GETRANGE

Synopsis

GETRANGE key start end

This command fetches a substring of the string value that is associated with the given key between the two given offsets start and end. If an offset value is positive, it is counted from the beginning of the string. If an offset is negative, it is counted from the end. If an offset is out of range, it is limited to either the beginning or the end of the string.

  • If key does not exist, (null) is returned.
  • If key is associated with a non-string value, an error is raised.
