    Hello PilotinControl,

    The output “Car Record Not Found” appears multiple times because it is within a loop. You need to change the logic to something like this (untested):

    my $found = 0; foreach my $carroadnameverify2 (@lines) { if ($carroadnameverify2 =~ /$carroadnameverify/) { printf " %-13s %-15s %-12s %0s", split(/:/, $car +roadnameverify2); $found = 1; last; } } print "CAR RECORD NOT FOUND" unless $found;

    (This assumes that each car record appears no more than once in the input file. If this is not the case, remove the last; statement from within the if clause.)

    Hope that helps,

    ...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.
