How can I dynamically update a value on STDOUT? I have a value that uses File::Tail to parse a log and return a valu each time, which is working. The idea is that it gives the user a realtime summary status of the application. However, when displaying the results, I don't really need to show a history of values, only the current value on STDOUT. In other words, instead of printing out the following as a string:

1 3 10 20

it should print 1, then replace that with a 3, then replace that with a 10, then with 20, as it parses the file and determines the value.

I had thought that using 

use IO::Handle;

*STDOUT->autoflush();

would work, but it seems to be for something else. What is the suggested way of doing this?
