in reply to Controlling already printed text to console.
The technique described by frozenwithjoy will work provided you haven’t moved the cursor to a new line. In addition to \r (carriage return), which moves the cursor to the start of the line, there is also \b (backspace), which moves the cursor back a single character.
For anything more complicated, you probably need a CPAN module, and you will likely have to get a module suitable for your OS:
- For Windows there is Win32::Console.
- For *nix you might investigate Curses (which won’t install on my Windows system).
