       yum list [all | glob_exp1] [glob_exp2] [...]
              List all available and installed packages.

       yum list available [glob_exp1] [...]
              List all packages  in  the  yum  repositories  available  to  be
              installed.

       yum list updates [glob_exp1] [...]
              List   all   packages   with   updates   available  in  the  yum
              repositories.

       yum list installed [glob_exp1] [...]
              List the packages specified by args.  If an  argument  does  not
              match  the  name  of an available package, it is assumed to be a
              shell-style glob and any matches are printed.

       yum list extras [glob_exp1] [...]
              List the packages installed on the system that are not available
              in any yum repository listed in the config file.

       yum list obsoletes [glob_exp1] [...]
              List  the packages installed on the system that are obsoleted by
              packages in any yum repository listed in the config file.

       yum list recent
              List packages recently added  into  the  repositories.  This  is
              often  not  helpful, but what you may really want to use is "yum
              list-updateinfo new" from the security yum plugin.
