sed多行替换问题 [英] Sed multiline replacement question

问题描述

我遇到了sed替换问题，希望你们中的一个能够为我提供帮助.我确定我缺少一些简单的东西.

I am having a sed replacement issue and am hoping one of you will be able to help me. I am sure I am missing something simple.

所以我有一个包含文本和引号的文件.引号本身可以在一行上，也可以跨多行.我希望报价单本身换行.作为示例，下面是文件

So I have a file containing text and a quote. The quote itself could be on one line or span multiple lines. I want the quote on a new line by itself. As an example here is an example of the file

And he said "This too
   shall pass"

我需要将其更改为

And he said 
"This too shall pass"

我尝试了以下sed，但无法正常工作-似乎匹配，但是无法换行

I tried the following sed but it didn't work -- it seems to match alright but failed to get a new line

/"This/ {
    N
    s/"This *\n*too *\n*shall *\n*pass"/\n"This too shall pass"/
}

推荐答案

尝试将\ n替换为\，并使用明确的新行；如下所示

Try replacing the "\n" with \ and an explicit new line; like the following --

/"This/ {
N
s/"This *\n*too *\n*shall *\n*pass"/\
"This too shall pass"/
}
