如何制作一个批处理脚本，以递归方式在c中找到文件.bat？

Question

Im new to batch scripting and im trying to learn how I can make a script that can go recursively through the folders and if its founded give me the path, if not echo a simple message. i was starting by here:

@echo off
for /f %%f in ('dir bucle.bat /s/b') do @echo %f  %~tf
pause
exit 

but Im kinda stuck.

Answer 1

You are using a for command to process the output of a dir command. Just to found the file, you don't need all this. Simplify

dir c:\bucle.bat /s /b 

This searchs the file, when found shows it with full path and if not found echoes a error message.

Answer 2

try:

@echo off
for /f %%f in ('dir bucle.bat /s/b') do @echo %%f  %%~tf
pause
exit 

to echo only the path:

@echo off
for /f %%f in ('dir bucle.bat /s/b') do @echo %%f
pause
exit 

you can also use where command: http://ss64.com/nt/where.htm
and the exit command at the end isn't necessary...
PS: all your code is the same as this: dir bucle.bat /s /b

Answer 3

↑ denotes missing elements in the original code:

@echo off
for /f "delims=" %%f in ('dir bucle.bat /s/b') do @echo %%f  %%~tf
rem    ↑↑↑↑↑↑↑↑↑                                        ↑↑   ↑↑
pause

• "delims=" - to properly treat paths with spaces,
• %%f - loop variable.

You could specify starting directory for recursive searching:

for /f "delims=" %%f in ('dir C:\myfolder\bucle.bat /s/b') do @echo %%f  %%~tf

or even

for /f "delims=" %%f in ('dir C:\bucle.bat /s/b') do @echo %%f  %%~tf
