kdb-setmeta(1) Set the value of a meta key


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.
