It is not clear why you need threads to do this, more detail might be in order. perlthrtut would be a good point to start for info on threads. 

my $file = '/path/to/some/file';

while(1) {
    if ( -e $file ) {
        # read file
        # do stuff
        # unlink $file;  # otherwise we will keep finding it
    }
    sleep 1;
}

If you want to use simple code like this you will want to daemonize it. There is a example of daemonizing on my scratchpad
