Cassandra auto keyspace operation using script

[祝海通]

In our Cassandra test for YCSB benchmark, we want to create column family
and drop keyspace with script automatically.
But I fount that in our script. /bin/cassandra-cli; connect localhost/9160;
show keyspace;  can not execute.
Using the "" does not work.
and Using echo "connnet localhost/9160; show keyspace "｜bin/cassandra-cli
It doesn't work too.
