使用變數進行 Ping

Question 1

set /p UserInputPath = Enter chosen PC: 
                    ^ This space is included in the name of the variable

所以你以一個名為的變數來結束%UserInputPath %

更好的利用

set /p "UserInputPath=Enter Chosen PC: "
ping "%UserInputPath%.store.domain.company.com"

Answer

set /p UserInputPath = Enter chosen PC: 
                    ^ This space is included in the name of the variable

所以你以一個名為的變數來結束%UserInputPath %

更好的利用

set /p "UserInputPath=Enter Chosen PC: "
ping "%UserInputPath%.store.domain.company.com"

Question 2

以下腳本有效，至少對我在 Win7 上是有效的。

@echo off
set /p name="Enter name:"
ping %name%.google.com

我們首先要求用戶輸入名稱，然後將其儲存在name變數中，並將其傳遞給ping（請參閱%name%）添加google.com（就像範例一樣！）。

Question 3

這是給您的一個精美的 bash 腳本。今天早些時候針對最初的問題將其破解，然後才意識到它適用於 Windows。考慮將其轉換為批次文件，但看起來很痛苦。讓我想起了在大學時編寫啟動腳本的經歷。

您需要使用 Powershell 或在某處啟動 *nix 主機。 Powershell v3 真的很不錯。實際上，您可以相當輕鬆地將其轉換為 powershell。

對此會有一些反對票，但誰在乎呢。有人會發現這個腳本很有用。至少你可以掠奪邏輯和正規表示式。

在 Debian 中測試。
