Top Forums Shell Programming and Scripting Matching 10 Million file records with 10 Million in other file Post 302654743 by methyl on Tuesday 12th of June 2012 08:33:11 AM

What Operating System and version are you running?

How big are the files?
Are either or both of the files in sorted order?
Do the records in each file match one-for-one?
Does the output order matter?

Can you post sample input and matching output?

Is this an extract from a database where it might be easier to work on the data while it is still in the database?
