最近使用Octopress进行rake deploy时，控制台一直提示一堆如下警告信息：

The file will have its original line endings in your working directory. warning: LF will be replaced by CRLF in Gemfile.
The file will have its original line endings in your working directory. warning: LF will be replaced by CRLF in Gemfile.lock.
The file will have its original line endings in your working directory. warning: LF will be replaced by CRLF in README.

每次提交都要面对如此多的警告，确实忧伤。好吧，赶紧求助谷歌爸爸。Stackoverflow真是个好地方，不仅解释了为什么会有类似警告，还提供了解决的办法，这可谓VIP一条龙服务啊。

In Unix systems the end of a line is represented with a line feed (LF). In windows a line is represented with a carriage return (CR) and a line feed (LF) thus (CRLF). when you get code from git that was uploaded from a unix system they will only have a LF. It’s nothing to worry about.

原来是因为Windows和Linux在处理文本换行的差异引起的，在Windows中一行的结束符由carriage return(CR) + line feed(LF)组成，也就是CRLF；在Linux中没有CR，只有LF。大家都知道Git和Linux都是Linus Torvalds写的，理所当然Git服务端也运行在Linux系统上，当我们提交本地文件到远程仓库，Windows下的换行规则就要替换成Linux下的换行规则，也就有了上述警告。
所以呢，这类警告是完全不会影响Git的正常使用。但是，所谓眼不见心不烦啊，能不能让Git不显示这类警告呢。答案是，当然可以，而且方法也很简单，改下Git的配置文件即可。
打开Git Bash。

$ vi /etc/gitconfig

在[core]下将autocrlf = true更改为autocrlf = false。

[core]
        symlinks = false
        autocrlf = false
[color]
        diff = auto
        status = auto
        branch = auto
        interactive = true
[pack]
        packSizeLimit = 2g
[help]
        format = html
[http]
        sslCAinfo = /bin/cu
[sendemail]
        smtpserver = /bin/m

[diff "astextplain"]
        textconv = astextpl
[rebase]
        autosquash = true

再次rake deploy可以发现，整个世界都清净了。
