Sed multiline replacement question

Question

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.

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"

I need to change this to

And he said 
"This too shall pass"

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"/
}

Answer 1

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"/
}
