Bug 51650

Description of Problem:

Would very much appreciate an "apropos" query option to the command line
for rpm.  If I don't know the exact package name, finding it without
sorting through all packages can be a pain.

Adding a command line option to help find the right package would be very
useful.  I propose the -A/--apropos query option, to take a search term
that will be searched against all known packages.

Without --apropos:

   "Hm, where is samba?"
   % rpm -q samba
   package samba not installed
   % rpm -q --whatprovides samba
   no package provides samba
   % rpm -q --file samba
   error: file samba: file not found
   % rpm -q -a | grep samba
   samba-client-2.0.10-2
   samba-common-2.0.10-2

   "Hm, which package provides smbmount?"
   % rpm -q --whatprovides smbmount
   no package provides smbmount
   % rpm -q --file smbmount
   error: file smbmount: file not found
   % which smbmount
   /usr/bin/smbmount
   % rpm -q --file /usr/bin/smbmount
   samba-client-2.0.10-2

With --apropos:

   % rpm -qA samba
   samba-client-2.0.10-2
   samba-common-2.0.10-2

   % rpm -qA smbmount
   samba-client-2.0.10-2

Additional Information:

The simplest form would be to just make it work like "rpm -q -a | grep %1",
but that would only help if the word you're looking for was a part of the
package name.  I suggest that --apropos match against the package names,
the provides (and virtual provides), and the filename lists, and returns
the matched package names, as shown in the examples above.

[Got suggestion from irc.linux.org #redhat that Jeff Johnson may be a
suitable party for this idea.]
