终端使用中遇到的问题
文件出现 ^M 问题
^M 是回车符，他是源于 DOS/Windows 的，但是在 Unix 的系统中这样的符号在执行的时候会报错，在使用 vim 查看文件的时候会直接看到^M 而不是换行。
想替换掉^M，换成\r或者\n, 千万不要直接打上符号^M 进行替换，^M 这个符号要使用 ctrl+v & ctrl+m 生成，在 vim 中使用
:%s/^M/\r/g
进行替换所有回车符。
Git SVN Issue
使用 git svn 的时候报一下错误：

- 解决方法：
sudo mkdir /Library/Perl/5.18/auto
sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/SVN /Library/Perl/5.18/darwin-thread-multi-2level
sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/auto/SVN /Library/Perl/5.18/auto/
