As do an increasing number of CLI programs. The studies and human factors
that cause people to need progress have nothing to do with CLI vs GUI, it's
because the users are human.
Close but not quite. The reason we want feedback is because computers
are UNRELIABLE. Between the fact that a lot of software is crap and can
freeze without warning or you gave the computer a problem that can't be
solved in your lifetime, it's nice to know if something useful is
happening vs just being stuck in an infinite loop.
You're in the minority, even among CLI users, for wanting slience.
But, cdparanoia does exactly what we're saying it should, it has a --quiet
option for scripting, but prints out progress in the default case.
cdparanoia is a good example of a program that could easily get into a
infinite loop. Every time it gets a read error, it goes back and tries
to reread the disc. Without a counter to limit rereads, it would try
forever. So a simple little scratch on a CDROM could cause the system to
lock up an I/O channel. Problems like these are all over the place.
