Hello, I have two large files. They both have common key field, but in different place. I want to see if file_1's records exist in file_2 or not. If exists then I would like to know which one. Is there any readily available routine in perl or not. If not what is the best way to do this. Both files are very large.

In reply to Comapring files to see if one file's records is in another file or not. by jatinpatel
