通过批处理文件删除文件之前回显 [英] echo before deleting file through batch file

问题描述

我正在运行类似

for %j in (c:\user\data) do if not %j == Important del %i

以便除此文件外的所有文件都被删除.但是，重要的是，在运行此文件之前，我想确保脚本只会删除我要删除的文件，因此，我想查看文件在运行前是否受到影响，因此尝试使用回声为

so that all files get deleted except this one Important however, before I run this I wanted to make sure that script will only delete which I meant to hence, I wanted to see the files being affected before I run so I tried using echo as

for %i in ("c:\user\data") do echo %i

但是这似乎不起作用，我希望看到该目录中的所有文件，以便可以确定文件是否受到影响，但看不到任何东西，没有错误或任何东西.看起来CMD打开和关闭非常快.有人可以帮我吗..

but this does not seem working, I am expecting to see all the files in this directory so that I would be sure about the files being affected but I do not see anything, no error or anything. It just looks CMD opens and closes very fast. Can someone please help me..

推荐答案

您只需要根据您的条件引用目录的内容，而不仅仅是目录本身.从命令行:

You simply need to refer to the contents of the directory in your condition, rather than merely the directory itself. From command line:

for %i in (c:\user\data\*) do echo %i

如果要在批处理文件中执行此操作，则需要为循环变量添加双百分号:

And if you're doing it inside a batch file, then you need to add double percent signs for your loop variable:

for %%i in (c:\user\data\*) do echo %%i
