[Bug-tar] RFC: quiet-option for tar-1.19

[Harald Koenig]

Hello *,

this is not (really) a bug report but a RFC for a new feature/option 
which I'm already using for years (based on request of some colleagues).

this quiet-option might be usefull for other tar users too, so here is my patch 
(attached).


rationale for the patch:  using "tar --compare" gives very verbose output 
if owner/group/permissions have changed (e.g. when extracting a source tar file
from the net and later I'd like to check which source files I have 
modified/patched).
this makes it somewhat hard not to miss the "important" output lines (e.g. 
size/md5 changed).

the patch adds a new option "-Q" or "--quiet" which gives adds two "quiet 
levels"
(giving 3 verbosity level alltogether: "normal default", "reasonable quiet"
and "completely quiet" (more or less a > /dev/null) when specified twice).

over the time, I only use the first quiet level, the additional "-QQ" feature
seems to be more or less academic to me today;-)  

my typical usage is

      tar zdQf tool-sources.tar.gz 

which shows "exactly" the relevant changes/filenames to me...


any comments or takers?



thanks,

Harald Koenig
