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.
