两个词之间删除换行符 [英] Remove newlines between two words

问题描述

我有一个看起来像一个文件：

I have a file that looks like:

name: charles
key1: how
are
you?
name: erika
key2: I'm
fine,
thanks
name: ...

我怎么能删除新行说，关键\\ D +和名的？它应该是这样的：

How could I remove the new lines that between "key\d+" and "name:"? It should look like this:

name: charles
key1: how are you?
name: erika
key2: I'm fine, thanks
name: ...

我试图用sed或awk的，但没有成功。有没有什么办法，以清洁工作线？

I'm trying to use sed or awk but without any success. Is there any way to clean that lines?

有什么办法去除之间的换行符键\\ D +和\\ W +：

Is there any way to remove the newlines between "key\d+:" and "\w+:"?

推荐答案

这样的事？

kent$  awk '/^key.:/{p=1}/^name:/{p=0}
            {if(p)printf "%s",$0;else printf "%s%s\n", (NR==1?"":RS),$0}' file
name: charles
key1: howareyou?
name: erika
key2: I'mfine,thanks
name: ...

处理空间：

awk '/^key.:/{p=1}/^name:/{p=0}
    {if(p)printf "%s%s",(/^key.:/?"":" "),$0;
    else printf "%s%s\n", (NR==1?"":RS),$0}' file

输出：

name: charles
key1: how are you?
name: erika
key2: I'm fine, thanks
name: ...
