Usage of ./redis-memory-analysis-darwin-amd64:
-ip string
The host of redis (default "127.0.0.1")
-password string
The password of redis (default "")
-port uint
The port of redis (default 6379)
-rdb string
The rdb file of redis (default "")
-prefixes string
The prefixes list of redis key, be split by '//', special pattern characters need to escape by '\' (default "#//:")
