Splitting large text file on every blank line

Question

I\'m having a bit trouble of splitting a large text file into multiple smaller ones. Syntax of my text file is the following:

Answer 1

awk -v RS="\n\n" '{for (i=1;i<=NR;i++); print > i-1}' file.txt

Sets record separator as blank line, prints each record as a separate file numbered 1, 2, 3, etc. Last file (only) ends in blank line.

Answer 2

Setting RS to null tells awk to use one or more blank lines as the record separator. Then you can simply use NR to set the name of the file corresponding to each new record:

 awk -v RS= '{print > ("whatever-" NR ".txt")}' file.txt

RS: This is awk's input record separator. Its default value is a string containing a single newline character, which means that an input record consists of a single line of text. It can also be the null string, in which case records are separated by runs of blank lines, or a regexp, in which case records are separated by matches of the regexp in the input text.

$ cat file.txt
dasdas #42319 blaablaa 50 50
content content
more content
content conclusion

asdasd #92012 blaablaa 30 70
content again
more of it
content conclusion

asdasd #299 yadayada 60 40
content
content
contend done

$ awk -v RS= '{print > ("whatever-" NR ".txt")}' file.txt

$ ls whatever-*.txt
whatever-1.txt  whatever-2.txt  whatever-3.txt

$ cat whatever-1.txt 
dasdas #42319 blaablaa 50 50
content content
more content
content conclusion

$ cat whatever-2.txt 
asdasd #92012 blaablaa 30 70
content again
more of it
content conclusion

$ cat whatever-3.txt 
asdasd #299 yadayada 60 40
content

contend done

Try this bash script also

#!/bin/bash
i=1
fileName="OutputFile_$i"
while read line ; do 
if [ "$line"  == ""  ] ; then
 ((++i))
 fileName="OutputFile_$i"
else
 echo $line >> "$fileName"
fi
done < InputFile.txt
