Shell腳本測試服務是否能夠ping通

/ 1 / ping指令詳解

-d         ：使用Socket的SO_DEBUG功能；
-c<完成次數>：設置完成要求迴應的次數；
-f：極限檢測；
-i<間隔秒數>：指定收發信息的間隔時間；
-I<網絡界面>：使用指定的網絡界面送出數據包；
-l<前置載入>：設置在送出要求信息之前，先行發出的數據包；
-n         ：只輸出數值；
-p<範本樣式>：設置填滿數據包的範本樣式；
-q         ：不顯示指令執行過程，開頭和結尾的相關信息除外；
-r         ：忽略普通的Routing Table，直接將數據包送到遠端主機上；
-R         ：記錄路由過程；
-s<數據包大小>：設置數據包的大小；
-t         ：超時時間
-v         ：詳細顯示指令的執行過程。
-W         : 等待時間

/ 2 / 腳本

使用方式

運行腳本時統一定義每個IP的循環次數, 例如

sh test.sh 2

腳本中有整數驗證, 輸入非法字符腳本會停止並輸出

循環次數必須爲正整數！

無需輸入URL的版本

#!/bin/bash
ip_array=(
  www.baidu.com
  www.csdn.net
)

cycle_num=0
if [ $# -ge 1 ];then
  expr $1 + 0 &>/dev/null
  if [ $? -eq 0 ];then
    cycle_num=$1
  else 
    echo "循環次數必須爲正整數！"
  fi
else 
  cycle_num=10
fi
for ((i=0;i<${cycle_num};i++))
do
    for url in ${ip_array[@]}
    do 
      echo "--------------------------"
      ping -c 1 -W 5 $url
      if [ $? -eq 0 ];then
        echo "success url : ${url}" 
      else 
        echo "Unable to Ping pass ${url}"
      fi
      echo "--------------------------"
      echo ""
    done
done
