How to find a file without specifying folder/drive in bat or moon?

Question

How to find a file and save it in a variable?

I will use it for reading (this part is already solved), however, I want to locate without specifying folder/drive, for example .\Arquivo.txt.

I’ve tried that, only it doesn’t work when you’re reading...

I need this, since, if I would type the complete directory, it would work on my computer, however, in another would not be successful, since the folder/path/directories name, would not be the same.

How to do this in bat or moon?

• Update v2 Passing by parameter (lua.log) and insertion/input (lua.txt)...

Since I understand your comments, then you will call bat passing these arguments:

[Arquivo.bat] [lua compilador(a variável do arquivo lua q também vou ter q achar)] [arq(a variável do arquivo txt)]

---

• Therefore to the bat passing by arguments without passing the MD5:

---

 %0 = [Arquivo.bat]          
 %1 = [lua compilador(a variável do arquivo lua q também vou ter q achar)]
 %2 = [arq(a variável do arquivo txt)]
---------------------------------------------------------------------------
    %0          %1           %2   
Q395923.cmd "buscar_arq" "algum_txt"

---

• The code in bat without hash/MD5, would be:

---

@echo off && setlocal enabledelayedexpansion & title < nul && title Q395923 & echo/ 

set "_file=%~1" && set "_txt=%~2" & echo/ Procurando pelo arquivo: !_file!... & echo/

for /f %%f in ('%windir%\system32\mountvol^|find /i ":\"')do for /f %%F in ('cd /d "%%f" ^& cd\ ^& %windir%\system32\where /r .\ "!_file!" 2^>nul')do (
   set "_lua=%%F" && set "_pasta=%%~dpF" && goto :^)
          )

:^)
if "!_lua!/." == "/." (echo/ Arquivo "%~1" n localizado^!! & goto :eof) else (echo/  Arquivo: !_file! &echo/    Pasta: !_pasta!) 

rem:: variável !_lua! vai armazenar o caminho completo buscado no bat = %1 no bat
rem:: variável !_txt! vai armazenar o arquivo.txt, passado no comando = %2 no bat

---

• Therefore to the bat passing by arguments with the MD5:

---

 %0 = [Arquivo.bat]          
 %1 = [lua compilador(a variável do arquivo lua q também vou ter q achar)]
 %2 = [arq(a variável do arquivo txt)]
 %3 = [Hash(MD5 do arquivo que busca encontrar)]

Obs.: A computer search (all driver/folders/subfolders) will take...

---

To search for a file (archiv_target.ext), I suggest first getting the MD5 of the target file, to check whether the MD5 of the file found by bat be the even that searches, avoiding finding any file with the same name but its content differs from the desired file.

---

To obtain the MD5 with the certutil.exe use the code below, which will display on the screen the string of MD5 and will also move a copy to your Crtl+C, making it easy to paste into your file bat:

@for /f delims^=^ ^tokens^=* %%i in ('%windir%\system32\certutil -hashfile "c:\pasta\subpast\arquivo_alvo.ext" md5^|find /v ":"')do (
    @echo/%%i & echo/%%i|clip
    )

Obs.: Certiutil.exe already comes with Windows XP, 7, 8, 8.1, 10 and server versions.

To locate the file and not knowing what drive or folder this file might be in....

1) Use of command mountvol to list all drivers available in the system

2) Passing the exit from mountvol within a looping for, we can get the desired file with the command **where* in each drive and its sub-folders

3) Being found by the command where, we will pass the exit of this command to the with certutil and thus get the MD5 from the archive

4) Using a if, we can check if the found file has the sum MD5 same as the file buscado/desejado.

@echo off && setlocal enabledelayedexpansion & title < nul && title Q395923
set "_file=arquivo_alvo.ext" && set "_hash=d3369d9f356dc5795a49ae2ecca5787a"

for /f %%f in ('mountvol^|find /i ":\"')do for /f %%F in ('cd /d %%f ^& cd\ ^& where /r .\ "!_file!"')do >nul set "_lua=%%F" && (
     for /f delims^=^ ^tokens^=* %%i in ('%windir%\system32\certutil -hashfile "%%~F" md5^|find /v ":"')do if "%%~i" == "!_hash!" (
         set "_path_file=%%~dpF" & goto :^))
         )
echo/ Arquivo "!_file!" n localizado^!! & goto :eof 

:^)
echo/ Arquivo: "!_file!" &echo/   Pasta: "!_path_file!" & echo/    Hash: "!_hash!"

• Without checking if the MD5 matches the filing cabinet you seek:

To locate a file without knowing the folder and being on the same drive:

---

cd\ & where /r "." "arquivo.ext"

Inside a bat using for:

---

@echo off & cd\ 

for /f %%f in (`where /r "." "arquivo.ext"`)do set "_path_file=%%~dpf"
echo/%_path_file%
