在Mac OS下通过shell script做ping循环测试

系统环境：

操作系统： MAC OS

   一个有意思，且有用的系统维护脚本，通过shell script 测试网络主机的连通性：

[tiany@localhost ~]$cat ping.sh

#!/bin/bash

for i in `seq 254`

do

ip=192.168.1.$i

ping -c1 $ip >/dev/null 2>&1

 [ $? -eq 0 ] && echo "$ip is alive" || echo "$ip is not alive"

done

[tiany@localhost ~]$sh ping.sh

192.168.1.1 is alive

192.168.1.2 is not alive

192.168.1.3 is not alive

192.168.1.4 is not alive

192.168.1.5 is not alive

192.168.1.6 is not alive

另转：

用shell脚本实现ping网段中的所有主机:

#!/bin/sh
# ping all host
# edit by www.jbxue.com
# find from /etc/hosts for host info,and filter IP address
cat /etc/hosts | grep -v ^# |grep -v ^$ | while read LINE
do
  for M in `awk '{print $1}'`
   do
     if ping -w 1 -c 1 $M | grep "100%" >/dev/null  
     then
         echo "$M is down"
     else
         echo "$M is up"
     fi
  done
done
