...all i need it to say is Car Record Not Found once not multiple times...

You have the following:

... foreach my $carroadnameverify2 (@lines) { if ( $carroadnameverify2 =~ /$carroadnameverify/ ) { my $format = " %-13s %-15s %-12s %0s"; printf( "$format", split /\:/, "$carroadnameverify2" ); } else { printf("CAR RECORD NOT FOUND"); } } # END FILE LOOP ...

Indeed, if you have 10 non-matches within the foreach loop, "CAR RECORD NOT FOUND" will be printed 10 times. It seems, however, that you may be looking for something like the following:

... my $found = 0; foreach my $carroadnameverify2 (@lines) { if ( $carroadnameverify2 =~ /$carroadnameverify/ ) { my $format = " %-13s %-15s %-12s %0s"; printf( "$format", split /\:/, "$carroadnameverify2" ); $found = 1; } } # END FILE LOOP printf("CAR RECORD NOT FOUND") if !$found; ...

This just uses $found as a flag; if it's not set (i.e., if the item wasn't found in the array), the "CAR RECORD NOT FOUND" message is printed only once.
