It depends somewhat on the system, and above all, how much you want to overwrite. For a lot of simply programs, outputting
'\r'will do the trick: it will return the cursor to the start of the line (on almost all consoles), and you can overwrite the line. (I’ve used this in the past for continuously updated progress reports:n records processed, for example. Just be sure to not output a'\n'until you’re ready.For anything more complex, the usual solution is the
curseslibrary. It should be present on most Unix (sometimes under the namencurses), and there’s a port ofncursesto Windows as well. (The generic name of the library, and its name under traditional Unix, iscurses;ncursesis a GPL implementation the library.)
