编写脚本，使用for和while分别实现192.168.0.0/24网段内，地址是否能够ping通，若ping通则输出"success!"，若ping不通则输出"fail!"

for循环:

#!/bin/bash
#
NetId=192.168.0.
for HostId in {1..254};do
{
    if /bin/ping -c 1 -W 1 $NetId$HostId > /dev/null;then
        echo "$NetId$HostId lived,Ping Test Successed"
    else
        echo "$NetId$HostId not lived,Ping Test Failed"
    fi

} &
done
wait

while 循环：

#!/bin/bash
#
NetId=192.168.0.
declare -i HostId=1
while [ $HostId -le 254 ];do
{
        /bin/ping -c 1 -W 1 $NetId$HostId > /dev/null
        if [ $? -eq 0 ];then
                echo "$NetId$HostId lived,Ping Test Successed"
        else
                echo "$NetId$HostId not lived,Ping Test Failed"
    fi
} &
    let HostId++
done
wait
