一.下载安装Git
查看电脑是否安装git,打开终端,输入git,回车如果输出如下,则代表已安装了git
- $ git
- usage: git [--version] [--help] [-C <path>] [-c name=value]
- [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
- [-p | --paginate | --no-pager] [--no-replace-objects] [--bare]
- [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
- <command> [<args>]
-
- These are common Git commands used in various situations:
-
- start a working area (see also: git help tutorial)
- clone Clone a repository into a new directory
- init Create an empty Git repository or reinitialize an existing one
-
- work on the current change (see also: git help everyday)
- add Add file contents to the index
- mv Move or rename a file, a directory, or a symlink
- reset Reset current HEAD to the specified state
- rm Remove files from the working tree and from the index
-
- examine the history and state (see also: git help revisions)
- bisect Find by binary search the change that introduced a bug
- grep Print lines matching a pattern
- log Show commit logs
- show Show various types of objects
- status Show the working tree status
-
- grow, mark and tweak your common history
- branch List, create, or delete branches
- checkout Switch branches or restore working tree files
- commit Record changes to the repository
- diff Show changes between commits, commit and working tree, etc
- merge Join two or more development histories together
- rebase Forward-port local commits to the updated upstream head
- tag Create, list, delete or verify a tag object signed with GPG
-
- collaborate (see also: git help workflows)
- fetch Download objects and refs from another repository
- pull Fetch from and integrate with another repository or a local branch
- push Update remote refs along with associated objects
-
- ‘git help -a‘ and ‘git help -g‘ list available subcommands and some
- concept guides. See ‘git help <command>‘ or ‘git help <concept>‘
- to read about a specific subcommand or concept.

如果未安装,则会输出:
- $ git
- The program ‘git‘ is currently not installed. You can install it by typing:
- sudo apt-get install git
按照提示输入:sudo apt-get install git即可安装!!或者到此处下载:
git下载, pkg包下载完成,双击安装。
输入命令:git --version 可查看当前git版本
- $ git --version
- git version 2.5.4 (Apple Git-61)
- macdeMacBook-Pro:~ Artron_LQQ$
当然,网上也有一些安装git的途径,可自行学习...
二.安装后需要一些配置
配置用户名和邮箱:
- $ 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,如果设置单个项目的用户,可cd到项目根目录下,执行如下命令:
- $ 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他的一些信息
- $ 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.建立本地git仓库
1. cd到你的项目目录
- $ cd /Users/mac/Desktop/GitTest
2. 然后,输入git命令:
输出如下:
- $ git init
- Initialized empty Git repository in /Users/mac/Desktop/GitTest/.git/
创建了一个空的本地仓库.
3.将项目的所有文件添加到缓存中:
git add . (注意,后面有个点)表示添加目录下所有文件到缓存库,如果只添加某个文件,只需把 . 换成你要添加的文件名即可;
4.将缓存中的文件Commit到git库
git commit -m "添加你的注释,一般是一些更改信息"
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.xcodeproj/project.pbxproj
- create mode 100644 GitTest.xcodeproj/project.xcworkspace/contents.xcworkspacedata
- create mode 100644 GitTest.xcodeproj/project.xcworkspace/xcuserdata/Artron_LQQ.xcuserdatad/UserInterfaceState.xcuserstate
- create mode 100644 GitTest.xcodeproj/xcuserdata/Artron_LQQ.xcuserdatad/xcschemes/GitTest.xcscheme
- create mode 100644 GitTest.xcodeproj/xcuserdata/Artron_LQQ.xcuserdatad/xcschemes/xcschememanagement.plist
- create mode 100644 GitTest/AppDelegate.h
- create mode 100644 GitTest/AppDelegate.m
- create mode 100644 GitTest/Assets.xcassets/AppIcon.appiconset/Contents.json
- create mode 100644 GitTest/Base.lproj/LaunchScreen.storyboard
- create mode 100644 GitTest/Base.lproj/Main.storyboard
- create mode 100644 GitTest/Info.plist
- create mode 100644 GitTest/ViewController.h
- create mode 100644 GitTest/ViewController.m
- 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 ,但是这样会进入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.xcodeproj/project.pbxproj
- # modified: LQQCircleShowImage/TableViewCell.m
- #
-
- "~/Desktop/LQQCircleShowImage/.git/COMMIT_EDITMSG" 8L, 292C
在这里可以输入更改信息,也可以不输入,然后 按住 shift + : ,输入wq 即可保存信息并退出vim编辑器;
四,建立远程库
在一些代码托管平台创建项目,例如github或者开源中国社区,这里已开源中国社区为例;
创建项目后,会生成一个HTTPS链接,如下:
五,将本地的库链接到远程库
终端中输入: git remote add origin HTTPS链接
- $ git remote add origin https:
六.上传代码到远程库,上传之前最好先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:
- * 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:
- 5e2dda1..537ecfe master -> master
即将代码成功提交到远程库!!!
接着到你的远程库查看,提交前:
提交成功后:
注意:操作的时候,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!!
如果在push的时候有如下输出:
- $ git push -u origin master
- To https:
- ! [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,需要先pull一下,即执行一次:git pull origin master
然后再执行:git push origin master
分支管理
新建分支
查看分支
输出:
*代表当前所在的分支
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
提交改动到当前分支
- $ git add .
- $ git commit -a
可使用git status查看提交状态
接着切回主分支
输出:
- Switched to branch ‘master‘
将新分支提交的改动合并到主分支上
输出:
- Updating cc73a48..93a1347
- Fast-forward
- GitTest.xcodeproj/project.pbxproj | 9 +++++++++
- .../UserInterfaceState.xcuserstate | Bin 0 -> 7518 bytes
- GitTest/test.h | 13 +++++++++++++
- GitTest/test.m | 13 +++++++++++++
- 4 files changed, 35 insertions(+)
- create mode 100644 GitTest.xcodeproj/project.xcworkspace/xcuserdata/Artron_LQQ.xcuserdatad/UserInterfaceState.xcuserstate
- 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
如果合并后产生冲突,可输入以下指令查看冲突:
修改之后,再次提交即可;
接下来,就可以push代码了:
- $ git push -u origin master
这时可能需要你输入你的github用户名和密码,按照提示输入即可;
删除分支
- $ git branch -D newbranch
输出
- Deleted branch newbranch (was 93a1347).
