Returns @array-reply of keys from a full Redis command and their usage flags.
`COMMAND GETKEYSANDFLAGS` is a helper command to let you find the keys from a full Redis command together with flags indicating what each key is used for.
`COMMAND` provides information on how to find the key names of each command (see `firstkey`, [key specifications](/topics/key-specs#logical-operation-flags), and `movablekeys`),
but in some cases it's not possible to find keys of certain commands and then the entire command must be parsed to discover some / all key names.
You can use `COMMAND GETKEYS` or `COMMAND GETKEYSANDFLAGS` to discover key names directly from how Redis parses the commands.
Refer to [key specifications](/topics/key-specs#logical-operation-flags) for information about the meaning of the key flags.
@return
@array-reply: list of keys from your command.
Each element of the array is an array containing key name in the first entry, and flags in the second.
@examples
```cli
COMMAND GETKEYS MSET a b c d e f
COMMAND GETKEYS EVAL "not consulted" 3 key1 key2 key3 arg1 arg2 arg3 argN
COMMAND GETKEYSANDFLAGS LMOVE mylist1 mylist2 left left
```
