Redis GETRANGE command is used to get the substring of the string value stored at the key, determined by the offsets start and end (both are inclusive). Negative offsets can be used in order to provide an offset starting from the end of the string.
The function handles out of range requests by limiting the resulting range to the actual length of the string.
Return Value
Simple string reply.
