 Note that this format is automatically used whenever more than one key is returned. For example, if you request a key that contains an array, all values in the array will be returned sequentially. Alternatively, if you pass multiple keys on the command line, they will be returned. The format can also be forced using the `-b` or `--bash` command line switch:
 
 ```shell
-$ ./bin/cake config_read.config_read -b Key.Name
