I have a big file with more than 3264880 lines. I wanted to split that file based on Two strings "BEGIN JOB" and " END JOB" and write it into multiple files and the file name should be based on a certain Identifier which is present between the lines BEGIN JOB and END JOB

Sample data

BEGIN JOB
 Identifier "ADHOC_Extract"
 DateModified "2018-10-02"
 TimeModified "15.09.52"
 BEGIN DSRECORD
 Identifier "ROOT"
 OLEType "CJobDefn"
 Readonly "0"
 Name "ADHOC_Extract"
END JOB

BEGIN JOB
 Identifier "HOC_Extract"
 DateModified "2018-11-02"
 TimeModified "12.09.52"
 BEGIN DSRECORD
 Identifier "ROOT"
 OLEType "CJobDefn"
 Readonly "0"
 Name "HOC_Extract"
END JOB

Output expected as two files since my sample has just two... But it will have more than 1000 such repeated patterns

ADHOC_Extract.txt

BEGIN JOB
 Identifier "ADHOC_Extract"
 DateModified "2018-10-02"
 TimeModified "15.09.52"
 BEGIN DSRECORD
 Identifier "ROOT"
 OLEType "CJobDefn"
 Readonly "0"
 Name "ADHOC_Extract"
END JOB

 HOC_Extract.txt

BEGIN JOB
 Identifier "HOC_Extract"
 DateModified "2018-11-02"
 TimeModified "12.09.52"
 BEGIN DSRECORD
 Identifier "ROOT"
 OLEType "CJobDefn"
 Readonly "0"
 Name "HOC_Extract"
END JOB

I am ok even to write a shell script for the same

#!/bin/bash
cat test.txt| while read; do
 [ "$REPLY" = "BEGIN JOB" ] && begin=1 && continue
 if [ $begin = 1 ] && [[ "$REPLY" =~ Identifier ]];then
 filename=$REPLY#*"
 filename=$filename%".txt
 begin=0
 echo "BEGIN JOB" > "$filename"
 echo "$REPLY" >> "$filename"
 else
 echo "$REPLY" >> "$filename"
 fi
done
