linux bash - 从另一个目录中删除一个目录中的所有文件

linux bash - remove all files which are in one directory from another directory

提问by Zulakis

I want to remove all files that exist in folder new-filesfrom another folder in linux using bash commands.

我想new-files使用 bash 命令从 linux 中的另一个文件夹中删除文件夹中存在的所有文件。

I need this for two things:

我需要这两个东西：

• I got some setup scripts which copy some pre-configured config files over. I would like to have the option to remove those files again
• Sometimes it happens that archives get unpacked into the root of your downloads directory and not into a subdir because the person packing the file put everything to the archives root

• 我得到了一些安装脚本，它们复制了一些预先配置的配置文件。我希望可以选择再次删除这些文件
• 有时会发生档案被解压到您的下载目录的根目录而不是子目录中，因为打包文件的人将所有内容都放在档案根目录中

What's the best way to do that?

最好的方法是什么？

Edit, to clarify:

编辑，澄清：

1. I got a folder with files called new-files.
2. Now I execute cp -r new-files/* other-directory/.
3. Lets say other-directory is not the directory I wanted to copy them to but it already contains other files so I can't just do rm other-directory/*.
4. I need to delete all folders which I accidently copied. How do I do that?

1. 我有一个文件夹，里面有一个名为new-files.
2. 现在我执行cp -r new-files/* other-directory/.
3. 让我们说 other-directory 不是我想将它们复制到的目录，但它已经包含其他文件，所以我不能只做 rm other-directory/*。
4. 我需要删除我不小心复制的所有文件夹。我怎么做？

You could use the following command:

您可以使用以下命令：

cd new-files ; find . -exec rm -rf path/to/other-directory/{} \;

It will list all the files that where copied from the new-filesdirectory (new-filesdirectory will not be taken in consideration). For each file, it will remove the copied version in other-directory.

它将列出从new-files目录中复制的所有文件（new-files目录不会被考虑在内）。对于每个文件，它将删除other-directory.

But you've to be careful, if a file in new-fileserase a file in other-directory, you won't be able to restore the old file using this method. You should consider to use a versioning system (like Gitfor example).

但是你要小心，如果一个文件new-files删除了一个文件other-directory，你将无法使用这种方法恢复旧文件。您应该考虑使用版本控制系统（例如Git）。

You can loop through the original dir new-files/and delete files with same name in the other-directory/:

您可以遍历原始目录new-files/并删除以下同名文件other-directory/：

for file in /new-files/*
do
   rm /other-directory/"$file"
done
