關於git和github的介紹，我這邊不多說。

使用在windows下使用git，需要配置環境變量，也可以使用git自帶的終端工具。，打開git bash

[email protected] MINGW64 ~ (master)
$ cd c:/laoni

[email protected]-TPPLHIB MINGW64 /c/laoni
$ dir
AutomatedMonitor  bak  Mr.blue  PycharmProjects

[email protected]-TPPLHIB MINGW64 /c/laoni
$ cd PycharmProjects
 
/

界面和linux的終端相識，首先需要進行初始化，也就是配置個人信息：

使用git help可以查看git相關命令，也可以通過git help command指定命令查詢。

$ 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 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     Use binary search to find the commit 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     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.

使用git config --global user.name "XXX" 和git config --global user.email "[email protected]"可以添加用戶名和郵箱，

使用 git config --unset --global user.name 可以取消用戶名配置，

使用 git config --list 查看所有可用的配置信息。

$ git config --global user.name ‘LaoNiNi‘

git區分工作區和版本庫

對於項目更目錄github_test目錄來說，這就是工作區。

使用 git init 命令進行初始化，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

[email protected] MINGW64 /c/laoni/PycharmProjects/github_test
$ git init
Initialized empty Git repository in C:/laoni/PycharmProjects/github_test/.git/

PS：如果對git不熟悉的話，建議不要對。git目錄下的文件進行修改。

使用git status查看當前git狀態，Untracked files（未監視的文件，未被跟蹤文件）也就是沒有存到暫存區（上面截圖的版本庫下的index部分）的文件，使用git add index.html 把文件添加到暫存區。

[email protected] 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)

[email protected]-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)

[email protected] MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git add index.html

[email protected] 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文件添加到暫存區後，需要把文件從暫存區添加到branch master分支上，一般一個項目會有個主分支（一般叫master），使用git commit提交，會提示說明下這次的提交註釋，再用git status查看，提示在當前主分支，沒有需要commit的文件，工作區很幹凈。

[email protected] MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git commit
[master (root-commit) 04c94a8] 添加一個文件index.html
 1 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

實際上不管是暫存區還是分支上的文件，都存儲在objects裏面，暫存區和分支上的文件只是一個指向，目錄樹，有點像windows裏的快捷方式了，這個需要理清。

git config配置，工作區和版本庫聯系。
