In that case i would suggest you to work around with the following code i am sure you will get some result

awk '\
/Receipt/,/Canceled/ {
if (new_group==0)
{print substr($0,index($0,"Receipt"))
new_group=1}
else
{if (match($0,"Canceled"))
{print substr($0,1,index($0,"Canceled")-1)
new_group=0}
else
print
}
}' test.txt

Thanks for replying me i had try to use and i had seen that it's working fine with groups but the code which you had provide me is not helping me a lot is there any other solution apart from it.

I think if you want to extract text lines between two strings then you code has to be some what different and the above code will be helpful for me but if you want you can also try to take reference of this code hope you will get some idea from it and will be able to get what exactly you are get

awk '
/Receipt/ {s=x} 
{s=s$0"\n"} 
/Line13/ {p=1} 
/Canceled/ && p {print s;s=x;p=0}
' file

Hello friends,

I am also facing similar type of issue where i am trying to extract string from a string for example

$string = UPDATE "pqr"."def" FROM "pqr"."def" AS A SET "C1"=A."xy", "y"=A."b", "z"=A."xy"

Where my result should be the text between UPDATE and FROM which is
"pqr"."def" and for more information i had try to use substr() but that didn't helped me a lot.

If you want to extract text lines between two strings then you can use the below code where and i would suggest you to use UPDATE at the beginning of the string this would be very good for you and here is the code for the same, i hope you would understand what do i mean to say

$string =~ /UPDATE([\s\S]+?)FROM/;
$between = $1;
