wget/sftp- style progress bar

[Harry]

Hello,

I have a list of length operations I need to carry out. For each item
in this list, I want to display current progress on a single line only
(instead of multiple lines per item) as is done by such programs as
wget and sftp.

Now, I can obviously use the <backspace> character to seek to earlier
point on the current line. But before I do all of that manual and ad
hoc computations, I'm wondering if there's any helpful package that
has already though through this problem... so that I deal only in
higher abstractions such as fields, field lengths, left/right
justified field value, truncate field value (vs extend field length if
value is longer), etc.

Regards,
/HS

I'm not absolutely sure what you are looking for but maybe Curses will
be of some help.

Did you check CPAN?

I found this after only a couple of seconds:

http://search.cpan.org/~fluffy/Term-ProgressBar-2.09/

which looks to be the sort of thing you want.

ProgressMonitor is field oriented and oop-ish. There's other modules in
other or simpler styles that I imagine do the trick too.

Maybe Term::Sprog is of some use.
