自动删除文件/文件夹 [英] Automatically Delete Files/Folders

问题描述

有什么方法可以用很少的R命令行自动删除所有文件或文件夹? 我知道unlink()或file.remove()函数，但是对于那些函数，您需要定义一个字符向量，其中包含要删除的文件的所有名称.我正在寻找一些列出特定路径(例如'C:/Temp')中的所有文件或文件夹，然后删除具有特定名称(无论其扩展名如何)的所有文件的东西.

Is there any way to automatically delete all files or folders with few R command lines? I am aware of the unlink() or file.remove() functions, but for those you need to define a character vector with exactly all the names of the files you want to delete. I am looking more for something that lists all the files or folders within a specific path (e.g. 'C:/Temp') and then delete all files with a certain name (regardless of its extension).

非常感谢您的帮助！

推荐答案

也许您只是在寻找file.remove和list.files的组合?也许像这样:

Maybe you're just looking for a combination of file.remove and list.files? Maybe something like:

do.call(file.remove, list(list.files("C:/Temp", full.names = TRUE)))

我想您可以使用grep或grepl将文件列表过滤到名称与特定模式匹配的文件列表，不是吗?

And I guess you can filter the list of files down to those whose names match a certain pattern using grep or grepl, no?
