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. macdeMacBook-Pro:~ Artron_LQQ$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$
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 protected]"
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 protected]"
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/GitTest2. 然后,输入git命令:
$ git init
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 .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:
https://git.oschina.net/liuqiqiang/gitTest.git
终端中输入: git remote add origin HTTPS链接
$ git remote add origin https://git.oschina.net/liuqiqiang/gitTest.git
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
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
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://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,需要先pull一下,即执行一次:git pull origin master
然后再执行:git push origin master
以上只是初级的最简单的指令操作,其他复杂的操作可自行摸索...
