There are 2445 entries in file 1 and 2431 entries in file 2. File 1 is 264KB and file 2 is 352 KB. file 2 has a lot more columns.
The pattern in column 3 in file 1 can exist in several lines in file 2 but only once in file 1. So I need to read in column 3 in every line from file 1 and look for a match in every line in file 2. And also the pattern in column 3 in file 1 can also "not" exist in file 2 and then this happens I want to just print the line from file 1 with nothing appended.
RudiC, Can I put an else in your code to print the line from file 1 when no matches occur? Something like so?
