Thank you for help. I tried to write this code based on my understanding. Please excuse me. I am very beginner of perl. My data contain unique ids (ID157) and name (TSR11) separated by tab. i want to look for both ids and name (ID157 TSR11) if they are present in all 25 files. If ID157 TSR11 is present in all 25 files, it should be printed in the output. This i want to print only those IDs and name that are present in all 25 files. and id and name should print together separated by tab as: ID157 TSR11. I am less familiar with using perl modules, but i am trying my best.
