Hello all, Once again im alittle stuck and my ideas seem to surpass my ability. I'm trying to compare two files that store info on my SUID files for changes and print the details to a web page, im happy with it for the most part, I understand why the output is not produced but have no idea what so ever how to remede the situation. 
    #!/usr/bin/perl -w

use strict;

my $setuidtoday = "/var/log/setuid.today";
my $setuidyest = "/var/log/setuid.yesterday";
my $DIFF = "/usr/bin/diff";

print "Content-type: text/html\n\n";
print "<HTML><TITLE>SET SUID FILE CHECK</TITLE>\n";
print "<BODY BGCOLOR=#000000 Text=#008000 link=#00c000\n";
print "<H1>SET SUID FILE CHECK</H1>\n";

if(-e $setuidtoday && $setuidyest) {
        print "<H6>Setuid lists exist!</H6>\n";
        print `$DIFF $setuidtoday $setuidyest`;
}
print "</BODY></HTML>";

I believe its this line 
print `$DIFF $setuidtoday $setuidyest`;

It works fine at the CLI but the output from diff is not displayed in the webpage, I can see why that is but dont know how to fix the issue... Also if anyone has any improvements please say. The reason I have not used any modules for HTML prasing etc... is because I haven't got that far in my study and i'd like to see what I can code with base perl before I branch out.
