사용 예시 :

function removectn {
  sudo docker ps -a | grep -v 'CONTAINER' > statusctn.txt
  if [ -n "$(cat statusctn.txt)" ];then
    dialog --radiolist "container list" 20 150 4\
    $(while read line
      do
        echo "$line OFF" | gawk '{print $1, $(NF-1), $NF}'
      done < statusctn.txt)\
    2>deletecnt.txt
    dialog --infobox "removing container $(cat deletecnt.txt)" 5 30 ; sleep 1
    docker rm -f $(cat deletecnt.txt)
  else
    dialog --infobox "no container" 5 30; sleep 1
  fi
}

위 코드는 --radiolist를 이용하여 container 목록들을 보여주는 화면을 구성한 것이다.
