使用 awk 将句子合并为一行

我已经通过命令提取了数据并将其保存在 kwrite 文件中，但现在我想从中检索一些重要数据，但理想情况下数据应该在 1 行，而在我的例子中，它分成 2、3 行。以 Jpak 开头的行是值得关注的。数据：

Jpak= its just a sample data for posting,
solve the query asap

Breadth=44


***** less*****
--
Effective search space used: 2418848120


Jpak= To work late into the night, alluding to the
 time before electric lighting

Breadth=75


***** less*****
--


Jpak= Speak of an issue, (mostly current) which ,
many people ,
are talking 

Breadth=22


***** less *****
- -

期望输出：

Jpak= its just a sample data for posting solve the query asap

Jpak= To work late into the night alluding to the time before electric lighting

Jpak= Speak of an issue (mostly current) which many people  are talking

答案1

纯sed溶液

抱歉，我对不太熟悉awk，但是这可以完成工作：

sed '/Jpak=/,/^$/!d' sample|sed ':a;N;$!ba;s/\n//g;s/,/ /g;s/ \{2,\}/ /g;s/Jpak/\n\nJpak/g'

聚集在一起sed1行和如何使用 sed 替换换行符 (\n)？。

输出

Jpak= its just a sample data for posting solve the query asap

Jpak= To work late into the night alluding to the time before electric lighting

Jpak= Speak of an issue (mostly current) which many people are talking

使用此命令链，输出以两个空行（此处未显示）开始，添加到|sed '1,2d'链的末尾以删除它们。

答案2

perl -n00E '/Jpak=/ and s/\s+/ /g and say' ex.txt
  • -n00E-- 对于每个以空行分隔的段落执行...
  • /Jpak=/ and——找到所需的模式并……
  • s/\s+/ /g-- 用单个空格替换空格、换行符和制表符序列
  • and say——并说出发现了什么。

输出为：

Jpak= its just a sample data for posting, solve the query asap 
Jpak= To work late into the night, alluding to the time before electric lighting 
Jpak= Speak of an issue, (mostly current) which , many people , are talking
