This command copies the value stored at the source
key to the destination
key.
By default, the destination
key is created in the logical database used by the
connection. The DB
option allows specifying an alternative logical database
index for the destination key.
The command returns zero when the destination
key already exists. The
REPLACE
option removes the destination
key before copying the value to it.
Examples
SET dolly "sheep"
COPY dolly clone
GET clone
