 )

 function wait()
 {
    echo -n '3秒后，执行该操作'；
    for ((i=0; i<3; i++))
    do
    echo -n ".";sleep 1
 done
 echo
 }

 function check_url(){
   set -x
     wait
   set +x
     echo 'check url...'
     for ((i=0; i<${#url_list[*]}; i++))
     do
     #HTTP/1.1 200 OK
     judge=($(curl -I -s ${url_list[$i]}|head -1|tr "\r" "\n"))
     if [[ "${judge[1]}" == '' && "${judge[2]}"=='OK' ]]
     then
     action "${url_list[$i]}" /bin/true
  else
     action "${url_list[$i]}" /bin/false
     fi
     done
     }
  check_url
