根据特定的模式独立的单一文本文件分割成多个文件 [英] Separate single text file into multiple files based on certain pattern

问题描述

假设我有以下文件：（Song.txt）

Suppose I have the following file: (Song.txt)

Song one
bla bla bla bla 
bla bla bla bla bla
Song two
yaya ya yaa 
blaaa bla bla blaaaaa
Song three
bla bla bla

我想将这个文件分为三个文件是这样的：

I want to separate this file into three files to be like the following:

首先文件名应为Song_1.txt

First filename should be Song_1.txt

Song One
bla bla bla bla 
bla bla bla bla bla

二名应该是Song_2.txt

Second filename should be Song_2.txt

Song two
yaya ya yaa 
blaaa bla bla blaaaaa

三文件名应该是Song_3.txt

Third filename should be Song_3.txt

Song three
bla bla bla

我怎么可以这样用awk，grep的，PERL，Python和/或任何基于UNIX的工具和可用的语言？

How can I do this using awk, grep, perl, python, and/or whatever unix-based tools and languages available ?

推荐答案

这应该帮助 -

gawk -v RS="Song" 'NF{ print RS$0 > "Song_"++n".txt" }' Song.txt

测试：

[jaypal:~/Temp] cat Song.txt 
Song one
bla bla bla bla 
bla bla bla bla bla
Song two
yaya ya yaa 
blaaa bla bla blaaaaa
Song three
bla bla bla

[jaypal:~/Temp] gawk -v RS="Song" 'NF{ print RS$0 > "Song_"++n".txt" }' Song.txt

[jaypal:~/Temp] ls -l S*
-rw-r--r--  1 jaypalsingh  staff  113 28 May 17:55 Song.txt
-rw-r--r--  1 jaypalsingh  staff   47 28 May 18:06 Song_1.txt
-rw-r--r--  1 jaypalsingh  staff   45 28 May 18:06 Song_2.txt
-rw-r--r--  1 jaypalsingh  staff   24 28 May 18:06 Song_3.txt

[jaypal:~/Temp] cat Song_1.txt 
Song one
bla bla bla bla 
bla bla bla bla bla

[jaypal:~/Temp] cat Song_2.txt 
Song two
yaya ya yaa 
blaaa bla bla blaaaaa

[jaypal:~/Temp]
