要求:写一个脚本判断某个网络内所有活动的IP地址.
实现脚本:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | #!/bin/bash #script_name: ipscan.sh file1= /root/scripts/uplist file2= /root/scripts/downlist if [ -e $file1 ] then rm -rf $file1 fi if [ -e $file2 ] then rm -rf $file2 fi for ((i=2;i<=254;i++)) do /bin/ping -c 1 192.168.3.$i >> /dev/null if [ $? - eq 0 ] then echo "192.168.3.$i is alive" >> /root/scripts/uplist else echo "192.168.3.$i is not alive" >> /root/scripts/downlist fi done |
脚本执行效果:
[root@zabbix scripts]# sh ipscan.sh &
[1] 20131
[root@zabbix scripts]# ps -ef|grep ipscan |grep -v grep
root 20131 15528 0 17:41 pts/1 00:00:00 sh ipscan.sh
[root@zabbix scripts]# pwd
/root/scripts
[root@zabbix scripts]# ls
downlist ipscan.sh uplist
#查看IP统计
[root@zabbix scripts]# cat uplist |wc -l
50
[root@zabbix scripts]# cat downlist |wc -l
203
