Replacing a string in all config files across machines with a script

Question

I have the below task and I am wondering what would be the best and quick way to do this. I am thinking scripting rather than a C# app but struggling with scripting in DOS. I wanted to use powershell but not sure if all the machines have powershell installed :

I have around 15 windows machines and in each machine, I want to find all *.config files (in say C:\ and D:) and replace a specific word (db name).

I can execute this locally or execute this remotely, since I have login access to the machines. But the tough part is the script.

Any pointers would be great to start.

Thanks.

This is untested and destructive so test it first.- it is designed to search C: and D: drives and all subdirectories and modifies all *.config files.

It is set to look in c:\abc and d:\abc trees atm so put some files and folders in there and test it.

@echo off
for /f "delims=" %%a in ('dir c:\abc\*.config d:\abc\*.config /b /s /a-d') do (
call :sar "%%a" "%%a.tmp" "db_name" "new_db_name"
move /y "%%a.tmp" "%%a" >nul
)
goto :EOF
:sar
:: inputfile outputfile regexp_search replacement
if "%~5"=="" (set global=true) else (set global=false)
set s=regex.replace(wscript.stdin.readall,"%~4")
 >_.vbs echo set regex=new regexp
>>_.vbs echo regex.global=%global%
>>_.vbs echo regEx.IgnoreCase=True
>>_.vbs echo regex.pattern="%~3"
>>_.vbs echo wscript.stdOut.write %s%
cscript /nologo _.vbs <"%~1" >"%~2"
del _.vbs
goto :EOF
