设置打开.exe文件的方式为notepad，这是一个黑客测试
C:\> ftype exefile=notepad.exe %1 %
C:\> ftype exefile=hack.exe %* && "%1" %*
改回默认状态，直接执行exe文件
C:\> ftype exefile="%1" %*
自定义新的.mus文件，用musicEditor.exe打开
C:\> assoc .mus=musicSheetFile
C:\> ftype musicSheetFile=musicEditor.exe "%1" %*
You can obtain Vim for the first time with:
git clone https://github.com/vim/vim.git
And, if you don't have local changes, update to the latest version with:
cd vim
git pull
If you made some changes, e.g. to a makefile, you can keep them and merge with the latest version with:
git stash
git pull
git stash pop
If you have local changes you may need to merge. If you are sure you can discard local changes (e.g. if you were just trying a patch), you can use:
git fetch --all
git reset --hard origin/master
提交，与修改最后一次提交
$ git commit -m 'initial commit'
$ git add forgotten_file
$ git commit --amend
回退到某一版本,并推送之仓库
git reset --hard 0d1d7fc32
git push origin HEAD --force
提交，接着撤销(undo)这次提交
$ git commit -m 'xxx'
$ git reset --soft HEAD^
保存git密码，不用每次输入git账号密码
$ git config credential.helper store #保存git密码
$ git config --global credential.helper 'cache --timeout 7200' #缓存密码2小时
switch and delete branch by using
$ git checkout gh-pages
Switched to branch 'gh-pages'
$ git branch --delete master # delete a branch in local
$ git push origin --delete master # delete a remote branch master, which is easier to remember than git push origin :<branchName>

春天，十个海子全部复活
在光明的景色中
嘲笑这一个野蛮而悲伤的海子
你这么长久的沉睡究竟为了什么
----海子
我细数它们坠落谷底，寂然化为流萤
轻轻飘过我们星光花影的足踝
----杨牧
这是逝者之歌，浮沉在
简单动人的传说里
作为谣言的伴奏——
有一支号角 城堡里吹
展翅的神是浪迹的神
----杨牧
我手扶着庄稼的手呵
也抚摸着晴空的门
我斜靠着大海的身体
也斜靠着平原上河流滚滚的乡村
你的头颅正在高地奥蓝地转侧
你的中国人正在葵花上手编着芦苇成婚
----骆一禾
- 往事啊，你背叛了结局
- 死亡是似曾相识的艺术
- 翻掌之间，永恒与往事互换
----诗阳
风，把一只又一只鸟儿
掷向天空的尽头
----吉首大学 胡建文
----原筱菲
不要说遥远
其实我已在你的掌心里
并且日渐透明
宁静无比
我的水滴
是翩飞的水鸟
绕过你手指的森林
栖落在你的指尖
你也把蓊郁的绿色
投影在我的水面
让我的心海不再空旷
握紧我吗
覆盖我吗
让我梦的水滴渗入你的根须吗
不要张开
不要让清澈的水
苦涩着从你的指缝滴尽
叶子不要为季节飘落
不要让虔诚的鸟儿追逐得
太久 太远
其实有时我不想飞
我想穿行在你影子里的
做一只悠闲的小鱼
----星球《星球暮歌》
黑夜的翅膀曾经触摸，
人类最初山岩上牧羊人竹青色的笛子，
和羊子般在夜晚甜蜜吟唱的金色嗓音，
然后在大理石神殿的山墙上，
被悲剧性的梦幻缠绕，
在伦敦和巴黎命运般的海峡两端，
被之后多少个世代因遥远而起的重量压弯。
于是我火山般沉醉毁灭之美的爱情，
从第一天起便是一座荒废掉的码头，
没有一根手指之河的流淌触摸使它平静，
没有一只带着信风的轻舟驻留使它生辉。
黑夜的翅膀，风中痛苦扇动，
我们一页页翻过人类的日子，
在一束芦花丛中，
遥望江上明月，
怀想遥远阁楼上的美丽女人。
只有她们，
犹如我们曾经自由飞翔的古老岁月中，
一双幽幽的眼睛，
与我们寂寞相依。
