如何对所有“你想覆盖吗"说不?批处理文件复制中的提示? [英] How to say no to all "do you want to overwrite" prompts in a batch file copy?

问题描述

默认情况下，从命令提示符复制会提示您覆盖目标位置中已存在的文件.

By default, copying from the command prompt will prompt you to overwrite files that already exist in the target location.

您可以添加/Y"来表示全部同意"替换.

You can add "/Y" to say "Yes to all" replacements.

但是你怎么能对所有人说不"呢?

But how can you say "No to all" ?

换句话说，我想从一个目录中复制不已存在于目标中的所有内容.

In other words, I want to copy everything from one directory that does not already exist in the target.

我看到的最接近的东西是 XCOPY 参数，它只在特定的 mod-datetime 之后复制东西.

The closest thing I see is the XCOPY argument to only copy things after a specific mod-datetime.

推荐答案

除非有一种情况，您不想要复制自上次复制以来已更改的源中的现有文件，为什么在不指定日期的情况下不要将 XCOPY 与/D 一起使用?

Unless there's a scenario where you'd not want to copy existing files in the source that have changed since the last copy, why not use XCOPY with /D without specifying a date?
