`find -delete` 删除了所有内容

Question

我不太熟悉，find无意中删除了大量文件。我想知道是否有更有经验的人可以解释我哪里出错了。

我想清理所有的.DS_Store和._.DS_Store文件我的MacBook的Finder是barfing都在我的Raspbian桑巴份额。

• 我有一个硬盘驱动器连接到我的树莓派，我的主文件夹中有一些符号链接到安装点，因此-L.
• 某些文件夹归系统用户（例如 apache）所有，因此 sudo.

我运行了以下命令以确保它find针对的是正确的文件：

hydraxan@raspberry:~ $ sudo find -L . -maxdepth 255 -name \*DS_Store\*
./.DS_Store
./Downloads/USBHDD1/._.DS_Store
./Downloads/USBHDD1/.DS_Store
./Downloads/USBHDD1/backups/ALAC/._.DS_Store
./Downloads/USBHDD1/backups/ALAC/Jeff Van Dyck - Assault Android Cactus OST/._.DS_Store
./Downloads/USBHDD1/backups/ALAC/Jeff Van Dyck - Assault Android Cactus OST/.DS_Store
./Downloads/USBHDD1/backups/ALAC/.DS_Store
./Downloads/USBHDD1/backups/._.DS_Store
./Downloads/USBHDD1/backups/.DS_Store
./Downloads/USBHDD1/backups/OriginalMusic/._.DS_Store
./Downloads/USBHDD1/backups/OriginalMusic/.DS_Store
./Downloads/USBHDD1/backups/OriginalMusic/FLAC/.DS_Store
./Downloads/USBHDD1/backups/Storage/._.DS_Store
./Downloads/USBHDD1/backups/Storage/.DS_Store
./Downloads/OriginalMusic/._.DS_Store
./Downloads/OriginalMusic/.DS_Store
./Downloads/OriginalMusic/FLAC/.DS_Store
./Downloads/ALAC/._.DS_Store
./Downloads/ALAC/Jeff Van Dyck - Assault Android Cactus OST/._.DS_Store
./Downloads/ALAC/Jeff Van Dyck - Assault Android Cactus OST/.DS_Store
./Downloads/ALAC/.DS_Store

一切看起来都不错！

然后我添加了-delete标志以find删除它找到的文件：

hydraxan@raspberry:~ $ sudo find -L . -maxdepth 255 -delete -name \*DS_Store\*
find: cannot delete `./Documents': Not a directory
find: cannot delete `./Pictures': Not a directory
find: cannot delete `./Music': Not a directory

一旦我意识到它出于某种原因试图删除我的符号链接，我就猛击Ctrl+C并保存了大约一半的数据。

文档、图片和音乐是敬酒。它可能正在处理我几乎将所有内容都放入的巨大下载文件夹。

为什么要find删除所有这些文件？我是不是放-delete错地方了？

Answer 1

您的答案在find联机帮助页中。

删除选项在您的姓名过滤器之前处理。

       -delete
          Delete files; true if removal succeeded.  If the removal failed,
          an  error message is issued.  If -delete fails, find's exit sta?
          tus will be nonzero (when it eventually exits).  Use of  -delete
          automatically turns on the -depth option.

          Warnings:  Don't  forget that the find command line is evaluated
          as an expression, so putting -delete first will make find try to
          delete everything below the starting points you specified.  When
          testing a find command line that you later intend  to  use  with
          -delete,  you should explicitly specify -depth in order to avoid
          later surprises.  Because -delete  implies  -depth,  you  cannot
          usefully use -prune and -delete together.

您可以将删除选项移动为命令的最后一个

或者，你可以使用类似的东西

find /path -name "*pattern*" | xargs rm -f

或者

find /path -name "*pattern*" -exec rm -f {} \;
