I am writting the below code .
I have to serch the lines containing strings in between the top name.
The top names are AR,AZ...

PHP Code:
echo "Give the top name"
read top
/usr/bin/sed -'/$top/,/$top/p' inputfile | /usr/bin/sed '/,/\\n/g' exclude_file

Code:
age

roll
section
evin
25
80

Code:
awk '/AR/ {f=(!f);next} f' RS=",|\n"

This has a problem since AR is not separate from the text. It then does not print last line.
ame comes first then age and rest
