Answers:
由于您的ip范围没有对称性,并且只有10个节点,因此建议您在文本文件中列出它们。我正在考虑包含该列表的文件list.txt
,其中每行包含一个IP列表,如下所示,
10.12.13.14
172.15.48.3
192.168.45.54
...
48.114.78.227
您可以使用此脚本,
#!/bin/bash
# Program name: pingall.sh
date
cat /path/to/list.txt | while read output
do
ping -c 1 "$output" > /dev/null
if [ $? -eq 0 ]; then
echo "node $output is up"
else
echo "node $output is down"
fi
done
要每隔30分钟更新一次节点的运行状态,请在crontab中使用,
*/30 * * * * /path/to/pingall.sh > /path/to/log.txt
log.txt的输出
$ cat /path/to/log.txt
Fri Jan 31 15:06:01 IST 2014
node 10.12.13.14 is up
node 172.15.48.3 is up
node 192.168.45.54 is up
...
node 48.114.78.227 is down
#!/bin/bash
while read hostname
do
ping -c 1 -t 1 "$hostname" > /dev/null 2>&1 &&
echo "Ping Status of $hostname : Success" ||
echo "Ping Status of $hostname : Failed"
done < host.txt
$ cat host.txt
host1.example.com
192.168.0.123
8.8.8.8
...
...
google.com
请参阅:http :
//www.thelinuxtips.com/2012/06/shell-script-to-ping-multiple-hosts/
检查此脚本。
#!/bin/bash
for i in `seq ${2} ${3}`
do
ping -c 1 ${1}.${i} > /dev/null 2>&1
if [ $? -eq 0 ]; then
echo "${1}.${i} responded."
else
echo "${1}.${i} did not respond."
fi
done
例如,要运行./script 192.168.1 0 10,它将把ips 192.168.1.0转换为192.168.1.10,如果ping正常,则echo响应,否则,则不响应。
注意:如果范围和IP始终相同,则可以用静态变量替换$ 1 $ 2 $ 3。
假设您有5个IP(仅用于减少答案),则可以使用
#!/usr/bin/bash
for i in xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxxx
do
ping -c 5 $i
done
注意:IP不能夹括号,IP之间不要逗号。
希望能有所帮助。

工作,将通知用户该工作结果的方法是必要的,或者您是否提出其他建议?
好
就这么简单:使用 parallel --gnu
命令,再您的命令。
