Git简单使用

1.初始化一个git项目：

git init

2.添加一个新文件，执行git status

PS D:gittest> git status
On branch master

Initial commit

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

        test.py

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

提醒将新建文件git add
3. git add test.py，然后git status

PS D:gittest> git status
On branch master

Initial commit

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

        new file:   test.py

快照已经生成，提醒提交
4.删除快照git rm –cached test.py,然后git status

PS D:gittest> git status
On branch master

Initial commit

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

        test.py

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

5.回到步骤3的最终状态，修改test.py,然后git status

PS D:gittest> git status
On branch master

Initial commit

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

        new file:   test.py

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:   test.py

Changes not staged for commit说明文件已经修改，如果此时提交，提交内容为上次git add的文件，新修改内容没提交；可以通过git add再次更新快照，或者通过git checkout覆盖这次的修改。

• 删除本地旧分支，拉取新分支

#!/bin/bash
set -e 

cd /project/
git pull
git fetch ori --prune
git branch -r|sed 's/ori///g'|grep -v HEAD > $(dirname "$0")/version 
#显示所有分支，并去掉ori/前缀，过滤掉HEAD分支，并写到脚本同级目录下的version文件中
