NAME

md_doc_help_kdb-sget - kdb-sget(1) -- Get the value of a key stored in the key database from a script kdb sget <path> <default-value>

Where path is the full path to the key and default-value is the value that should be printed if no value can be retrieved.

DESCRIPTION

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 arugments). This command will either print the value of the key it retrives or a default value that the user specifies.

EXAMPLES

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 get /example/key 'notfound'
