How to do something to each file in a directory with a batch script
提问by Brian R. Bondy
How do you iterate over each file in a directory with a .bat or .cmd file?
如何使用 .bat 或 .cmd 文件遍历目录中的每个文件？
For simplicity please provide an answer that just echoes the filename or file path.
为简单起见，请提供一个仅与文件名或文件路径相呼应的答案。

Command line usage:
命令行用法：
for /f %f in ('dir /b c:\') do echo %f
Batch file usage:
批处理文件使用：
for /f %%f in ('dir /b c:\') do echo %%f
Update: if the directory contains files with space in the names, you need to change the delimiter the for /fcommand is using. for example, you can use the pipe char.
更新：如果目录包含名称中带有空格的文件，则需要更改for /f命令使用的分隔符。例如，您可以使用管道字符。
for /f "delims=|" %%f in ('dir /b c:\') do echo %%f
Update 2: (quick one year and a half after the original answer :-)) If the directory name itself has a space in the name, you can use the usebackqoption on the for:
更新 2:(在原始答案后一年半很快:-)) 如果目录名称本身在名称中有空格，则可以使用以下usebackq选项for：
for /f "usebackq delims=|" %%f in (`dir /b "c:\program files"`) do echo %%f
And if you need to use output redirection or command piping, use the escape char (^):
如果您需要使用输出重定向或命令管道，请使用转义字符 ( ^)：
for /f "usebackq delims=|" %%f in (`dir /b "c:\program files" ^| findstr /i microsoft`) do echo %%f

Alternatively, use:
或者，使用：
forfiles /s /m *.png /c "cmd /c echo @path"
The forfiles command is available in Windows Vista and up.
forfiles 命令在 Windows Vista 及更高版本中可用。

Easiest method:
最简单的方法：
From Command Line, use:
从命令行，使用：
for %f in (*.*) do echo %f
From a Batch File (double up the % percent signs):
从批处理文件（将 % 百分号加倍）：
for %%f in (*.*) do echo %%f
From a Batch File with folder specified as 1st parameter:
从文件夹指定为第一个参数的批处理文件：
for %%f in (%1\*.*) do echo %%f

Use
用
for /r path %%var in (*.*) do some_command %%var
with:
和：
- path being the starting path.
- %%var being some identifier.
- *.* being a filemask OR the contents of a variable.
- some_command being the command to execute with the path and var concatenated as parameters.
- path 是起始路径。
- %%var 是一些标识符。
- *.* 是文件掩码或变量的内容。
- some_command 是将路径和 var 作为参数连接起来执行的命令。

Another way:
其它的办法：
for %f in (*.mp4) do call ffmpeg -i "%~f" -vcodec copy -acodec copy "%~nf.avi"

I had some malware that marked all files in a directory as hidden/system/readonly. If anyone else finds themselves in this situation, cd into the directory and run for /f "delims=|" %f in ('forfiles') do attrib -s -h -r %f.
我有一些恶意软件将目录中的所有文件标记为隐藏/系统/只读。如果其他人发现自己处于这种情况，请 cd 进入目录并运行for /f "delims=|" %f in ('forfiles') do attrib -s -h -r %f.
