           Summary: zypper -q does not suppress all unwanted output
    Classification: openSUSE
           Product: openSUSE 11.1
           Version: Final
          Platform: Other

I wrote a cron script to check for updates via zypper. There should only be
output if there are updates available in order to send an eMail (if there is no
output cron will not send a mail).

For refreshing this works fine:
 zypper -q --non-interactive ref --service

But for listing updates this does not:
 zypper -q --non-interactive list-patches
There is a heading "Patches" and two newlines as output even if there are no
patches. Even if there were, I would have expected that the heading gets
suppressed as well.

Even filtering does not solve the problem:
 zypper -q --non-interactive list-patches | grep -v "^Patches$" | grep -v
"^\s*$"
The newlines contian some control sequences that pass the filter.

Please make sure that if "-q" is added to zypper that nothing is printed if the
result is empty, thanks.
