Question

我试图将这一行分成多行，每行包含一个单独的句子：

This is a first sentence. This is a second sentence. Look at this: a third sentence! Where does this ends? I have no Idea, who knows…

我们必须使用尽可能短的命令。

我试过了：

sed 's/[.?!]/&\n/g'

但它会在每个新句子后添加一个空格：

This is a first sentence.
 This is a second sentence.
 Look at this: a third sentence!
 Where does this ends? I have no Idea, who knows…

请记住，我们必须尽量缩短线路

Answer 1

尝试使用GNU sed：

sed -r 's/([.?!]+) */\1\n/g' file

使用常规sed：

sed 's/\([.?!]\{1,\}\) */\1\
/g' file

这些测试用于一个或多个句子终止符后跟0个或多个空格。

Answer 2

试试这个，

sed 's/[.?!]/&\n/g' file | sed 's/^ //g'

Answer 3

您可以使用awk

awk '{gsub(/\. /,"."RS);gsub(/\? /,"?"RS);gsub(/\! /,"!"RS)}1' file
THis is a first sentence.
This is a second sentence.
Look at this: a third sentence!
Where does this ends?
I have no Idea, who knows.

或者这个:(它在行尾添加一个空格）

awk '{gsub(/[.!?] /,"&"RS)}1' file
THis is a first sentence.
This is a second sentence.
Look at this: a third sentence!
Where does this ends?
I have no Idea, who knows.
