git config配置，工作区和版本库联系。
关于git和github的介绍，我这边不多说。使用在windows下使用git，需要配置环境变量，也可以使用git自带的终端工具。https://images2015.cnblogs.com/blog/947742/201705/947742-20170530100828571-2046526804.png，打开git bash
laoni@DESKTOP-TPPLHIB MINGW64 ~ (master)
$ cd c:
/laoni
laoni@DESKTOP
-TPPLHIB MINGW64 /c/laoni
$
dir
AutomatedMonitorbakMr.bluePycharmProjects
laoni@DESKTOP
-TPPLHIB MINGW64 /c/laoni
$ cd PycharmProjects
/
界面和linux的终端相识，首先需要进行初始化，也就是配置个人信息：
使用git help可以查看git相关命令，也可以通过git help command指定命令查询。

$ git help
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 indexmv 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 Use binary search to
find the commit that introduced a buggrep 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 Reapply commits on top of another base tip
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.
git help 使用git config --global user.name "XXX" 和git config --global user.email "XXX@XX.com"可以添加用户名和邮箱，
使用 git config --unset --global user.name 可以取消用户名配置，
使用 git config --list 查看所有可用的配置信息。

git config git区分工作区和版本库
https://images2015.cnblogs.com/blog/947742/201705/947742-20170530102202508-1551865342.png
对于项目根目录github_test目录来说，这就是工作区。
使用 git init 命令进行初始化，之前的config配置，需要初始化才能生效，config配置信息存在.git/config文件
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test
$ git init
Initialized empty Git repository in C:/laoni/PycharmProjects/github_test/.git/
PS：如果对git不熟悉的话，建议不要对。git目录下的文件进行修改。
使用git status查看当前git状态，Untracked files（未监视的文件，未被跟踪文件）也就是没有存到暂存区（上面截图的版本库下的index部分）的文件，使用git add index.html 把文件添加到暂存区。
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git status
On branch master
Initial commit
Untracked files:
(use
"git add <file>..." to include in what will be committed)
index.html
nothing added to commit but untracked files present (use
"git add" to track)
laoni@DESKTOP
-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git add index.html
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git status
On branch master
Initial commit
Changes to be committed:
(use "git rm --cached <file>..." to unstage)
new file: index.html
把index.html文件添加到暂存区后，需要把文件从暂存区添加到branch master分支上，一般一个项目会有个主分支（一般叫master），使用git commit提交，会提示说明下这次的提交注释，再用git status查看，提示在当前主分支，没有需要commit的文件，工作区很干净。
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git commit
[master (root
-commit) 04c94a8] 添加一个文件index.html1 file changed, 0 insertions(+), 0 deletions(-) create mode
100644 index.html
laoni
@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git status
On branch master
nothing to commit, working tree clean
实际上不管是暂存区还是分支上的文件，都存储在objects里面，暂存区和分支上的文件只是一个指向，目录树，有点像windows里的快捷方式了，这个需要理清。
