github 常用指令

基礎的：

生patch：

 git diff  branchname --cached > patch

Push changes from your commit into your branch :

$ git push origin [name_of_your_remote]

刪除遠端 branch:

git push origin :your_branch

刪除本地branch:

git branch -d yourbranch

update remote branch:

2 ,从远程获取最新版本到本地

$ git fetch origin master
From https://github.com/com360/android-app
 * branch            master     -> FETCH_HEAD
su@SUCHANGLI /e/eoe_client/android-app (master)





$ git fetch origin master 这句的意思是：从远程的origin仓库的master分支下载代码到本地的origin master
3. 比较本地的仓库和远程参考的区别


1
2


$ git log -p master.. origin/master
su@SUCHANGLI /e/eoe_client/android-app (master)





因为我的本地仓库和远程仓库代码相同所以没有其他任何信息
4. 把远程下载下来的代码合并到本地仓库，远程的和本地的合并

$ git merge origin/master
Already up-to-date.
su@SUCHANGLI /e/eoe_client/android-app (master)

加patch:


今天要打包最新的三個 commit 的話

    git format-patch -3

此時 git 便會幫你產生3個類似下列的檔案

0001-First.patch

0002-Second.patch

0003-Third.patch



2.那如果要套用別人的patch 也相當簡單

    git am 0001-First.patch 

就將 patch apply 上去了

================================

刪除錯誤提交commit:

方法: 

    git reset --hard 

    git push origin HEAD --force

Git patch 合併有衝突的話：

ubuntu build kernel

看這個：

安裝cmake與其相關套件東東

ubuntu 14.04: 

apt-get install cmake flex libpciaccess-dev bison libx11-dev libxext-dev libxml2-dev libvdpau-dev

apt-get install build-essential -y

apt-get install doxygen

ubuntu修改grub開機時間

here:
/etc/default/grub

after modified should be updated:

update-grub

xeyes X11 connection rejected because of wrong authentication. Error: Can't open display: localhost:11.0

發現X11 connection有問題，原來是我變成"su"之後執行指令就產生以下訊息：
xeyes X11 connection rejected because of wrong authentication. Error: Can't open display: localhost:11.0


解法：

An easier solution follow as:
1.- ssh user@host

2.- $ sudo su

3.- # xauth merge /home/user/.Xauthority

centos apache server python 網頁

在 /etc/httpd/conf/httpd.conf

寫 AddHandler cgi-script .cgi .py

service httpd restart

chmod 755 /var/www/cgi-bin/test.py

ＯＫ～
