NAME

       md_doc_help_kdb-sgetkdb-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'
