NAME

yumdb command

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 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 all the data stored in the yumdb, 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).

Sus à l'Isengard! L'Isengard fût-il encerclé et fermé
de portes de pierre;
L'Isengard fût-il fort et dur, froid comme la pierre et
nu comme l'os,
Nous partons, nous partons en guerre, pour tailler la pierre
et briser la porte;
Car fût et branche la brûlent à présent, la fournaise gronde --
nous partons en guerre!
Au pays des ténèbres au pas du destin, au roulement du tambour,
nous arrivons, nous arrivons;
A l'Isengard avec le destin nous arrivons!
Avec le destin nous arrivons, avec le destin nous arrivons!
