NAME

       yum - Yellowdog Updater Modified   

SYNOPSIS

       yum [options] [command] [package ...]   

DESCRIPTION

       yum  is  an interactive, automated update program which can be used for        maintaining systems using rpm         command is one of:         * install package1 [package2] [...]         * update [package1] [package2] [...]         * check-update         * upgrade [package1] [package2] [...]         * remove | erase package1 [package2] [...]         * list [...]         * info [...]         * provides | whatprovides feature1 [feature2] [...]         * clean [ packages | headers | metadata | cache | dbcache | all ]         * makecache         * groupinstall group1 [group2] [...]         * groupupdate group1 [group2] [...]         * grouplist [hidden]         * groupremove group1 [group2] [...]         * groupinfo group1 [...]         * search string1 [string2] [...]         * shell [filename]         * resolvedep dep1 [dep2] [...]         * localinstall rpmfile1 [rpmfile2] [...]         * localupdate rpmfile1 [rpmfile2] [...]         * deplist package1 [package2] [...]         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 Options  section               below.          provides 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 Options section below.          shell  Is  used  to enter the ’yum shell’, when a filename is specified               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               enabled repositories will be used to resolve dependencies.          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               Produces  a  list  of all dependencies and what packages provide               those dependencies for the given packages.     

GENERAL OPTIONS

       Most command line options can be set using the  configuration  file  as        well  and  the descriptions indicate the necessary configuration option        to set.          -h, --help               Help; display a help message and then quit.         -y     Assume yes; assume that the answer to any question  which  would               be asked is yes.               Configuration Option: assume-yes         -c [config file]               Specifies the config file location - can take http, ftp urls and               local file paths.         -d [number]               Sets the debugging level to [number] -  turns  up  or  down  the               amount of things that are printed. Practical range: 0 - 10               Configuration Option: debuglevel         -e [number]               Sets the error level to [number] Practical range 0 - 10. 0 means               print only critical errors about which you must be told. 1 means               print  all  errors,  even ones that are not overly important. 1+               means print more errors (if any) -e 0 is good for cron jobs.               Configuration Option: errorlevel         -R [time in minutes]               Sets the maximum amount of time yum will wait before  performing               a command - it randomizes over the time.         -C     Tells  yum  to  run  entirely  from cache - does not download or               update any headers unless it has to  to  perform  the  requested               action.         --version               Reports the yum version number and exits.         --installroot=root               Specifies  an  alternative  installroot,  relative  to which all               packages will be installed.               Configuration Option: installroot         --enablerepo=repoidglob               Enables specific repositories by id or glob that have been  dis-               abled in the configuration file using the enabled=0 option.               Configuration Option: enabled         --disablerepo=repoidglob               Disables specific repositories by id or glob.               Configuration Option: enabled         --obsoletes               This  option  only  has  affect  for an update, it enables yum´s               obsoletes processing logic. For more information see the  update               command above.               Configuration Option: obsoletes         --exclude=package               Exclude  a  specific package by name or glob from updates on all               repositories.               Configuration Option: exclude         --noplugins               Run with all plugins disabled.               Configuration Option: plugins    

LIST OPTIONS

       The following are the ways which you can invoke yum in list mode.  Note        that  all list commands include information on the version of the pack-        age.          yum list [all | regexp1] [regexp2] [...]               List all available and installed packages.         yum list available [regexp1] [...]               List all packages  in  the  yum  repositories  available  to  be               installed.          yum list updates [regexp1] [...]               List  all  packages  with updates available in the yum reposito-               ries.          yum list installed [regexp1] [...]               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 [regexp1] [...]               List the packages installed on the system that are not available               in any yum repository listed in the config file.          yum list obsoletes [regexp1] [...]               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.          Specifying package names               All the list options mentioned above take file-glob-syntax wild-               cards or package names as arguments, for example yum list avail-               able foo* will list all available packages that match foo*.     

CLEAN OPTIONS

       The following are the ways which you can invoke yum in clean mode.          yum clean packages               Eliminate any cached packages from the system.  Note that  pack-               ages are not automatically deleted after they are downloaded.          yum clean headers               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.          yum clean all               Runs yum clean packages and yum clean headers as above.     

MISC

       Specifying package names               A  package can be referred to for install,update,list,remove etc               with any of the following:                name               name.arch               name-ver               name-ver-rel               name-ver-rel.arch               name-epoch:ver-rel.arch               epoch:name-ver-rel.arch                For example: yum remove kernel-2.4.1-10.i686     

PLUGINS

       Yum can be extended through the use of plugins. A plugin  is  a  Python        ".py"  file  which  is installed in one of the directories specified by        the pluginpath option in yum.conf. For a plugin to work, the  following        conditions must be met:         1.  The plugin module file must be installed in the plugin path as just        described.         2. The global plugins option in /etc/yum.conf must be set to ‘1’.         3. A configuration file for the plugin must exist  in  /etc/yum/plugin-        conf.d/<plugin_name>.conf and the enabled setting in this file must set        to ‘1’. The minimal content for such a configuration file is:                [main]               enabled = 1         See the yum.conf(5) man page for more  information  on  plugin  related        configuration options.
