docker_multiple_exec.sh

function docker_exe {

        d=($(docker ps | grep -v fluentd | grep -v nginx | grep befit | awk '{print $1}'))
        for m in ${d[@]}    
         do
                docker exec -it $m $1                                                                                                                                                    
        done
