[Yum] progress bars

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Background:

- I'm an old UNIX fogey.

- This is my first YUM post.

- I run Yum to update my Fedora installations.  Usually from a local
  mirror, using localupdate.

- I save a transcript of each YUM session (an audit trail)

Yum produces a *lot* of output.  Most of it is not worthwhile.  For
example, my FC4 update, reflecting changes over the period June 18 to
July 2, generated 6.5M of transcript!

Furthermore, the transcript is littered with ^M (CR) characters.
(These seem to mean, essentially, discard anything to the left on this
line.)  This is not a UNIX convention.  CR is not guaranteed to do
anything on a UNIX standard out.  Visual programs may use curses (or
raw termcap/terminfo) to find out what to use to get this effect.  In
my environment the answer would be: nothing (this terminal's
termcap/terminfo entries give no such capability).

Is there a way to turn off this progress indication?  The manpage does
not list one.

For my purposes, the progress shown by "rpm -iv" is OK.  It does not
involve CR.  The amount of extra output is modest.
