  • yum - Yellowdog Updater Modified

    DESCRIPTION

    yum is an interactive, automated update program which can be used for maintaining systems using rpm


    command is one of:

    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 ssumed
    to be a shell glob and any matches are then installed.

    update:
    Can take packages as arguments, upgrade is just like update
    except that it includes package obsoletes in its calculations -
    this makes it better for distro-version changes, for example:
    upgrading from somelinux 8.0 to somelinux 9. *deprecated* - this
    command may be removed in the future.

    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:
    Can take packages as arguments, upgrade is just like update
    except that it includes package obsoletes in its calculations -
    this makes it better for distro-version changes, for example:
    upgrading from somelinux 8.0 to somelinux 9. *deprecated* - this
    command may be removed in the future.

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

    list:
    Can be used to list various information about available pack-
    ages; more complete details are available in the List Options
    section below.

    provides:
    Can be 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:
    Can be 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. Takes the same file glob wild-
    cards as provides.

    info:
    can be 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 yup
    cache directory over time. More complete details can be found
    in the Clean Options section below.
