When I tried to connect to server using command 'bin/zkCli.sh -server', I got the below screen. But there is no [zkshell] prompt as mentioned on Getting started Guide.

I typed help on file line of the above screenshot, but, no response.

Please let me know if I am doing something wrong there.

Thanks in advanced.
