> git init

Initialized empty Git repository in /.git/

Success!

$ git status

# On branch master
#
# Initial commit
#
nothing to commit (create/copy files and use "git add" to track)

Success!

当创建一个文件：octocat.txt 后

$ git status

# On branch master
#
# Initial commit
#
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# octocat.txt
nothing added to commit but untracked files present (use "git add" to track)

现在要把这个文件加入到git的准备区域（staging area）：

$ git add octocat.txt

$ git status

$ git commit -m "Add cute octocat story"

[master (root-commit) 20b5ccd] Add cute octocat story
1 file changed, 1 insertion(+)
create mode 100644 octocat.txt

现在目录底下又添加了多个txt文件：

$ git add '*.txt'

$ git commit -m 'Add all the octocat txt files'

[master 3852b4d] Add all the octocat txt files
4 files changed, 4 insertions(+)
create mode 100644 blue_octocat.txt
create mode 100644 octofamily/baby_octocat.txt
create mode 100644 octofamily/momma_octocat.txt
create mode 100644 red_octocat.txt

可以查看commit记录：

$ git log

Add all the octocat txt files

commit b652edfd888cd3d5e7fcb857d0dabc5a0fcb5e28
Author: Try Git <try_git@github.com>

Added cute octocat story

现在在Github有一个repository：https://github.com/try-git/try_git.git

现在要配置，把这个地址作为远程的repository

$ git remote add origin https://github.com/try-git/try_git.git

现在远程的repository名叫做origin，默认本地的分支叫做master，-u是让git记住参数，下一次就可以直接git push

$ git push -u origin master

Branch master set up to track remote branch master from origin.

从github上下载到本地：

$ git pull origin master

现在有一些变化，可以用git diff查看变化，HEAD表示最近一次commit

$ git diff HEAD

还可以用diff来查看已经被staged（即未被commit）的文件

所以先添加一个文件：

$ git add octofamily/octodog.txt

$ git diff --staged

可以用git reset来unstage一个staged的文件：

$ git reset octofamily/octodog.txt

可以用git checkout -- <target> 回到最后一次commit <target>

$ git checkout -- octocat.txt

创立一个新的branch：

$ git branch clean_up

切换到<branch>: git checkout <branch>

$ git checkout clean_up

Switched to branch 'clean_up'

用git rm移除所有硬盘中的文件和staged的文件

$ git rm '*.txt'

rm 'blue_octocat.txt'
rm 'octocat.txt'
rm 'octofamily/baby_octocat.txt'
rm 'octofamily/momma_octocat.txt'
rm 'red_octocat.txt'

$ git commit -m "Remove all the cats"

[clean_up 63540fe] Remove all the cats

delete mode 100644 octocat.txt
delete mode 100644 octofamily/baby_octocat.txt
delete mode 100644 octofamily/momma_octocat.txt
delete mode 100644 red_octocat.txt

$ git checkout master

合并clean_up branch：

$ git merge clean_up

可以用git branch -d <branch name> 来删除某个branch

$ git branch -d clean_up

Deleted branch clean_up (was ec6888b).

$ git push
