###2.4、Git常用方法###

####git删除文件 git rm "文件名" git commit -m "删除文件" git push origin master ####git创建分支 git branche gh-pages ####git切换分支 git checkout gh-pages ####git push 403错误解决 [root@cloud .git]# git push origin master Xlib: extension "RANDR" missing on display "localhost:11.0". error: The requested URL returned error: 403 while accessing https://[email protected]/Data-Scientist/data-scientist.github.com.git/info/refs

[root@cloud .git]# git remote set-url origin ssh://[email protected]/Data-Scientist/data-scientist.github.com.git
[root@cloud .git]# git push origin master

####git为项目添加远程仓库分支 例子1：git remote add apacheCloudStack https://github.com/apache/cloudstack.git 例子2：git remote add upstream https://github.com/apache/cloudstack.git ####git将远程分支同步到本地库 例子1：git remote -v 本地仓库的远程分支情况 例子2：git fetch apacheCloudStack //后面的名字是远程分支的别名 ####git合并fetch下来的分支代码 例子1: git merge apacheCloudStack/master ####git将合并的后的代码推送到远程仓库 例子1: git push origin master ###2.5 Knitr 安装 1、打开Rstudio 2、在console中输入install.packages("knitr"); 3、运行KnitPost.R脚本 4、KnitPost("_drafts/heidsoft_testRmd.Rmd") 执行后在项目的根目录下生成heidsoft_testRmd.md文件 5、rake post title="heidsoft_testRmd" 6、cp heidsoft_testRmd.md ./_posts/xxxxxx_heidsoft_testRmd.md
