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).

    Oh, thnks for the "\b" addition - it is useful for my case.

    I do not need more complicated stuff. What have been said, enough for me!

    And it is Linux OS.
