如何使用for循环遍历目录中的每个文件?

我如何判断某个条目是一个目录还是一个文件?


当前回答

%1是传入的第一个参数,不能在迭代器中使用。

试试这个:

@echo off
for %%i in (*.*) do echo %%i

下面是代码中的注释。

我只是在温习婊子技能,所以请原谅任何明显的错误。

我试着写一个all in one解决方案,尽我所能,在用户需要的地方做了一些修改。

一些重要注意事项:如果只希望处理根目录、文件和文件夹,只需将变量递归更改为FALSE。否则,它会检查所有文件夹和文件。

最欢迎C&C…

      rem echo    → %%~dp$dir:F    &rem searches the directories listed in the 'dir' environment variable and expands %%F to the fully qualified name of the first one found. If the environment variable name is not defined or the file is not found by the search, then this modifier expands to the empty string

      )
      )
    popd
    )
  )
echo/ & pause & cls

这将递归地列出当前目录及其子目录中的所有文件(仅是文件):

for /r %i in (*) do echo %i

此外,如果在批处理文件中运行该命令,则需要将%符号加倍。

for /r %%i in (*) do echo %%i

(感谢@agnul)

遍历您可以使用的所有文件和文件夹

for /F "delims=" %%a in ('dir /b /s') do echo %%a

若要只遍历所有文件夹而不遍历文件,则可以使用

for /F "delims=" %%a in ('dir /a:d /b /s') do echo %%a

其中/s将以无限深度给出整个目录树的所有结果。如果您想遍历该文件夹的内容而不是其子文件夹的内容,则可以跳过/s

在迭代中实现搜索

要遍历特定的命名文件和文件夹,您可以搜索名称并使用for循环进行迭代

for /F "delims=" %%a in ('dir "file or folder name" /b /s') do echo %%a

要遍历特定的命名文件夹/目录而不是文件,请在同一命令中使用/AD

for /F "delims=" %%a in ('dir "folder name" /b /AD /s') do echo %%a

在我的情况下,我必须删除临时文件夹下的所有文件和文件夹。这就是我最后做这件事的原因。我必须运行两个循环一个文件和一个文件夹。如果文件或文件夹名称中有空格,则必须使用" "

cd %USERPROFILE%\AppData\Local\Temp\
rem files only
for /r %%a in (*) do (
echo deleting file "%%a" ...
if exist "%%a" del /s /q "%%a"
)
rem folders only
for /D %%a in (*) do (
echo deleting folder "%%a" ...
if exist "%%a" rmdir /s /q "%%a"
)
