Get filename in batch for loop
提问by Murtaza Mandvi
I have the following For loop in a batch file:
我在批处理文件中有以下 For 循环：
for /R c:\test\src %%i IN (*.*) DO (
MOVE %%i C:\test\destination
ECHO %%i
exit
)
The result of the ECHO outputs the entire file path Ex: C:\Foldername\FilenameI need to ECHO out only the Filename.Is there a specific command which would give me the filename ? Thanks !
ECHO 的结果输出整个文件路径 例如：C:\Foldername\Filename我只需要 ECHO 出Filename。是否有特定的命令可以给我文件名？谢谢 ！

When Command Extensions are enabled (Windows XP and newer, roughly), you can use the syntax %~nF (where F is the variable and ~n is the request for its name) to only get the filename.
当启用命令扩展（Windows XP 和更新版本，大致）时，您可以使用语法 %~nF（其中 F 是变量，~n 是对其名称的请求）来仅获取文件名。
FOR /R C:\Directory %F in (*.*) do echo %~nF
should echo only the filenames.
应该只回显文件名。

or Just %~F will give you the full path and full file name.
或者 Just %~F 会给你完整的路径和完整的文件名。
For example, if you want to register all *.ax files in the current directory....
例如，如果要注册当前目录中的所有 *.ax 文件....
FOR /R C:. %F in (*.ax) do regsvr32 "%~F"
This works quite nicely in Win7 (64bit) :-)
这在 Win7（64 位）中非常有效:-)

I am a little late but I used this:
我有点晚了，但我使用了这个：
dir /B *.* > dir_file.txt
then you can make a simple FOR loop to extract the file name and use them. e.g:
然后你可以做一个简单的 FOR 循环来提取文件名并使用它们。例如：
for /f "tokens=* delims= " %%a in (dir_file.txt) do (
gawk -f awk_script_file.awk %%a
)
or store them into Vars (!N1!, !N2!..!Nn!) for later use. e.g:
或将它们存储到 Vars (!N1!, !N2!..!Nn!) 以备后用。例如：
set /a N=0
for /f "tokens=* delims= " %%a in (dir_file.txt) do (
set /a N+=1
set v[!N!]=%%a
)

If you want to remain both filename (only) and extension, you may use %~nxF:
如果您想同时保留文件名（仅）和扩展名，您可以使用%~nxF：
FOR /R C:\Directory %F in (*.*) do echo %~nxF

The answer by @AKX works on the command line, but not within a batch file. Within a batch file, you need an extra %, like this:
@AKX 的答案适用于命令行，但不适用于批处理文件。在批处理文件中，您需要一个额外的%，如下所示：
@echo off
for /R TutorialSteps %%F in (*.py) do echo %%~nF
