Updates on "mv", "cp" commands

[BRAGA, Bruno]

Hi,

I don't know if that's the place to post this question, but I am sure
someone here will be able to give me hints on how to proceed.

I would like to propose and patch improvements on the "mv" (move) and
"cp" (copy) commands, by adding options for progress information.

The idea is that any GUI actions already do it graphically, and other
CLI applications, such as "rsync", have this as an extended option
"--progress". This is handy for large files processing, for instance.

Can anyone give me a little help? Maybe this is even an old idea that
was discarded because of performance reasons, I don't know..

Thanks in advance,

Braga, Bruno

this is the place for such things, but this topic has come up before and
rejected (for specific commands).  if you search the mail archives, you'll
find references to an accepted solution (a helper utility that outputs
progress bars based on feedback from arbitrary utilities).  while people have
posted patches for the first (rejected) method, no one has done things for the
latter method.

As good as any.

Here are some discussions I've met:

Thanks, Mike.

I got the references of this discussion (Thanks Kamil), and see the actually
this talk is long. Well, I still think it stinks to use rsync for such task,
but the addition of repetitive code for each applications really calls for
more generic implementation underneath them, as some people has commented.

Sorry for bringing this topic up again (somehow I searched the wrong
places), but it would be nice to find a solution that could work for
everything. We could just leave "disabled" by default, if the performance is
at hand.

Thank you all for the comments.

Regards,
