Hi monks -simple question but i have difficulty finding it I have a script that looks for a match in a log file and once it's found it will display it --- now because i 'm looking for 3 parameters at the same time i need to highlight the matches found in red,green and blue so i can see where they are in a log file -so far i was unable to find this -but it's pretty easy to do with grep but not in perl--suggestions? 

sub file_in_out {
@ARGV == 3 || die "usage: $0 PATTERN LOGNAME DATE \n";
my ( $PAT, $LOG, $DATE ) = @ARGV;

open (my $HAN, $LOG) || die "Cannot open '$LOG' because: $!";
#print "ENTRIES FOUND FOR PATTERN = $PAT, LOGFILE=$LOG, DATE=$DATE....
+.............\n";
while ( <$HAN>) {
    next unless /$DATE/;
    print
      "\n",
      "---------------------------------------------------------------
+--------------------------------------------------------\n",
      $_ 
          if /$PAT/;
          }
