in thread Error when running on larger files
Use of uninitialized value in subtraction (-) at line 117, <$IN2> line + 4148567. Use of uninitialized value in numeric gt (>) at line 118, <$IN2> line +4148567. Use of uninitialized value $F2 in hash element at line 119, <$IN2> +line 4148567. Argument "" isn't numeric in sort at line 127, <$IN2> line 4148567.
Instead of randomly reshuffling the file, could you not extract that 1 line (head -4148567 <file> | tail -1) and then run your script against that 1 line? If I head to guess, seeing that $F is the culprit, I'm guessing you have a double tab on that particular line.
update:Nevermind ... I shouldn't answer questions without first reading the whole thing and second not having finished my morning cup of coffee.
