Update From The Command Line With Rug - Novell LINUX ENTERPRISE DESKTOP 10 SP2 - DEPLOYMENT GUIDE 08-05-2008 Deployment Manual

8.14 Update from the Command Line
with rug
rug uses the zmd daemon to install, update, and remove software according to the
commands given. It can either install software from local files, or from servers. You
may use one or more remote servers, known as services. Supported services are mount
for local files, and yum or ZENworks for servers.
rug sorts software from services into catalogs (also known as channels), which corre-
spond to groups of similar software. For example, one catalog might contain software
from an update server as well as software from a third-party software vendor. You are
able to subscribe to individual catalogs in order to control the display of available
packages and prevent the accidental installation of unwanted software. Operations
usually are performed only on software from catalogs to which you are subscribed.
8.14.1 Obtaining Information from rug
rug provides a wide range of useful information. It allows you to check the status of
zmd, view registered services and catalogs, or see information about available patches.
If the zmd is not used for a certain period of time, it can be switched to sleep mode. To
check the zmd status and reactivate the daemon, use rug ping. This command wakes
zmd up and logs its status information.
To see your registered services, use rug sl, and to see which services are supported
on your system, use rug st.
To check for new patches, use rug pch. To get information about a patch, enter
rug patch-info patch.
8.14.2 Subscribing to rug Services
By default, a newly installed system is subscribed to several services. To add a new
service, use rug sa URI service_name. Replace service_name with a
meaningful and unique string that identifies the new service.
