I believe the command you are looking for is
yum check-update

Hello,
Does yum or yum utils (repoquery likely) give the ability to
non-interactively and easily (single command or short sequence of
commands) generate a list of available update packages plus any new
dependent packages which would be required to to successfully install
those update packages on a server? "yum list updates" or "repoquery -a
--pkgnarrow=updates" don't appear to do the dependency analysis and from
other threads it seems that using "yum list updates" non-interactively
is frowned on (screen scraping thread, etc.). And "yum updates" can't
properly be used non-interactively as there appears to be no "defaultno"
option to answering the install question even if I wanted to screen
scrape, etc.
I read this yum list thread which indicates need for "yum list updates
--with-dependencies", but I can't see that such functionality has been
implemented in either yum 2.x or 3.x:
https://lists.dulug.duke.edu/pipermail/yum/2004-August/004974.html
Perhaps such functionality is in repoquery but I missed it?
I currently use "up2date --dry-run" for patch auditing on RHEL3 and
RHEL4 servers so I can view ahead of patch time exactly what packages
are required in order to bring a server up to date relative to a set of
yum repositories. RedHat maintains an "up2date to yum" Rosetta stone of
sorts at http://kbase.redhat.com/faq/FAQ_80_11223.shtm but there is no
indication of a yum equivalent of "update --dry-run" on that page.
Thanks for any advice.
