Replacing carriage return ^M with Enter

Question

我知道如何在我的文件中删除^M （ %s/^M//g ），但这只是一行，我想用输入替换^M ...什么是VIM中的输入字符（使用在commnad-line模式下）。

Answer 1

To replace carriage return character (which is <Cm> ) with line feed character (which is unix line break character) you should run a bit strange command:

%s/\r/\r/g

It looks like if it is doing nothing, but in regular expressions and double-quoted strings carriage returns are represented using \\r and line feeds with \\n , while in the replacement part of :s command and substitute() function they mean the opposite.

Note that in terminal Enter produces <Cm> , so your initial request is not valid.

Answer 2

:%s/\\r//g only works when:

• set ff=unix , which when done, automatically converts all CRLF to LF

• set ff=dos and CR is a rogue char that is not preceded by LF, eg, inserted with CV CM .

  CR in LF CR pairs will not be found.

Therefore, if all you want is to convert every LF CR to LF , you should use:

:set ff=unix
:w

Answer 3

You can replace one character using r<CR> in normal mode.
Or you can enter a "return" in command line mode by typing <Cv><CR> .

Answer 4

In vim session try:

:%s/^M//g

Where ^M is achieved by ctrl+V+M keystrokes together.

Answer 5

类似于@ZyX和@anubhava，但假设您只是想从Windows文件中删除讨厌的回车符，以下就足够了：

:%s/\r//g
