CentOS - May 2006 - Trying to find packages that depend on package X.

Quick search in bout "man yum" and "man rpm" shows how to
find what
package X depends upon, but not what depends upon package X. Of course,
we could get a deplist for everything but I'm *guessing* that take more
overhead and grep too.

"yum remove" tells us. Then we just have to remember to say "No,
don't
remove". Am I missing something... like I missed that big Google box on
the archives?

Anyway, if I haven't overlooked something, I was thinking that this
might be a good enhancement request for yum's buglist. Do like remove
but skip making us reliably answer "no".

OK. Did I miss something? Is this a feature that others would find
handy? Should I get it on a yum bug list?

Thx,
-- 
Bill

Just needs a little magic:

rpm -q --provides PACKAGE_NAME | sed 's/^/"/;s/\([^[:space:]]\)
*$/\1"/' | xargs rpm -q --whatrequires | grep -v -E '^no
package'

ex:
rpm -q --provides exim | sed 's/^/"/;s/\([^[:space:]]\)
*$/\1"/' | xargs rpm -q --whatrequires | grep -v -E '^no
package'
