I always find repeated "print OUT" a bit clunky. Two alternatives:
$outputFile = "fulltoc.htm";
open(OUT, ">",$outputFile) or die "couldn't open outputfile: $!";
select OUT;
print ("<HTML><HEAD><TITLE>");
print ("Detailed Table of Contents\n");
print ("</TITLE></HEAD><BODY>\n");
Or:
$outputFile = "fulltoc.htm";
open(OUT, ">",$outputFile) or die "couldn't open outputfile: $!";
print OUT "<HTML><HEAD><TITLE>"
. "Detailed Table of Contents\n"
. "</TITLE></HEAD><BODY>\n";
Note that with the first approach, you'd have to explicitly print to STDOUT when you want to print to the screen:
print STDOUT "$file\n";
I was also surprised by this line:
next if $file =~ m/^\.htm$/i;
next unless $file =~ m/\.htm$/i; # not this?
