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 depen-
dencies 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 distro-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 remov-
ing 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 description, summary,
packager and package name fields of an rpm. Useful 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 pack-
ages; 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 direc-
tory 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 reposi-
tories will be used to resolve dependencies.
localupdate
Is used to update the system by specifying local rpm files. Only the speci-
fied 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 depen-
dencies 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]

configuration file using the enabled=0 option.
Configuration Option: enabled
--disablerepo=repoidglob

Configuration Option: enabled
--obsoletes
This option only has affect for an update, it enables yum´s obsoletes pro-
cessing logic. For more information see the update command above.

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 package.
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 repositories.
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 wildcards or
package names as arguments, for example yum list available 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 packages are not
automatically deleted after they are downloaded.
yum clean headers
Eliminate all of the files which yum uses to determine the remote availabil-
ity of packages. Using this option will force yum to download all the head-
ers 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/pluginconf.d/<plu-
gin_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.
