本文提供了一种通过Shell脚本来批量检测特定网段内IP地址是否可达的方法。该脚本适用于快速查找空闲IP资源，支持对不同网段进行检测，并能够输出已用和未用IP地址。

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
172.16.50.1                                                [  OK  ]
172.16.50.2                                                [FAILED]
172.16.50.3                                                [FAILED]
172.16.50.4                                                [FAILED]
172.16.50.5                                                [FAILED]
.........
.........
172.16.50.99                                             [  OK  ]
172.16.50.100                                            [  OK  ]
172.16.50.101                                            [  OK  ]
172.16.50.102                                            [  OK  ]
172.16.50.103                                            [  OK  ]
172.16.50.104                                            [  OK  ]
172.16.50.105                                            [  OK  ]
172.16.50.106                                            [  OK  ]
172.16.50.107                                            [  OK  ]
172.16.50.108                                            [  OK  ]
172.16.50.109                                            [  OK  ]
172.16.50.110                                            [  OK  ]
172.16.50.111                                            [FAILED]
172.16.50.112                                            [  OK  ]

获取172.16.60.0/24网段可用ip的shell脚本
[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 

执行:
[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, 则脚本修改如下:
[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 

执行:
[root@ansible-server ~]# sh ip_ping.sh
172.16.60.1 yes
172.16.60.21 yes
172.16.60.22 yes
172.16.60.23 yes
172.16.60.24 yes
172.16.60.25 yes
172.16.60.31 yes
172.16.60.32 yes
172.16.60.33 yes
172.16.60.34 yes
172.16.60.35 yes
172.16.60.36 yes
172.16.60.37 yes

获取172.16.50.0/24, 172.16.51.0/24, 172.16.60.0/24 三个网段的可用ip
[root@ansible-server ~]# cat ip_ping.sh
#!/bin/bash 
ip=1 
while [ $ip != "254" ]; do 

ping 172.16.50.$ip -c 2 | grep -q "ttl=" && echo "172.16.50.$ip yes" || echo "172.16.50.$ip no" >/dev/null 2>&1
ip=`expr "$ip" "+" "1"` 

ping 172.16.51.$ip -c 2 | grep -q "ttl=" && echo "172.16.51.$ip yes" || echo "172.16.51.$ip no" >/dev/null 2>&1
ip=`expr "$ip" "+" "1"` 

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"`
