本例以c类地址为例,如果是A类或者B类地址,将脚本稍作修改即可ipaddr=`/usr/sbin/ip a | grep $1 | grep inet | awk '{print $2}'` netmask=`echo ${ipaddr} | awk -F "/" '{print $2}'` if [ $netmask -eq 24 ];then subnets=`echo ${ipaddr} | awk -F "." '{print $1"."$2"."$3"."}'` acount=0 for i in `seq 1 25` do /usr/bin/ping ${subnets}${i} -c 2 > /dev/null if [ $? -eq 0 ];then echo "${subnets}$i is online" let count+=1 else echo "${subnets}$i is not online" fi done fi echo "There are $count hosts onlie"
执行脚本时需要加上参数(网卡的连接名,如ens33)
