       Unless the --help or -h option is given, one of the above commands must
       be present.


       install

              Is  used  to install the latest version of a package or group of
              packages while ensuring 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.


       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.


       check-update

              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 update.


       upgrade

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


       remove
 or erase

              Are  used  to  remove  the specified packages from the system as
              well as removing any packages which depend on the package  being
              removed.


       list
   Is  used  to  list various information about available packages;
              more complete details are available in the List

 or whatprovides

              Is used to find out which package provides some feature or file.
              Just use a specific name or a file-glob-syntax wildcards to list
              the packages available or installed that provide that feature or
              file.


       search
 Is used to find any packages matching a string in  the  descrip-
              tion,  summary, packager and package name fields of an rpm. Use-
              ful for finding a package you do not know by name  but  know  by
              some word related to it.


       info
   Is  used  to  list  a  description and summary information about
              available packages; takes the same  arguments  as  in  the  List

              Options
 section below.


       clean
  Is  used  to clean up various things which accumulate in the yum

              cache directory over time.  More complete details can  be  found
              in the Clean

              the contents of that file is executed in  yum  shell  mode.  See
              yum-shell(8)
 for more info


       resolvedep

              Is  used  to list packages providing the specified dependencies,
              at most one package is listed per dependency.


       localinstall

              Is used to install a set of local rpm  files.  If  required  the

       localupdate

              Is used to update the system by specifying local rpm files. Only
              the specified rpm files of which an  older  version  is  already
              installed  will  be  installed, the remaining specified packages
              will be ignored.  If required the enabled repositories  will  be
              used to resolve dependencies.


       deplist

       age.


       yum
 list
 [all
 |
 regexp1]
 [regexp2]

       Specifying
 package
 names

              All the list options mentioned above take file-glob-syntax wild-

CLEAN OPTIONS

       The following are the ways which you can invoke yum
 in clean mode.

              Eliminate  all  of  the  files  which  yum uses to determine the
              remote availability of packages. Using this  option  will  force
              yum to download all the headers the next time it is run.
