for循环比较ip是否可用，并通过scp协议传输文件

touch ip.txt res.txt
for i in `seq 1 100`  
 do 
 sleep 3
  ping  -c 1 10.10.1.$i > /dev/null 2>&1 
    if [ $? -eq 0 ]
     then
       echo "${i} ping OK" >> res.txt
       echo "10.10.1.$i" >> ip.txt
     else
       echo "${i} ping NOTOK" >> res.txt
    fi
 done
for i in `cat ip.txt`
 do
  ssh root@$i rm /etc/*
  scp file.zip root@$i:/etc
  ssh root@$i unzip /etc/file.zip
 done
