This is My Test Batch File:
This is a Batch That Make Another Batch


>Main.bat (
   echo.@ECHO OFF
   echo.CLS
   echo.TITLE Test Batch
   echo.START /max %ComSpec% /c "%Temp%\md5.exe"
   echo.Ping localhost -n 1 -w 1 >nul
   echo.EXIT
)
>>NewFile.bat
type NewFile.bat

The firt Problem is:
the %ComSpec% always appear in the NewFile.bat As "C:\Windows\system32\cmd.exe" and the %temp% Appear as "C:\Users\Admin\AppData\Local\Temp"
is there away that make them appear as i wrote in the Main.bat

The second:
The Ping line when i end it with >nul the line dosn't appear and when i remove >nul it appear
and i want the entire line to be written in the file as in the code up there ... any one knows

thanks in advance

To sucessfully make batch files from batch files, you need to employ the escape character ^

instead of

Code: Select all

echo.START /max %ComSpec% /c "%Temp%\md5.exe"

use

Code: Select all

echo.START /max ^%%ComSpec^%% /c ^"^%%Temp^%%\md5.exe^"

(percent signs like to be odd in batch)

EDIT:
just saw part about ping :
again use

Code: Select all

echo.Ping localhost -n 1 -w 1 ^>nul

I also removed the return carriage after the block b/c that changed the file being written to . . .
end code should look like:

Code: Select all

>Main.bat (
   echo.@ECHO OFF
   echo.CLS
   echo.TITLE Test Batch
   echo.START /max ^%%ComSpec^%% /c ^"^%%Temp^%%\md5.exe^"
   echo.Ping localhost -n 1 -w 1 >nul
   echo.EXIT
)>>NewFile.bat
type NewFile.bat

Captcha142 has almost told you the right story.

There is no need to escape % or " below, just double the % to %% and it will work.

echo.START /max %%ComSpec%% /c "%%Temp%%\md5.exe"
