kdb-sget(1) -- Get the value of a key stored in the key database from a script

kdb sget <key name> <default-value>

Where key name is the name of the key to retrieve and default-value is the value that should be printed if no value can be retrieved.

This command is used to retrieve the value of a key from within a script. When using the kdb tool in a script, the user should use the sget command in place of the kdb-get(1) command. The kdb-get(1) command should not be used in scripts because it may return an error instead of printing a value in certain circumstances. The sget command guarantees that a value will be printed (unless the user passes faulty arguments). This command will either print the value of the key it retrieves or a default value that the user specifies.

To get the value of a key from a script or return the value 0:
kdb sget user/example/key 0

To get the value of a key using a cascading lookup or return the value notfound:
kdb sget /example/key "notfound"
