Shell Programming and Scripting

Hi.I have two files say XXX.dat and YYY.dat

The contents of XXX.dat and YYY.dat are as follows

XXX.dat

Jan
Feb
Mar
Apr
Method 1
{
echo "This is method 1"
}

YYY.dat

Delhi
Culcutta
One
Two
Three
Four
Five
Chennai
Mumbai

Now I want the insert only three lines of YYY.dat(line numbers 3 to 7) into XXX.dat above method 1(at line number 5)Method 1 may come anywhere in XXX.dat and the insertion into XXX.dat is purely dependent on method 1.Please give a solution based on the line number of method 1,as there may be many method 1 s and I want to insert only for the first occurance of method 1.Hopefully I want a solution based on line numbers,not based on patterns.Thank you,

$ cat 1.awk
NR==FNR{if(NR>=3 && NR<=7) arr[i]=$0; i++; next}
{
if($0 == "Method 1") for (i in arr) print arr[i]
print
}

$ awk -f 1.awk YYY.dat XXX.dat

Method 1
{
echo "This is method 1"
}

no...The first one is inserting a file into another file after a line number whereas the new one is respect to inserting specified lines of a file above a line number(or a specified pattern).Thanks

when match 'pat' on a.txt, insert the content of b.txt above matched line in a.txt.

Code:

open FH,"<b.txt";
while(<FH>){
	push(@arr,$_);
}
close FH;
open FH,"<a.txt";
while(<FH>){
	if(index($_,"pat")==0){
		for $item(@arr){
			print $item;
		}
		print $_;
	}
	else{
		print;
	}
}
close FH;
