in thread open failure code

You could also use this type of contruct 

open(FH,"<".$log) ? print "opened\n" : print "unable to open $!\n";

it's not any better at all just making you aware of another option.

    Though this works, the ternary operator, like the grep and map operators, should not really be use in void context. 
    if (open(FH,"<".$log) {
    print "opened\n";
}
else {
print "unable to open $!\n";
}

    is preferred.

      Of course the same could be done just with proper logical short circuit operators. Prefer the low-precedence ones for this sort of thing: 

      open FH, "<", $log and print "Success\n" or print "Failure\n";

      That avoids trinaries and if/else's.
