用换行符和“ [英] sed with newlines and "

问题描述

我有一堆看起来像这样的文本文件:

I have a bunch of textfile that looks like this:

His doctor attributed this to an allergy .

That hardly convinced him , as he had no history of allergies of any kind .
" Yet , that was to be the least of his problems .
I may have to take steroids for the rest of my life .
"
A topical steroid spray was later added to his repertoire of drugs and 
" he knew it was merely masking the underlying condition .
"

我想更改它，以使. "在一行中.所需的输出应如下所示:

And I want to change it such that the . " are in a single line. The desired output should look like this:

His doctor attributed this to an allergy .

That hardly convinced him , as he had no history of allergies of any kind .
" Yet , that was to be the least of his problems .
I may have to take steroids for the rest of my life . "
A topical steroid spray was later added to his repertoire of drugs and 
" he knew it was merely masking the underlying condition . "

我已经尝试过了，但是不起作用:

I've tried this but it doesn't work:

sed -i 's/.\n"\n/. "\n/g'

有人可以帮助我执行正确的sed命令来将"向上移动吗?

Can someone help me out on the correct sed command to shift the " up?

推荐答案

这是我想出的:

sed -n '1{h;d};/^"$/{g;s/$/ "/p;n;h;d};x;p;${g;p}' input.txt

输出

His doctor attributed this to an allergy .

That hardly convinced him , as he had no history of allergies of any kind .
" Yet , that was to be the least of his problems .
I may have to take steroids for the rest of my life . "
A topical steroid spray was later added to his repertoire of drugs and
