Linux下批量ping某个网段ip的脚本
比如现在需要对172.16.50.0/24网段的ip进行检查，检查哪些ip现在被占用，哪些ip没有被占用，可以通过ping命令来检查，脚本如下：
[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
