man yum  :)

 update If run without any packages, update will update every currently 
installed package.  If one or more packages are  specified,
              Yum  will  only  update the listed packages.  While 
updating packages, yum will ensure that all dependencies are satisfied.
              If no package matches the given package name(s), they are 
assumed to be a shell glob and any matches are then installed.

              If the --obsoletes flag is present yum will include 
package obsoletes in its calculations - this makes it better  for  dis-
              tro-version changes, for example: upgrading from somelinux 
8.0 to somelinux 9.

              Implemented  so  you could know if your machine had any 
updates that needed to be applied without running it interactively.
              Returns exit value of 100 if there are packages available 
for an update. Also returns a list of the pkgs to be  updated  in
              list format. Returns 0 and no packages are available for 

              Is the same as the update command with the --obsoletes 
flag set. See update for more details.
