+ * off          Disable the user
+ * +<command>   Allow the execution of that command
+ * -<command>   Disallow the execution of that command
+ * +@<category> Allow the execution of all the commands in such category
+ *              with valid categories being @set, @sortedset, @list, @hash,
+ *                                          @string, @bitmap, @hyperloglog,

+ *              The special category @all means all the commands.
+ * +<command>|subcommand    Allow a specific subcommand of an otherwise
+ *                          disabled command. Note that this form is not
+ *                          allowed as negative like -DEBUG|SEGFAULT, but
+ *                          only additive starting with "+".
+ * ~<pattern>   Set a pattern of keys that can be mentioned as part of
+ *              commands. For instance ~* allows all the keys. The pattern
+ *              is a glob-style pattern like the one of KEYS.
+ * ><password>  Add this passowrd to the list of valid password for the user.
+ *              For example >mypass will add "mypass" to the list.
+ * <<password>  Remove this password from the list of valid passwords.
+ * resetpass    Flush the list of allowed passwords.
