如何创建git仓库

第一步创建空目录

midkir 文件名
cd 文件名
pwd

$ mkdir learngit
$ cd learngit
$ pwd
/Users/michael/learngit

cd：进入文件指令
pwd：显示当前文件路径
midkir：创建空目录

第二步通过git init命令把这个目录变成git可以管理的仓库

$ git init
Initialized empty Git repository in /Users/michael/learngit/.git/

.git是用来跟踪git管理版本库的
git init 将当前目录变为git管理仓库

将文件添加到版本库

第一步创建文件

touch 文件名

touch readme.txt

touch：创建文件

第二步把文件添加到仓库

git add readme.txt

add：把文件添加到仓库，可以多次使用

git add file1.txt file2.txt file3.txt

第三步使用 git commit命令把文件提交到仓库

$ git commit -m "wrote a readme file"
[master (root-commit) cb926e7] wrote a readme file
 1 file changed, 2 insertions(+)
 create mode 100644 readme.txt

-m：提交这次文件的说明

用git status查看当前仓库状态

$ git status

输出结果

$ git status
# On branch master
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#    modified:   readme.txt
#
no changes added to commit (use "git add" and/or "git commit -a")

git diff查看修改前后的状态

$ git diff

$ git diff readme.txt 
diff --git a/readme.txt b/readme.txt
index 46d49bf..9247db6 100644
