kdb setmeta <key-name> <meta-name> <meta-value>
Where key-name
is the path to the key that the meta key is associated with, meta-name
is the name of the meta key the user would like to set the value of (or create), and meta-value
is the value the user wishes to set the meta key to.
This command allows the user to set the value of an individual meta key. If a key does not already exist and the user tries setting a meta key associated with it, the key will be created with a null value. There is some special handling for the meta data atime, mtime and ctime. They will be converted to time_t.
For cascading keys, the namespace will default to spec
, because that is the place where you usually want to set meta data.
