3. git repository usage

# yum install -y git

1). 初始化git repository

首先github建立代码仓库

### initial git

本地代码库/opt/firstapp/py_web，远程代码库地址 https://github.com/longtian001/py_web

# cd /opt/firstapp(代码库存放目录)

### def remote origin

# git remote add origin https://github.com/longtian001/py_web

### get remote repository to local

# git clone https://github.com/longtian001/py_web

### watch remote git

# git remote -v

origin  https://github.com/longtian001/py_web (fetch)

origin  https://github.com/longtian001/py_web (push)

2).所有文件初次提交远程git repository）

# cd py_web

# git add . （将改动添加到暂存区）

# git commit -m "init prog"

# git push origin master 将本地更改推送到远程master分支。

3).添加新的文件

py_web文件夹添加了新的代码文件

# git add newfile_name （将改动添加到暂存区）

# git commit -m "add new file"

# git push origin master 将本地更改推送到远程master分支。

4).修改同名文件后提交

如果在github的remote上已经有了文件，会出现错误。

此时应当先pull一下，即：

# git add .

# git commit -m "modify add flask"

# git pull origin master

然后再进行：

# git push origin master

5).删除文件

# git rm *.py -r

rm ‘hello.py‘

rm ‘hello02.py‘

# git commit -m "rm py files"

[master 9f6ea78] rm py files
