Windows批处理文件，通过子文件夹循环

Question

I didnt succeed writing an approriate batch file and would appreciate some help.

Let's say I have an exe in D:\\Test\\ called script.exe. To execute this script.exe it requires an additional argument of a .bin files (eg bin01.bin, bin02.bin).

Therefore it would be like: script.exe -i bin01.bin, script.exe -i bin01

I want the script to execute with all .bin files from all subfolders

D:\\Test\\script.exe
D:\\Test\\Folder01\\bin01.bin
D:\\Test\\Folder01\\bin02.bin
D:\\Test\\Folder02\\bin01.bin
D:\\Test\\Folder03\\bin01.bin

anyone could help me here? Thanks a lot in advance.

For direct execution from within a command prompt window:

for /R "D:\Test" %I in (*.bin) do @D:\Test\script.exe -i "%I"

And the same command line for usage in a batch file:

@for /R "D:\Test" %%I in (*.bin) do @D:\Test\script.exe -i "%%I"

The command FOR searches recursive in directory D:\\Test and all subdirectories for files matching the wildcard pattern *.bin .

The name of each found file is assigned with full path to case-sensitive loop variable I .

FOR executes for each file the executable D:\\Test\\script.exe with first argument -i and second argument being the name of found file with full path enclosed in double quotes to work for any *.bin file name even those containing a space or one of these characters: &()[]{}^=;!'+,`~ .

@ at beginning of entire FOR command line just tells Windows command interpreter cmd.exe not to echo the command line after preprocessing before execution to console window as by default.

@ at beginning of D:\\Test\\script.exe avoids the output of this command to console executed on each iteration of the loop.

Most often the echo of a command line before execution is turned off at beginning of the batch file with @echo off as it can be seen below.

@echo off
for /R "D:\Test" %%I in (*.bin) do D:\Test\script.exe -i "%%I"

For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.

• echo /?
• for /?
