1、首先须要下载gitgit

　　查看电脑是否安装git,打开终端，输入git,回车若是输出以下,则表明已安装了gitgithub

若是未安装,则会输出:json

按照提示输入:sudo apt-get install git便可安装!!或者到此处下载:git下载, pkg包下载完成，双击安装。vim

输入命令:git --version 可查看当前git版本xcode

二.安装后须要一些配置缓存

配置用户名和邮箱:app

$ git config --global user.name "Your Name"  
$ git config --global user.email "email@example.com"

使用 --global 修饰后设置的全局的用户,若是设置单个项目的用户,可cd到项目根目录下,执行以下命令:编辑器

$ git config user.name "Your Name"  
$ git config user.email "email@example.com"

使用命令:git config --list 可查看当前用户信息以及其余的一些信息post

$ git config --list  
core.excludesfile=/Users/mac/.gitignore_global  
difftool.sourcetree.cmd=opendiff "$LOCAL" "$REMOTE"  
difftool.sourcetree.path=  
mergetool.sourcetree.cmd=/Applications/SourceTree.app/Contents/Resources/opendiff-w.sh "$LOCAL" "$REMOTE" -ancestor "$BASE" -merge "$MERGED"  
mergetool.sourcetree.trustexitcode=true  
http.postbuffer=524288000  
https.postbuffer=524288000  
user.email=你的邮箱@qq.com  
user.name=你的用户名  
macdeMacBook-Pro:~ Artron_LQQ$

三.创建本地git仓库fetch

1. cd到你的项目目录

$ cd /Users/cjk/Desktop/myShop

2. 而后,输入git命令:

$ git init

输出以下:

$ git init  
Initialized empty Git repository in /Users/cjk/Desktop/GitTest/.git/

建立了一个空的本地仓库.

3.将项目的全部文件添加到缓存中:

$ git add .

git add . (注意,后面有个点)表示添加目录下全部文件到缓存库,若是只添加某个文件,只需把 . 换成你要添加的文件名便可;

4.将缓存中的文件Commit到git库

git commit -m "添加你的注释,通常是一些更改信息"

下面是第一次提交时的输出:

$ git commit -m "添加项目"
[master (root-commit) 3102a38] 添加项目
 18 files changed, 1085 insertions(+)

 create mode 100644 GitTest/main.m
 create mode 100644 GitTestTests/GitTestTests.m
 create mode 100644 GitTestTests/Info.plist
 create mode 100644 GitTestUITests/GitTestUITests.m
 create mode 100644 GitTestUITests/Info.plist

或者不添加注释 git commit ,可是这样会进入vim(vi)编辑器

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
# On branch master
# Changes to be committed:

#       modified:   LQQCircleShowImage/TableViewCell.m

~

~                                                                               
~                                                                               
~                                                                               
~                                                                               
~                                                                               
~                                                                               
~                                                                               
~                                                                               
~                                                                               
~                                                                               
~                                                                               
~                                                                               
"~/Desktop/LQQCircleShowImage/.git/COMMIT_EDITMSG" 8L, 292C

在这里能够输入更改信息,也能够不输入,而后按住 shift + : ,输入wq 便可保存信息并退出vim编辑器;

四,创建远程库

在一些代码托管平台建立项目,例如github或者开源中国社区,这里已开源中国社区为例;

建立项目后,会生成一个HTTPS连接,以下:

https://git.oschina.net/liuqiqiang/gitTest.git

五,将本地的库连接到远

终端中输入: git remote add origin HTTPS连接

$ git remote add origin https://git.oschina.net/liuqiqiang/gitTest.git

六.上传代码到远程库,上传以前最好先Pull一下,再执行命令: git pull origin master

输出:

$ git pull origin master
warning: no common commits
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
From https://git.oschina.net/liuqiqiang/gitTest
 * branch            master     -> FETCH_HEAD
 * [new branch]      master     -> origin/master
Merge made by the 'recursive' strategy.
 README.md | 1 +
 1 file changed, 1 insertion(+)
 create mode 100644 README.md

即pull成功,

七.接着执行:git push origin master

完成后输出:

$ git push origin master
Counting objects: 34, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (29/29), done.
Writing objects: 100% (34/34), 15.63 KiB | 0 bytes/s, done.
Total 34 (delta 3), reused 0 (delta 0)
To https://git.oschina.net/liuqiqiang/gitTest.git
   5e2dda1..537ecfe  master -> master

即将代码成功提交到远程库!!!

注：若是pull以后出现 “ refusing to merge unrelated histories ”这句，就证实你合并pull两个不一样的项目

出现的问题如何去解决fatal: refusing to merge unrelated histories

我在Github新建一个仓库，写了License，而后把本地一个写了好久仓库上传。

先pull，由于两个仓库不一样，发现refusing to merge unrelated histories，没法pull

由于他们是两个不一样的项目，要把两个不一样的项目合并，git须要添加一句代码，在git pull，这句代码是在git 2.9.2版本发生的，最新的版本须要添加--allow-unrelated-histories

假如咱们的源是origin，分支是master，那么咱们须要这样写git pull origin master --allow-unrelated-histories须要知道，咱们的源能够是本地的路径

接着到你的远程库查看,提交前:

提交成功后：

注意:操做的时候,指令不要输错了!!!!

下面这个是输错了 orgin的输出:

git pull orgin master
fatal: 'orgin' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

正确的应该是origin!!

若是在push的时候有以下输出:

$ git push -u origin master
To https://git.oschina.net/liuqiqiang/LQQCircleShowImage.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://git.oschina.net/liuqiqiang/LQQCircleShowImage.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

看提示可知道,须要先pull一下,即执行一次:git pull origin master

而后再执行:git push origin master

分支管理

新建分支

$ git branch newbranch

查看分支

$ git branch

输出:

* master
  newbranch

*表明当前所在的分支

切换分支

$ git checkout new branch

输出

Switched to branch 'newbranch'

切换后可用git branch查看是否切换到当前分支

master
* newbranch

提交改动到当前分支

$ git add .
$ git commit -a

可以使用git status查看提交状态

接着切回主分支

$ git checkout master

输出:

Switched to branch 'master'

将新分支提交的改动合并到主分支上

$ git merge newbranch

输出:

Updating cc73a48..93a1347

 create mode 100644 GitTest/test.h
 create mode 100644 GitTest/test.m

这里我提交了两个文件,即:test.h和test.m

若是合并后产生冲突,可输入如下指令查看冲突:

$ git diff

修改以后,再次提交便可;

接下来,就能够push代码了:

$ git push -u origin master

这时可能须要你输入你的github用户名和密码,按照提示输入便可;

删除分支

$ git branch -D newbranch

输出

Deleted branch newbranch (was 93a1347).

以上就是最简单的github操做了，也是在网上看着学的，注意在实际操做中多加练习，代码这东西，刚开始桥的多了也就记下了！
