使用'for'循环迭代目录中的所有文件

Question

如何使用for循环遍历目录中的每个文件？

如何判断某个条目是某个目录还是仅仅是一个文件？

Answer 1

这将列出当前目录中的所有文件(以及仅文件):

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

此外,如果您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

(谢谢@agnul)

Answer 2

迭代...

• ...当前目录中的文件: for %f in (.\*) do @echo %f
• ...当前目录中的子目录: for /D %s in (.\*) do @echo %s
• ...当前和所有子目录中的文件: for /R %f in (.\*) do @echo %f
• ...当前和所有子目录中的子目录: for /R /D %s in (.\*) do @echo %s

不幸的是,我没有找到任何方法同时迭代文件和子目录.

只需使用cygwin及其bash即可获得更多功能.

除此之外:您是否注意到,MS Windows的构建帮助是描述cmd命令行语法的重要资源？

Answer 3

FOR从命令行运行和批处理文件之间存在细微差别.在批处理文件中,您需要%在每个变量引用前放置两个字符.

从命令行:

FOR %i IN (*) DO ECHO %i

从批处理文件:

FOR %%i IN (*) DO ECHO %%i

Answer 4

要迭代每个文件,for循环将起作用:

for %%f in (directory\path\*) do ( something_here )

在我的情况下,我也想要文件内容,名称等.

这导致一些问题,我认为我的用例可能会有所帮助.这是一个循环,它从目录中的每个'.txt'文件中读取信息,并允许您对它执行某些操作(例如setx).

@ECHO OFF
setlocal enabledelayedexpansion
for %%f in (directory\path\*.txt) do (
  set /p val=<%%f
  echo "fullname: %%f"
  echo "name: %%~nf"
  echo "contents: !val!"
)

*限制:val <= %% f只会获取文件的第一行.

Answer 5

此for循环将列出目录中的所有文件.

pushd somedir
for /f "delims=" %%f in ('dir /b /a-d-h-s') do echo %%f
popd

"delims ="对于显示带有空格的长文件名非常有用....

'/ b"只显示名称,而不是大小日期等.

关于dir/a argument的一些事情.

• 任何使用"/ a"都会列出所有内容,包括隐藏和系统属性.
• "/ ad"只会显示子目录,包括隐藏目录和系统目录.
• "/ ad"参数使用"D"irectory属性消除内容.
• "/ adhs"会显示所有内容,但是带有'D'irectory,'H'idden'S'ystem属性的条目.

如果在命令行上使用此选项,请删除"%".

希望这可以帮助.

Answer 6

%1引用传入的第一个参数,不能在迭代器中使用.

试试这个:

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

这是我在代码中的注释。

我只是在温习混蛋技巧，所以请原谅任何明显的错误。

我尝试尽我所能编写一个一体化解决方案，并根据用户需要进行一些修改。

一些重要的注意事项：如果您只想处理根目录文件和文件夹，只需将变量更改recursive为即可。FALSE否则，它将遍历所有文件夹和文件。

在找到此参考文献之前，我无法获得使用绝对路径的 jop 答案：https ://ss64.com/nt/for_r.html

以下示例循环遍历由绝对路径指定的目录中的所有文件。

For /R C:\absoulte\path\ %%G IN (*.*) do (
  Echo %%G
)

Answer 9

for %1 in (*.*) do echo %1

Answer 10

要通过所有文件和文件夹重复，您可以使用

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

要仅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

哪里/s将给出整个目录树中无限深度的所有结果。/s如果要遍历该文件夹的内容而不是其子文件夹，则可以跳过

在迭代中实现搜索

要遍历特定命名的文件和文件夹，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

要遍历特定命名的文件夹/目录而不是文件，然后/AD在同一命令中使用

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