Hello, Can someone help out with a perl script to compare two files and print the difference along with segment name under which the difference is 

Requirement
I have tst1.txt and tst2.txt 
tst1.txt have data as below
Note: ABCD & EFGH are segments in below data
ABCD
     TEST1
     TEST2
     TEST3

EFGH 
     TEST1
     TEST2
     TEST3

tst2.txt have data as below
ABCD
     TEST1
     TEST2
     TEST3
EFGH 
     TEST1
     TEST2
     TEST3
     TEST4
     TEST5

Now diff between two files is in tst2.txt the last two rows "TEST4", "
+TEST5"
I need to have a script which gives output as below
Diff between two files is from segment
EFGH
     TEST4
     TEST5

I am calling EFGH as segment, and it is must to have it in output file eventhough segment name is same from both files(ex: EFGH from above data). Also the the text files contains around 2 thousand to 3 thousand records. I need to find out difference along with under which segment(Name) the difference is. Pls help..
