NAME

       yumdb - query and alter the Yum database

SYNOPSIS

       yumdb [command] [packages ...]

DESCRIPTION

       This  command  is  used  to  query and alter the yum database, which is a simple key value
       store used in conjunction with the rpm database. Any installed package can have  arbitrary
       data  in the yum database, however the main use case is to store extra data about packages
       as they are installed.

       yumdb commands are:

       yumdb get <key> [pkg-wildcard]...

       This command will get the value for the given key, limiting to any specified packages.

       yumdb set <key> <value> [pkg-wildcard]...

       This command will set the value for the given key, to the given  value,  limiting  to  any
       specified packages.

       yumdb del <key> [pkg-wildcard]...

       This command will delete the given key, limiting to any specified packages.

       yumdb rename <old-key> <new-key> [pkg-wildcard]...

       This  command  will  rename  the  given  old-key,  to  the  given new-key, limiting to any
       specified packages. If the old-key does not exist, nothing happens.

       yumdb rename-force <old-key> <new-key> [pkg-wildcard]...

       This command will rename the  given  old-key,  to  the  given  new-key,  limiting  to  any
       specified packages. If the old-key does not exist, new-key is deleted.

       yumdb copy <old-key> <new-key> [pkg-wildcard]...

       This  command will copy the given old-key, to the given new-key, limiting to any specified
       packages. If the old-key does not exist, nothing happens.

       yumdb copy-force <old-key> <new-key> [pkg-wildcard]...

       This command will copy the given old-key, to the given new-key, limiting to any  specified
       packages. If the old-key does not exist, new-key is deleted.

       yumdb search <key> <wildcard>...

       This command will search all packages for the given key, against any of the given wildcard
       values.

       yumdb exist <key> [pkg-wildcard]...

       This command will print any packages which have the given key, limiting to  any  specified
       packages.

       yumdb unset <key> [pkg-wildcard]...

       This  command  will  print  any  packages which do not have the given key, limiting to any
       specified packages.

       yumdb info [pkg-wildcard]...

       This command will display all the data stored in the  yumdb,  limiting  to  any  specified
       packages.

       yumdb sync [pkg-wildcard]...

       This command will add any missing data to the yumdb from the repositories, limiting to any
       specified packages. This is useful to run if you have had any  aborted  transactions  (and
       thus.  missing  yumdb  data).  Note that "yumdb sync" cannot know all the information that
       would have been put into the yumdb at the time.

       yumdb sync-force [pkg-wildcard]...

       This command will replace any data in the yumdb from the  repositories,  limiting  to  any
       specified packages.

EXAMPLES

       List all the packages which don't have a from_repo key/value:

              yumdb unset from_repo

       List all the packages which were installed as dependencies:

              yumdb search reason dep

WELL KNOWN KEYS

       Note  that  there  is  no limit to the number of keys that can be created or what they may
       contain (for installed packages only). However this is a list of well known keys, and what
       they store.

       checksum_data

       checksum_type

       These keys store the createrepo checksum, and it's type, of the available
       package yum installed. Note that these are used by "yum version" to calculate
       the rpmdb version.

       command_line

       This key stores the entire command line, of the yum command (if it was called).

       from_repo

       from_repo_revision

       from_repo_timestamp

       These keys take values from the available package yum installed, and store the
       repo id, it's revision and timestamp.

       reason

       This key stores either "user" or "dep", currently. To mark if the user requested
       the package to be installed, or if it was brought in automatically as a
       dependency. Note that this is kept over updates.

       releasever

       This key stores the value of releasever, when the package was installed.

       installonly

       If this attribute has the value "keep" then this package will not be
       removed automatically by the installonly process (and does not count towards
       the installonly_limit).
