如何在redis中重命名具有匹配模式的键

Question

I have 1000 of keys like :

alpha_123_dubai_2015

wherein I want to rename the key names as :

live_123_dubai_2015

I am new to Redis found some suggestions below :

redis 127.0.0.1:6379> RENAME key1 key2

But I don't want to specify whole key name and just want to execute similar query to below sql query in redis :

update tablename set new_key = '2' where key like '%1%' That is in above scenario we just want to replace the value 1 of key1 with value 2 and new key formed will look like key2

Kindly suggest.
