shell指令碼之ping測試

原理：使用shell指令碼執行一個ping命令。

1）變數destination_ip是目標主機的ip地址。 2）ping後的-c1參數代表的是本主機向目標主機發送的最多測試包數。 3）&>為重新導向 4）建立一個檔案，vi pingtest.sh，添加以下代碼1/2/3：

#!/bin/bashdestination_ip=192.168.109.2if ping -c1 $destination_ip &>/dev/nullthen echo "$destinaion_ip is online."elseecho "$destination_ip is offline."fi

2 . 代碼2

#!/bin/bash$destination_ipread -p "please inpur ip :" destination_ipif ping -c1 $destination_ip &>/test.txtthen echo "$destination_ip is online."else echo "$destination_ip is offline."fi

3 . 代碼3

#!/bin/bashif ping -c1 $1 &>/test.txtthen echo "$1 is online."else echo "$1 is offline."fi
