Below I have got while loop which check some conditions and It works. I am looking forward if any one can suggest me how to make it more compact. Any suggestions?Please. 
    
    while (<$fh>)
    {
        if (/^M/)
        {
            my @output = split('/');
            my $filename = $output[-1];
            chomp($filename);

            if ($filename eq 'people.pdf')
            {
                $people = "1"
            };
            if ($filename eq 'animal.pdf')
            {
                $animal = "1"
            };
            if ($filename eq 'setup.msi')
            {
                $msi = "1"
            };
        }
    }
    if (!(defined $people))
    {
        print "People not found\n";
    }
    if (!(defined $animal))
    {
        print "animal not found\n";
    }
    if (!(defined $msi))
    {
        print "MSI file not found\n";
    }
    exit;
