Using the double quote (") as a delimiter, the third key would be a comma (,)
(see below for an example)
"A","B","C","D","E",...
1"2"3"4"5"6"7"8"9"A"B...
And since your sort command is sorting only on the fifth key, all the commas
are already in order (unless there is a blank line in there somewhere). The
order of the re cords within a sorted group may or may not be guaranteed to
change.
Change your sort order from '-k3' to '-k2 -k4 -k6 -k8 -k10 -k12' to sort by
Vendor, Name, Version, Version-Release, Arch, Summary and see if that helps.

Although you may be correct on the need to sort the NAME field using -k4
instead of -k3 ***, the question was not about the sort order, but about
the *content* of the SUMMARY fields being different between multiple
runs against the same database information for the same package, i.e.
notice the difference in the summary fields for the same bash package
above.
*** and this seems to explain a different but MUCH less annoying
confusion.
Thanks for that bit of help.

What you are seeing is indeed odd. I see 'version 3.1' but not '3.2'
anywhere on the Summary line of bash. What is your kernel by the way?
uname -mr ?
Have you cleared yum cache? Not just running a 'yum clean all' but
emptying the /var/cache/yum directory ?

In my attempts to reproduce what you are seeing, I used 'yum info' a few times for the packages that were not on my systems. But in your case (pure rpm operations) yum cache will not be relevant. By the way I looked at both CentOS 5 and 6 but did not see any inconsistency. And the reason why I asked about the kernel version was because it was not clear which version/release of CentOS you are running. Sorry for the noise. I will shut up now.

I would have said you also seeing 'version 3.1.' is one of the very odd
things, but then I check the bash rpm in a repo and it has 'version
3.1.' in the 3.2-32.el5 rpm.

It takes days/weeks of collecting the data via cron.daily and (I think)
having a few updates/installs happen between some of the runs.
On the boxes where I see it more, I often run the data collection script
immediately following updates. I almost think there is some kind of rpm
housekeeping that gets done on a daily basis that could affect it, but I
can't figure out what it would be, because the rpm script in cron.daily
only dumps data (similar to what mine dumps) to /var/log/rpmpkgs... it
does not issue any rpm clean up commands. as I understand anacron, each
of the scripts should finish before anacron starts the next, so there
should not be any DB contention, between the rpm script and mine, I
would think.
At one time (in the mists of history, probably around RHEL 1|2) I
thought there was a daily rpm cleanup task, but I can't find it on Cent
5 systems.

That is my thought too.
But I don't know where rpm could be getting the different info.

I am on CentOS 5.

I think I know some of what is causing what is going on now...
After a little testing with a format string of
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{INSTALLTIME:date}"\n'
I found I got different results based on the LANG environment setting,
which led me to try it with the SUMMARY field too.
###start with a normally configured terminal
$ cd /to/your/CentOS/mirror/
$ locale |grep LANG
LANG=en_US.UTF-8
$ rpm -q \
--qf
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{SUMMARY}"\n' \
-p 5.7/os/i386/CentOS/bash-3.2-32.el5.i386.rpm
"CentOS","bash","3.2","3.2-32.el5","i386","The GNU Bourne Again shell
(bash) version 3.1."
#now change LANG to what I see from cron
$ export LANG=
$ locale |grep LANG
LANG=
$ rpm -q \
--qf
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{SUMMARY}"\n' \
-p 5.7/os/i386/CentOS/bash-3.2-32.el5.i386.rpm
"CentOS","bash","3.2","3.2-32.el5","i386","The GNU Bourne Again shell
(bash) version 3.2"
Why does a number in a text string change based on LANG?
and for added fun... look at an agg package from epel
$ export LANG=en_US.UTF-8
$ rpm -q --qf
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{SUMMARY}"\n' agg
"Fedora Project","agg","2.5","2.5-9.el5","i386","Anti-Grain Geometry"
$ export LANG=
$ rpm -q --qf
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{SUMMARY}"\n' agg
"Fedora Project","agg","2.5","2.5-9.el5","i386","Anti-Grain Geometry
graphical rendering engine"
Why does the string length change this dramatically based on LANG?
Well I guess I at least know what I need to do to the script to have it
be consistent.
I might even get around to filing a RH bug, because this does not seem
to me to be a correct behavior to me. does anyone here see these changes
as correct behavior (and why)?

###And even more fun... try compat-db
$export LANG= ;rpm -q --qf
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{SUMMARY}"\n' compat-db
"CentOS","compat-db","4.2.52","4.2.52-5.1","i386","The Berkeley DB
database library for Red Hat Linux 7.x compatibility."
$ export LANG=en_US.UTF-8 ;rpm -q --qf

{SUMMARY}"\n' compat-db
"CentOS","compat-db","4.2.52","4.2.52-5.1","i386","The Berkeley DB

Yep that seems a strange one.

There's a separate dictionary of translated text strings (called a catalog) for each language. Those translations are looked up and substituted for the default text based on the locale or language settings in the environment. If the number is stored in the catalog as part of the string, you could see this effect. It appears that either the catalogs have not been updated along with the packages that make reference to them (which would be a bug), or the updated catalogs have not been installed because they are part of a "language pack" that is not listed as a dependency of all the packages that refer to it (which likely is a deliberate optimization). ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
