That’s not designed to do what you hope. select(2) is a system call intended for use on network socket handles, not file handles. Since socket handles and file handles are compatible on a Unix type system (including CentOS) the call doesn’t fail, but it *cannot* report the information you’re hoping to get.
I would first try calling the -w operator:
print_to_file() if -w $fh;
