SYNOPSIS

9       yumdb [command] [packages ...]
10

DESCRIPTION

12       This  command  is  used to query and alter the yum database, which is a
13       simple key value store used in conjunction with the rpm  database.  Any
14       installed  package can have arbitrary data in the yum database, however
15       the main use case is to store extra data about  packages  as  they  are
16       installed.
17
18       yumdb commands are:
19
20       yumdb get <key> [pkg-wildcard]...
21
22       This  command  will  get  the  value for the given key, limiting to any
23       specified packages.
24
25       yumdb set <key> <value> [pkg-wildcard]...
26
27       This command will set the value for the given key, to the given  value,
28       limiting to any specified packages.
29
30       yumdb del <key> [pkg-wildcard]...
31
32       This command will delete the given key, limiting to any specified pack‐
33       ages.
34
35       yumdb rename <old-key> <new-key> [pkg-wildcard]...
36
37       This command will rename the given old-key, to the given new-key,  lim‐
38       iting to any specified packages. If the old-key does not exist, nothing
39       happens.
40
41       yumdb rename-force <old-key> <new-key> [pkg-wildcard]...
42
43       This command will rename the given old-key, to the given new-key,  lim‐
44       iting to any specified packages. If the old-key does not exist, new-key
45       is deleted.
46
47       yumdb copy <old-key> <new-key> [pkg-wildcard]...
48
49       This command will copy the given old-key, to the given new-key,  limit‐
50       ing  to  any specified packages. If the old-key does not exist, nothing
51       happens.
52
53       yumdb search <key> <wildcard>...
54
55       This command will search all packages for the given key, against any of
56       the given wildcard values.
57
58       yumdb exist <key> [pkg-wildcard]...
59
60       This command will print any packages which have the given key, limiting
61       to any specified packages.
62
63       yumdb unset <key> [pkg-wildcard]...
64
65       This command will print any packages which do not have the  given  key,
66       limiting to any specified packages.
67
68       yumdb info [pkg-wildcard]...
69
70       This  command  will  all  the data stored in the yumdb, limiting to any
71       specified packages.

EXAMPLES

75       List all the packages which don't have a from_repo key/value:
76
77              yumdb unset from_repo
78
79       List all the packages which were installed as dependencies:
80
81              yumdb search reason dep

WELL KNOWN KEYS

85       Note that there is no limit to the number of keys that can  be  created
86       or what they may contain (for installed packages only). However this is
87       a list of well known keys, and what they store.
88
89       checksum_data
90
91       checksum_type
92
93       These keys store the createrepo checksum, and it's type, of the available
94       package yum installed. Note that these are used by "yum version" to calculate
95       the rpmdb version.
96
97       command_line
98
99       This key stores the entire command line, of the yum command (if it was called).
100
101       from_repo
102
103       from_repo_revision
104
105       from_repo_timestamp
106
107       These keys take values from the available package yum installed, and store the
108       repo id, it's revision and timestamp.
109
110       reason
111
112       This key stores either "user" or "dep", currently. To mark if the user requested
113       the package to be installed, or if it was brought in automatically as a
114       dependency. Note that this is kept over updates.
115
116       releasever
117
118       This key stores the value of releasever, when the package was installed.
119
120       installonly
121
122       If this attribute has the value "keep" then this package will not be
123       removed automatically by the installonly process (and does not count towards
124       the installonly_limit).
