将 ^M (Windows) 换行符转换为普通换行符
Vim 在每一行结尾处显示 ^M。
如何将其替换为在 Vim 中打开的文件中的正常换行符？
Vim shows ^M on every line ending.
How do I replace this with a normal line break in a file opened in Vim?

另外，还有名为 dos2unix 和 unix2dos 的开源实用程序可以完成此操作。 在 Linux 系统上，它们可能是默认安装的； 对于 Windows 系统，您可以从 http://www.bastet.com/ 等下载它们。
Alternatively, there are open-source utilities called dos2unix and unix2dos available that do this very thing. On a linux system they are probably installed by default; for a windows system you can download them from http://www.bastet.com/ amongst others.
其中 ^M 是通过同时按下 3 个键来输入的，ctrl + v + m
where ^M is typed by simultaneously pressing the 3 keys, ctrl + v + m
如果文件是在 Windows 上创建的，请使用 dos2unix 实用程序，
如果文件是在 Mac 上创建的，请使用 mac2unix 实用程序。 :)
use dos2unix utility if the file was created on windows,
use mac2unix utility if the file was created on mac. :)
使用以下命令之一：
或者
Use one of these commands:
Or
在 VIM 的命令模式下：
e ++ff=dos- 强制以dos格式打开文件。setl ff=unix- 将文件转换为unix格式。up- 仅在修改后保存文件。In command mode in VIM:
e ++ff=dos- force open file indosformat.setl ff=unix- convert file tounixformat.up- save file only when has been modified.要节省击键次数，您可以避免输入 Ctrl+VCtrl+M，方法是将其放入映射中。 只需打开一个包含 ^M 字符的文件，将其拉出，然后将其粘贴到 .vimrc 中如下所示的行中：
To save keystrokes, you can avoid typing Ctrl+VCtrl+M by placing this in a mapping. Just open a file containing a ^M character, yank it, and paste it into a line like this in your .vimrc:
这对我有用：
This worked for me:
要在 MacOS 上使用
sed，请执行以下操作：说明：此处的
$'STRING'语法适用于 bash shell。 Mac 不将\r视为特殊字符。 通过引用$''中的命令字符串，您可以告诉 shell 将\r替换为 ANSI 中指定的实际\r字符-C标准。To use
sedon MacOS, do this:Explanation: The
$'STRING'syntax here pertains to the bash shell. Macs don't treat\ras special character. By quoting the command string in$''you're telling the shell to replace\rwith the actual\rcharacter specified in the ANSI-C standard.这些建议对我来说都不起作用，因为我在使用 vim 和 eclipse 时设法获得了大量
^M换行符。 我怀疑我遇到了外部案例，但以防万一它对我所做的任何人有帮助。它解决了我的问题
None of these suggestions were working for me having managed to get a load of
^Mline breaks while working with both vim and eclipse. I suspect that I encountered an outside case but in case it helps anyone I did.And it sorted out my problem
如果您使用
Shift+6 Caps+M键入^M，它将不会接受。您需要输入
ctrl+v ctrl+m。If you type
^MusingShift+6 Caps+Mit won't accept.You need to type
ctrl+v ctrl+m.^M会产生不需要的换行符。 为了处理这个问题，我们可以使用 sed 命令，如下所示：^Mgives unwanted line breaks. To handle this we can use thesedcommand as follows:只需删除 .vimrc 中的
set binary即可！Just remove

并换行(

Where
<Ctrl-V><Ctrl-M>means type Ctrl+V then Ctrl+M.Explanation

with new line (
\r)And do it globally (not just the first occurrence on the line).
在 Linux 和 Mac OS 上，以下操作有效，
其中
^V^M表示键入 Ctrl+V，然后键入 Ctrl+M。注意：在 Windows 上，您可能需要使用
^Q而不是^V，因为默认情况下^V映射到粘贴文本.On Linux and Mac OS, the following works,
where
^V^Mmeans type Ctrl+V, then Ctrl+M.Note: on Windows you probably want to use
^Qinstead of^V, since by default^Vis mapped to paste text.在
vim中，查看文件格式 — DOS 或 Unix：:set filetype=unix:set fileformat=unix文件将被写回，不带回车符（CR、^M）。
Within
vim, look at the file format — DOS or Unix::set filetype=unix:set fileformat=unixThe file will be written back without carriage return (CR, ^M) characters.

我在 MacVim 中使用 BBEdit 创建的文件显示了一堆
^M行返回，而不是常规的行返回。 下面的字符串替换解决了这个问题：这很有趣，因为我用相同的字符替换换行符，但我想 Vim 只需要获取一个新的 \r 即可正确显示。 我有兴趣了解其工作原理的基本机制。
A file I had created with BBEdit seen in MacVim was displaying a bunch of
^Mline returns instead of regular ones. The following string replace solved the issue:It's interesting because I'm replacing line breaks with the same character, but I suppose Vim just needs to get a fresh \r to display correctly. I'd be interested to know the underlying mechanics of why this works.
首先，使用
:set ff?确定您的文件的文件格式。我猜它可能是
unix，那么问题是您的文件是使用fileformat=dos创建的，在行尾添加了“^M^J”，但使用读取flieformat=unix仅从行尾删除“^J”，保留“^M”。只需在 Vim 命令行中输入
:e ++ff=dos即可将文件格式从 unix 更改为 dos。 它应该可以解决问题。 如果没有，:%s/\r//g应该可以帮助你。First, use
:set ff?to figure out the file format your file is.I guess it could be
unix, then the problem is your file was created withfileformat=dosadding "^M^J" to the line end but read withflieformat=unixonly removing the "^J" from the line end, leaving the "^M" there.Just input
:e ++ff=dosin Vim command line to change your file's format from unix to dos. It should solve the problem. If not,:%s/\r//gshould help you out.为了使 ^M 字符匹配，我必须直观地选择它，然后使用操作系统复制到剪贴板命令来检索它。 您可以在尝试替换命令之前通过搜索字符来测试它。
应该选择第一个坏行将
用回车替换所有错误的^M。
这是 MacVim 中的函数，它基于 gvim 7。
编辑：
在我的 Windows 10 机器上再次遇到这个问题，该机器有 Ubuntu for Windows，我认为这个导致 vim 的文件格式问题。 在这种情况下，将 ff 更改为 unix、mac 或 dos 只不过将 ^M 更改为 ^J 并再次更改回来。
这种情况下的解决方案：
我走这条路的原因是因为我想确保我的文件是非破坏性的。 我可以使用
:%s/\r$//g但这会直接删除回车符，并且可能会产生意想不到的结果。 相反，我们将单个 CR 字符（这里是 ^M 字符）转换为空格，然后删除行末尾的所有空格（无论如何，这对我来说都是一个理想的结果）抱歉重新提出一个早已得到解答的老问题，但似乎存在一些混乱，我想我会帮助澄清其中一些，因为这在谷歌搜索中排名很高。
in order to get the ^M character to match I had to visually select it and then use the OS copy to clipboard command to retrieve it. You can test it by doing a search for the character before trying the replace command.
should select the first bad line
will replace all the errant ^M with carriage returns.
This is as functions in MacVim, which is based on gvim 7.
EDIT:
Having this problem again on my Windows 10 machine, which has Ubuntu for Windows, and I think this is causing fileformat issues for vim. In this case changing the ff to unix, mac, or dos did nothing other than to change the ^M to ^J and back again.
The solution in this case:
The reason I went this route is because I wanted to ensure I was being non-destructive with my file. I could have
:%s/\r$//gbut that would have deleted the carriage returns right out, and could have had unexpected results. Instead we convert the singular CR character, here a ^M character, into a space, and then remove all spaces at the end of lines (which for me is a desirable result regardless)Sorry for reviving an old question that has long since been answered, but there seemed to be some confusion afoot and I thought I'd help clear some of that up since this is coming up high in google searches.
这些都不适合我，所以我尝试了这个，它有效：
输入
:%s/按 CTRL-VCTRL-M
输入 < code>//g
press Enter
因此，Vim 中的整体命令应类似于
:%s/^M//g这是做什么的：
:%s（查找并替换）/^M/（该符号）/（无字符）g（全局）。None of these worked for me, so I tried this, which worked:
type
:%s/press CTRL-VCTRL-M
type
//gpress Enter
So the overall command in Vim shoud look like
:%s/^M//gWhat this does:
:%s(find and replace)/^M/(that symbol)/(with no chars)g(globally).^M 由 Ctrl+V 和 M 检索，因此也是如此
^M is retrieved by Ctrl+V and M, so do
无需使用 Ctrl：
<代码>:%s/\r$//
Without needing to use Ctrl:
:%s/\r$//对我有用的简单事情
Simple thing that worked for me
我用 sed 做到了这一点：
sed -i -e 's/\r/\n/g' filenameI did this with sed:
sed -i -e 's/\r/\n/g' filename怎么样：
<代码>
:%s/\r//g
这对我来说完全有效。
它所做的只是清理所有行的行尾，它删除了 ^M ，仅此而已。
What about just:
:%s/\r//g
That totally worked for me.
What this does is just to clean the end of line of all lines, it removes the ^M and that's it.
这个问题还有很多其他答案，但以下内容仍然最适合我，因为我需要命令行解决方案：
说明：
myfile： e ++ff=dos强制重新加载整个文件作为 dos 行结尾。:w ++ff=unix以使用 unix 行结尾写入文件There are many other answers to this question, but still, the following works best for me, as I needed a command line solution:
Explanation:
myfile:e ++ff=dosto force a reload of the entire file as dos line endings.:w ++ff=unixto write the file using unix line endingsCtrl+M 最小化了我的窗口，但 Ctrl+Enter 实际上插入了一个
^M性格。 我还必须确保在两次按下之间不要松开 Ctrl 键。所以我的解决方案是：
其中
如果您正在处理 Windows 生成的文件
上述解决方案将在现有行之间添加额外的行，因为
^M后面已经有一个不可见的\r。为了防止这种情况，您需要删除
^M字符而不替换它们。其中
%表示“在此缓冲区中”，s表示“替换”，/表示“（查找）以下模式”，^M字符所需按下的按键（见上文），//表示“什么都没有”（或者，“这两个斜杠之间的模式是空的”），并且g是一个标志，意思是“全局”，而不是一行中第一次出现。Ctrl+M minimizes my window, but Ctrl+Enter actually inserts a
^Mcharacter. I also had to be sure not to lift off the Ctrl key between presses.So the solution for me was:
Where
<Ctrl-V><Ctrl-Enter>means to press and hold Ctrl, press and release V, press and release Enter, and then release Ctrl.If you are working on a Windows-generated file
The above solution will add an additional line between existing lines, because there is already an invisible
\rafter the^M.To prevent this, you want to delete the
^Mcharacters without replacing them.Where
%means "in this buffer,"smeans "substitute,"/means "(find) the following pattern,"<Ctrl-V><Ctrl-Enter>refers to the keys to press to get the^Mcharacter (see above),//means "with nothing" (or, "with the pattern between these two slashes, which is empty"), andgis a flag meaning "globally," as opposed to the first occurrence in a line.这对我有用：
\n行结尾）所以在vim中：
This worked for me:
\nline ending)So in vim:
就我而言，
以上都不起作用，我从我的Mac复制了一个CSV文件到Linux机器，我使用了上述所有命令，但没有任何帮助，但下面的命令
我有一个文件，其中^M字符夹在如下所示的行之间
In my case,
Nothing above worked, I had a CSV file copied to Linux machine from my mac and I used all the above commands but nothing helped but the below one
I had a file in which ^M characters were sandwitched between lines something like below
