvig, Git on Windows can simulate symbolic links by using reparse points when available. For technical reasons, this only works for symbolic links pointing to files, not directories.
A lot of work has been put into making it possible to compile Git's source code (the part written in C, of course, not the scripts) with Microsoft Visual Studio. This work is ongoing.
Thanks to Sebastian Schuberth, we only offer the (Tortoise)Plink option in the installer if the presence of Plink was detected and at least one Putty session was found..

Bugfixes
Plink errors out rather than hanging when the user needs to accept a host key first (Issue 96).
The user home directory is inferred from $HOMEDRIVE\$HOMEPATH instead of$HOME (Issue 108).
The environment setting $CYGWIN=tty is ignored (Issues 138, 248 and 251).
The ls command shows non-ASCII filenames correctly now (Issue 188).
Adds more syntax files for vi (Issue 250).

In some setups, hard-linking is not as reliable as it should be, so we have a workaround which avoids hard links in some situations (Issues 222 and 229).
git-svn sets core.autocrlf to false now, hopefully shutting up most of thegit-svn reports.
Changes since Git-1.6.2.1-preview20090322

Upgraded Tcl/Tk to 8.5.5.

Uses pthreads (faster garbage collection on multi-core machines).

Bugfixes
Renaming was made more robust (due to Explorer or some virus scanners, files could not be renamed at the first try, so we have to try multiple times).
Johannes Sixt made lots of changes to the test-suite to identify properly which tests should pass, and which ones cannot pass due to limitations of the platform.
Support PAGERs with spaces in their filename.
Quite a few changes were undone which we needed in the olden days of msysGit.
Fall back to / when HOME cannot be set to the real home directory due to locale issues (works around Issue 108 for the moment).

Git correctly passes port numbers to PuTTY's Plink
Changes since Git-1.5.4-preview20080202
New Features
Comes with official git 1.5.5.
core.autocrlf is enabled (true) by default. This means git converts to Windows line endings (CRLF) during checkout and converts to Unix line endings (LF) during commit. This is the right choice for cross-platform projects. If the conversion is not reversible, git warns the user. The installer warns about the new default before the installation starts.
The user does no longer have to "accept" the GPL but only needs to press "continue".
Installer deletes shell scripts that have been replaced by builtins. Upgrading should be safer.
Supports git svn. Note that the performance might be below your expectation.
Bugfixes
Newer ssh fixes connection failures (issue 74).

New Features
Git is included in version 1.5.3.6.
Setup displays release notes.
Bugfixes
pull/fetch/push in git-gui works. Note, there is no way forssh to ask for a passphrase or for confirmation if you connect to an unknown host. So, you must have ssh set up to work without passphrase. Either you have a key without passphrase, or you started ssh-agent. You may also consider using PuTTY by pointingGIT_SSH toplink.exe and handle your ssh keys with Pageant. In this case you should include your login name in urls. You must also connect to an unknown host once from the command line and confirm the host key, before you can use it fromgit-gui.
Changes since Git-1.5.3-preview20071027
New Features
Git is included in version 1.5.3.5.
