windows 使用windows cmd递归删除0KB文件

Recursively delete 0KB files using windows cmd

提问by crodjer

I have some process which creates some files of 0KB size in a directory and its sub-directories.
How can I delete the files from the file system using the windows command prompt?
Any single command or a script that will do the task will work.

我有一些进程可以在目录及其子目录中创建一些 0KB 大小的文件。
如何使用 Windows 命令提示符从文件系统中删除文件？
将执行该任务的任何单个命令或脚本都将起作用。

我只能运行简单的 cmd 命令和脚本，在访问受限的远程机器上工作。

1. Iterate recursively over the files:

   for /r %F in (*)
   

2. Find out zero-length files:

   if %~zF==0
   

3. Delete them:

   del "%F"
   

1. 递归遍历文件：

   for /r %F in (*)
   

2. 找出零长度文件：

   if %~zF==0
   

3. 删除它们：

   del "%F"
   

Putting it all together:

把它们放在一起：

for /r %F in (*) do if %~zF==0 del "%F"

If you need this in a batch file, then you need to double the %:

如果您需要在批处理文件中使用它，则需要将以下内容加倍%：

for /r %%F in (*) do if %%~zF==0 del "%%F"

Note:I was assuming that you meant files of exactly 0 Bytes in length. If with 0 KB you mean anything less than 1000 bytes, then above ifneeds to read if %~zF LSS 1000or whatever your threshold is.

注意：我假设您的意思是长度恰好为 0 字节的文件。如果 0 KB 意味着小于 1000 字节，那么上面if需要读取if %~zF LSS 1000或无论您的阈值是多少。

@echo off
setLocal EnableDelayedExpansion
for /f "tokens=* delims= " %%a in ('dir/s/b/a-d') do (
if %%~Za equ 0 del "%%a"
)

Found at : link textseems to work, with one caveat: It won't delete files with names containing spaces. There may be a work-around, but I'm afraid batch is not my forte.

发现于：链接文本似乎有效，但有一个警告：它不会删除名称包含空格的文件。可能有一个解决方法，但恐怕批处理不是我的强项。

This works fine when a typo is corrected. The problem was a missing tilde (~) e.g., del "%%a" needs to be del "%%~a"

更正错别字后，这可以正常工作。问题是缺少波浪号 (~) 例如，del "%%a" 需要是 del "%%~a"

This will indeed delete files with spaces in the name because it encloses the token in "double quotes" - an alternate method would be to use 'short name' as shown in the second example [ %%~sa

这确实会删除名称中带有空格的文件，因为它将标记括在“双引号”中 - 另一种方法是使用“短名称”，如第二个示例 [ %%~sa

@echo off setLocal EnableDelayedExpansion for /f "tokens=* delims= " %%a in ('dir/s/b/a-d') do ( if %%~Za equ 0 del "%%~a" )

@echo off setLocal EnableDelayedExpansion for /f "tokens=* delims=" %%a in ('dir/s/b/a-d') do ( if %%~Za equ 0 del "%%~a" )

@echo off setLocal EnableDelayedExpansion for /f "tokens=* delims= " %%a in ('dir/s/b/a-d') do ( if %%~Za equ 0 del %%~sa )

@echo off setLocal EnableDelayedExpansion for /f "tokens=* delims=" %%a in ('dir/s/b/a-d') do ( if %%~Za equ 0 del %%~sa )

You can try find.exe from the UnxUtils.

您可以从UnxUtils尝试 find.exe 。

find . -type f -empty -delete
