Some commandline programs write, per example, percentage of completion in the
screen.
Those programs usually write a line, and update the numbers by overwriting over
the same line continuously.

Is this possible with writef/writefln or another function already made in
Phobos?

You can achieve this by writing a \r (instead of \n) at the end of line. 
  I don't know if this works the same way in Linux, though.

Works exactly the same in Linux.

A problem is the writef-doesn't-flush thing, thing though. Unless you write out
a newline somewhere, your writefs won't do anything at all. You can get around
this by using stdout.writeString from std.string instead.

or calling std.c.stdio.fflush(stdout) should work.
