SREM

Synopsis

SREM key value [value ...]
This command removes one or more specified members from the set that is associated with the given key.

If the `key` does not exist, the associated set is an empty set, and the return value is zero.

If the `key` is associated with a value that is not a set, an error is raised.

If a specified `value` does not exist in the given set, that `value` is ignored and not counted toward the total of removed members.

Return value

Returns the total number of existed members that were removed from the set.
