I'm trying to replace each , in the current file by a new line:
我试着用新的一行来替换当前的文件:
:%s/,/\n/g
But it inserts what looks like a ^@ instead of an actual newline. The file is not in DOS mode or anything.
但它插入什么看起来像一个^ @而不是一个实际的换行符。该文件不属于DOS模式或任何内容。
What should I do?
我应该做什么?
If you are curious, like me, check the question Why is \r a newline for Vim? as well.
如果你很好奇，就像我一样，问一下为什么\r是Vim的换行符?。

Use \r instead of \n.
Substituting by \n inserts a null character into the text. To get a newline, use \r. When searching for a newline, you’d still use \n, however. This asymmetry is due to the fact that \n and \r do slightly different things:
用\n替换将一个空字符插入到文本中。要得到一条新行，请使用\r。但是，在搜索新行时，仍然使用\n。这种不对称性是由于\n和\r做了稍微不同的事情:
\n matches an end of line (newline), whereas \r matches a carriage return. On the other hand, in substitutions \n inserts a null character whereas \r inserts a newline (more precisely, it’s treated as the input <CR>). Here’s a small, non-interactive example to illustrate this, using the Vim command line feature (in other words, you can copy and paste the following into a terminal to run it). xxd shows a hexdump of the resulting file.
\n匹配行尾(换行)，而\r匹配回车。另一方面，在替代中插入一个null字符，而\r插入一个换行符(更准确地说，它被当作输入
echo bar > test
(echo 'Before:'; xxd test) > output.txt
vim test '+s/b/\n/' '+s/a/\r/' +wq
(echo 'After:'; xxd test) >> output.txt
more output.txt
Before:
0000000: 6261 720a bar.
After:
0000000: 000a 720a ..r.
In other words, \n has inserted the byte 0x00 into the text; \r has inserted the byte 0x0a.
换句话说，\n将字节0x00插入到文本中;\r插入了字节0x0a。

Here's the trick:
关键之处在于:
First, set your vi(m) session to allow pattern matching with special characters (ie: newline). It's probably worth putting this line in your .vimrc or .exrc file.
首先，设置vi(m)会话，以允许模式匹配特殊字符(例如:newline)。将这一行放到.vimrc或.exrc文件中可能是值得的。
:set magic
Next, do:
接下来,做:
:s/,/,^M/g
To get the ^M character, type Control-v and hit Enter. Under Windows, do Control-q, Enter. The only way I can remember these is by remembering how little sense they make:
M ^字符,类型- v和回车。在Windows下，执行Control-q，输入。我能记住这些的唯一方法是记住它们的意义:
A: What would be the worst control-character to use to represent a newline?
A:用来表示换行的最坏的控制字符是什么?
B: Either
q(because it usually means "Quit") orvbecause it would be so easy to type Control-c by mistake and kill the editor.B: q(因为它通常意味着“退出”)或v，因为它很容易在错误中键入Control-c，并杀死编辑器。
A: Make it so.
答:让它如此。

In the syntax s/foo/bar \r and \n have different meanings, depending on context.
根据上下文，在语法s/foo/bar \r和\n中有不同的含义。
For foo:
\n = newline
\r = CR (carriage return = Ctrl-M = ^M)
为foo:\ n =换行符\ r = CR(回车= Ctrl-M = ^)
For bar:
\r = is newline
\n = null byte (0x00).
对于bar: \r =是newline \n = null字节(0x00)。

Here is a list of the ASCII control characters, insert them in vim via CTRLvCTRL---key---.
In bash or the other unix/linux shells just type CTRL---key---. Try CTRLM in bash, its the same as hitting ENTER, as the shell realizes what is meant, even though linux systems use Line Feeds for line delimiting. Just the control char for Line Feed is CTRL-A, which is bound to 'jump to beginning of line' in bash.

This is the best answer for the way I think but it would have been nicer in a table: https://*.com/a/12389839/962394.

So, rewording:
所以,说辞:
You need to use \r to use a line feed (ascii 0x0a, the unix newline) in a regex replacement but that is peculiar to the replacement - you should normally continue to expect to use \n for line feed and \r for carriage return.
您需要使用\r在regex替换中使用一个行馈线(ascii 0x0a, unix换行)，但这是替换的特殊情况—您应该正常地继续期望使用\n来进行换行，并使用\r作为回车。
This is because vim used \n in a replacement to mean the NIL character (ascii 0x00). You might have expected NIL to have been \0 instead, freeing \n for its usual use for line feed, but \0 already has a meaning in regex replacements so it was shifted to \n. Hence then going further to also shift the newline from \n to \r (which in a regex pattern is the carriage return character, ascii 0x0d).
这是因为vim在替换中使用\n，以表示NIL字符(ascii 0x00)。您可能会认为NIL已经是\0了，但是，对于它通常用于换行的使用，它已经释放了，但是\0已经在regex替换中有了意义，所以它被转移到\n。因此，进一步将换行符从\n改为\r(在regex模式中是回车字符ascii 0x0d)。
character | ascii code | C representation | regex match | regex replacement -------------------------+------------+------------------+-------------+------------------------ nil | 0x00 | \0 | \0 | \n line feed (unix newline) | 0x0a | \n | \n | \r carriage return | 0x0d | \r | \r | <unknown>
NB: ^M (Ctrl-V Ctrl-M on linux) inserts a newline when used in a regex replacement rather than a carriage return as others have advised (I just tried it).
注:^ M(ctrl - v Ctrl-M linux)中使用一个正则表达式替换时插入一个新行,而不是一个回车,其他人则建议(我试过)。
Also note that vim will translate the line feed character when it saves to file based on its file format settings and that might confuse matters.
还要注意的是，vim将根据其文件格式设置将行提要字符转换为文件，这可能会混淆问题。
