How to list all the topics in all groups with total count of messages in each topic with single kafka command?

I'm trying to list all topics from all group ids with total number of messages in each topic but couldn't find such command anywhere. Tried the below 2 commands but expecting the results of the below commands in a single command. Please help.

Command 1:(To list all topics in Kafka server)

bin/kafka-topics.sh --list --zookeeper localhost:2181

Command 2:(To know the count of total messages in a topic in Kafka server)

bin/kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list 0.0.0.0:6667 --topic topicname --time -1

I have never heard of a kafka command that can do what you want. However, you can achieve this with basic shell scripting. This command should do the job :

./bin/kafka-topics.sh --zookeeper localhost:2181 --list | while read x; do ./bin/kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list localhost:9092 --topic $x --time -1; done

Tested with kafka 0.10.2 running on Linux.
