Git

1 Git基本配置

当安装Git后首先要做的事情是设置用户名称和email地址。这是非常重要的，因为每次Git提交都会使用该用户信息。

打开Git Bash
设置用户信息

git confifig --global user.name “itcast”
git confifig --global user.email “hello@itcast.cn”

查看配置信息

git confifig --global user.name
git confifig --global user.email

2 创建本地仓库

要使用Git对我们的代码进行版本控制，首先需要获得本地仓库：

1）在电脑的任意位置创建一个空目录（例如test）作为我们的本地Git仓库。

2）进入这个目录中，点击右键打开Git bash窗口。

3）执行命令git init。

4）如果创建成功后可在文件夹下看到隐藏的.git目录。

git init

3 基础git操作命令

77339@LAPTOP-59ARH7U0 MINGW64 ~/Desktop/test/.git (GIT_DIR!)
$ cd ..

77339@LAPTOP-59ARH7U0 MINGW64 ~/Desktop/test (master)
$ touch file.txt

77339@LAPTOP-59ARH7U0 MINGW64 ~/Desktop/test (master)
$ git status
On branch master

No commits yet

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        file.txt

nothing added to commit but untracked files present (use "git add" to track)

77339@LAPTOP-59ARH7U0 MINGW64 ~/Desktop/test (master)
$ git add .

77339@LAPTOP-59ARH7U0 MINGW64 ~/Desktop/test (master)
$ git status
On branch master

No commits yet

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)
        new file:   file.txt


77339@LAPTOP-59ARH7U0 MINGW64 ~/Desktop/test (master)
$ git commot -m "add file"
git: 'commot' is not a git command. See 'git --help'.

The most similar command is
        commit

77339@LAPTOP-59ARH7U0 MINGW64 ~/Desktop/test (master)
$ git commit -m "add file"
[master (root-commit) 36806c9] add file
 1 file changed, 0 insertions(+), 0 deletions(-)

4 Git远程仓库

在码云上创建仓库：

验证密钥是否配置成功：

ssh -T git@gitee.com
# 添加远程仓库
git remote add <远端名称> <仓库路径>
# 查看远程仓库
git remote
# 推送到远程仓库
git push [-f] [--set-upstream] [远端名称 [本地分支名][:远端分支名] ]

5 IDEA使用Git

5.1 配置Git

5.2 初始化本地仓库

配置.gitignore文件：

# IntelliJ project files
.idea
*.iml
out
gen
/.apt_generated/
/.classpath
/.factorypath
/.project
/.settings/
/.springBeans
/target/
/.gitignore
/user-profile-analysis.iml
/.idea
/README.md
.DS_Store
