Yum: What "Package Group" can provide a package?

stefanlasiewski · 10-08-2009, 06:55 PM

Yum supports the idea of "Package groups". Here's a listing of available groups on my RHEL5.4 system, after a vanilla installation:

Code:

[root@host1 ~]# yum grouplist
Loaded plugins: rhnplugin, security
Setting up Group Process
Installed Groups:
   Editors
   Legacy Network Server
   Mail Server
   Network Servers
   System Tools
Available Groups:
   Administration Tools
   Authoring and Publishing
   DNS Name Server
   ...
   ...

Is there a way to tell which Package Groups will provide a particular individual package?

For example, "emacs" is provided by the "Editor" package group, the "Development Environment" package group, and possibly others. I'm looking for a theoretical command like "yum groupinfo-whatprovides emacs"?

Here's what I am doing right now, to query all of the package groups for the 'httpd' package. This is a little clunky, and I was looking for a simpler method.

Code:

[root@host1 ~]# yum grouplist >/tmp/yum.grouplist
[root@host1 ~]# cat /tmp/yum.grouplist |while read GROUP; do echo GROUP=$GROUP; yum groupinfo "$GROUP" |grep -i httpd; done
GROUP=Editors
GROUP=Legacy Network Server
...
...
GROUP=Server Configuration Tools
   system-config-httpd
GROUP=Sound and Video
GROUP=Text-based Internet
GROUP=Web Server
   httpd
   httpd-manual
   httpd-suexec
GROUP=Windows File Server
GROUP=X Software Development
GROUP=X Window System

Thank you,

Well, I think you can eliminate the unwanted groups

Code:

yum grouplist >/tmp/yum.grouplist
for GROUP in `cat /tmp/yum.grouplist`
do 
    name=`yum groupinfo "$GROUP" |grep -i httpd`
    if [[ $? -eq  0 ]] # $? is status of last cmd in pipe ie matched
    then
        echo $GROUP = $name  
    fi
done

It's theoretically possible for the same pkg to turn up in many groups; don't know how often it happens.
Don't know if this page may inspire a different approach http://kbase.redhat.com/faq/docs/DOC-2531 ?

Thanks Chris.

It looks like RHEL does not support this feature. It's probably not a big deal, since it looks like RedHat has cleaned up the Package Groups in RHEL5. With RHEL4, there is more duplication.

Thanks again,
