Hi,
 
I am facing a problem with text file manipulation with Perl.
 
I have a file with over 2 lac lines of data. 
I need to find the duplicates(strings) in the file and copy those records into another 
file.
 
Is there a function/module  in Perl by which I can read the duplicates in a file at 
one go and print them 
on to another file.
 
Please help me.
 
Regards,
Mohit Jain
