Top Forums Shell Programming and Scripting Need help with pattern matching to list missing packages Post 302968388 by RudiC on Wednesday 9th of March 2016 03:16:23 AM

Why don't you yum list all installed packages and then check against your list? Would have the advantage running yum just once instead of once per package.

NAME
yum-cron - an interface to convieniently call yum from cron SYNOPSIS
yum-cron [config-file] DESCRIPTION
yum-cron is an alternate interface to yum that is optimised to be convenient to call from cron. It provides methods to keep repository metadata up to date, and to check for, download, and apply updates. Rather than accepting many different command line arguments, the dif- ferent functions of yum-cron can be accessed through config files. config-file is used to optionally specify the path to the configuration file to use. If it is not given, the default configuration file will be used. It is useful to be able to specify different configuration files for different use cases. For example, one configuration file might be set to update the repository metadata, and a line could be added to the crontab to run yum-cron frequently using this file. Then, another configuration file might be set to install updates, and yum-cron could be run from cron using this file just once each day. FILES
/etc/yum/yum-cron.conf /etc/yum/yum-cron-hourly.conf SEE ALSO
yum (8) AUTHORS
See the Authors file included with this program. BUGS
There of course aren't any bugs, but if you find any, you should email the mailing list, yum@lists.baseurl.org, or consult bugzilla. Nick Jacek yum-cron(8)
