What would be the “apt-cache show” equivalent on RHEL *without* requiring sudo/su?

Question

How can I query the local package cache of yum on RHEL (and derivatives) without requiring superuser privileges?

Note: I am not interested in running an update of the package cache up front. All I am interested in is to query what the local package cache already knows.

Edit: it turns out the problem wasn't the yum operation (search) itself in this case, but rather the fact that some of the files underneath /etc/yum.repos.d/ were unreadable due to some fellow admin putting them there this way.

Answer 1

That would be something like yum --cacheonly list. That (as all information querying commands) is not restricted to the superuser, special powers are only required for installation/erasing (in general, really modifying). See the yum(1) manpage, it details all the commands.
