Linux下批量ping某個網段ip的腳本

 

比如現在需要對172.16.50.0/24網段的ip進行檢查，檢查哪些ip現在被占用，哪些ip沒有被占用，可以通過ping命令來檢查，腳本如下:

[root@uatdns01 opt]# vim /opt/ping.sh 
#!/bin/bash
. /etc/init.d/functions
for var in {1..254};
do
ip=172.16.50.$var
ping -c2 $ip >/dev/null 2>&1
if [ $? = 0 ];then
action "$ip" /bin/true
else
action "$ip" /bin/false
fi
done

[root@uatdns01 opt]# chmod 755 /opt/ping.sh
[root@uatdns01 opt]# sh /opt/ping.sh

獲取172.16.60.0/24網段可用ip的shell腳本
[root@ansible-server ~]# cat ip_ping.sh 
#!/bin/bash 
ip=1 
while [ $ip != "254" ]; do 
ping 172.16.60.$ip -c 2 | grep -q "ttl=" && echo "172.16.60.$ip yes" || echo "172.16.60.$ip no" 
ip=`expr "$ip" "+" "1"` 
done 

執行:
[root@ansible-server ~]# sh ip_ping.sh
172.16.60.1 yes
172.16.60.2 no
172.16.60.3 no
.............
172.16.60.24 yes
172.16.60.25 yes
172.16.60.26 no
.............

如果只打印可用ip, 則腳本修改如下:
[root@ansible-server ~]# cat ip_ping.sh
#!/bin/bash 
ip=1 
while [ $ip != "254" ]; do 
ping 172.16.60.$ip -c 2 | grep -q "ttl=" && echo "172.16.60.$ip yes" || echo "172.16.60.$ip no" >/dev/null 2>&1
ip=`expr "$ip" "+" "1"` 
done 

執行:
[root@ansible-server ~]# sh ip_ping.sh
