Windows 命令队列？

Question 1

最简单的方法是编写一个批处理文件来执行您想要的操作，例如打开记事本并复制以下内容：

@echo off
echo Starting batch script
copy c:\temp\*.* c:\temp2\*.*
del c:\temp2\test.exe
echo all file operations complete

接下来，将其保存为 .bat 格式，然后双击或进入命令提示符并输入其名称即可运行它。您在其中写入的所有操作都将按顺序处理。

Question 2

不久前我写了一个名为的小批处理脚本QSTART。也许它会有所帮助。

它允许您（理论上）创建和执行任何 BATCH 命令的队列。队列是存储在%TEMP%目录中的纯文本文件。

这是一个非常简单的脚本，我在备份时用它来排队 zip 命令。

我没有做太多调试，因此请随意纠正任何现有的错误。我不能 100% 确定它是否能正确处理每个 BATCH 命令字符串，但它应该适合简单的任务。

重要。每个排队的命令都按原样执行。脚本不会检查任何错误，但循环ERRORLEVEL内的简单验证FOR可以解决该问题。

另外，我不是专业的程序员，并且知道脚本有点混乱（即，我不知道运行排队命令的任何其他方法；内置START命令有时对我来说不起作用）。

脚本末尾有帮助和一些示例。使用QSTART不带参数的命令可显示它。

@echo OFF
