How to replace crlf with lf in a single file
提问by Charles Belov
How do I convert a single file that has crlf line returns to have lf line returns?
如何将具有 crlf 行返回的单个文件转换为具有 lf 行返回？
git is already correctly handling crlf to lf conversion automatically for files when I push them to a remote repository, but in this particular case I am not doing a push to a repository. Rather, I am uploading a file, using a file field on an HTML form, to a website that requires that the file have lf line returns. So I need to be able to convert this file individually.
当我将文件推送到远程存储库时，git 已经正确处理了文件的 crlf 到 lf 转换，但在这种特殊情况下，我没有推送到存储库。相反，我使用 HTML 表单上的文件字段将文件上传到要求文件具有 lf 行返回的网站。所以我需要能够单独转换这个文件。
My available potentially useful tools available on this computer would be git and Dreamweaver CC 2014.1. (I'm guessing Word, Wordpad and Notepad are not viable options but I'm open to being corrected.)
我在这台计算机上可用的潜在有用工具是 git 和 Dreamweaver CC 2014.1。（我猜 Word、写字板和记事本不是可行的选择，但我愿意接受纠正。）

The git installation on windows usually includes the dos2unixtool.
Windows 上的 git 安装通常包含该dos2unix工具。
dos2unix <file>
But in your case you should use .gitattributesto prevent the file from being converted on windows.
但是在您的情况下，您应该使用.gitattributes来防止文件在 Windows 上被转换。
A .gitattributesfile can look like this
一个.gitattributes文件可以是这样的
*.vcproj eol=crlf
*.sh eol=lf
From the .gitattributes documentation
Set to string value "lf"
This setting forces Git to normalize line endings to LF on checkin and prevents conversion to CRLF when the file is checked out.
设置为字符串值“lf”
此设置强制 Git 在签入时将行尾规范化为 LF，并防止在签出文件时转换为 CRLF。
Just commit the .gitattributesfile and your file will be checkout out on every system with LFline ending.
只需提交.gitattributes文件，您的文件将在每个系统上以LF行结尾签出。

To convert from Windows-style text to Unix-style text:
要将 Windows 样式的文本转换为 Unix 样式的文本：
perl -pe 's/\r$//g' < windows_file.txt > unix_file.txt
To convert from Unix-style text to Windows-style text:
要将 Unix 样式的文本转换为 Windows 样式的文本：
perl -pe 's/(?<!\r)\n/\r\n/g' < unix_file.txt > windows_file.txt
This "Unix-to-Windows" command is "safe", by which I mean that it won't add extra Carriage-Returns to a file that is already in Windows format. I hope that someone will get some use out of it.
这个“Unix-to-Windows”命令是“安全的”，我的意思是它不会向已经是 Windows 格式的文件添加额外的回车。我希望有人能从中得到一些好处。

In Notepad++ on the bottom panel on to the Right, right click on the area Windows (CR LF) and select UNIX (LF) this should replace all CRLFs with LFs
在右侧底部面板的 Notepad++ 中，右键单击区域 Windows (CR LF) 并选择 UNIX (LF) 这应该将所有 CRLF 替换为 LF

Word and wordpad are to avoid! NEVERtry to modify some code with it, they will add extra code for the file.
Word 和写字板是要避免的！永远不要尝试用它修改一些代码，他们会为文件添加额外的代码。
To convert the line end, you just use Notepad++or Scite, then you choose your end of file: Windows, Mac, Linux.
要转换行尾，您只需使用 Notepad++或Scite，然后选择文件的结尾：Windows、Mac、Linux。
Here is an example using Scite:
