File Test Question

[Dave Adams]

*My Code:*

my $logfile = "logfile_with_content";
if (-w $logfile) {
    print ("True - file exists but empty");
}
if (-s $logfile) {
    print ("True - file exist and has content");
}

*My Output:*

True - file exists but empty True - file exist and has content

*My Question:*

Why do both test evaluate to true when the file called
"logfile_with_content" is 5K in size?  I would expect the second file test
to only work?  Any advice?

Thanks
