Remove blank lines at the end of a text file

I have a txt file that gets uploaded to us on a nightly basis.  This file is processed by one of our systems.  On occasion this file has 2 or 3 blank lines at the very end.  This causes issues when being processed.  Need a way to remove these blank lines after it is uploaded before it gets processed.   I'd prefer some sort of dos batch file or script.  All lines have data except for the few at the end.

Thanks!

Try if that works for you:
@echo off
setlocal
set InFile=C:\Temp\test.txt
set OutFile=C:\Temp\test2.txt
(for /f "delims=" %%a in ('type "%InFile%"') do echo %%a)>"%OutFile%"

You can remove all blank lines using just

Find /v "" < file.txt > file2.txt

And then process file2.txt or rename as needed.

On phone so will pass more if needed when on PC.

The Find /v "" < file.txt > file2.txt doesn't work for me; file2 still has the empty lines.
What works is findstr.exe and a regular expression:
findstr.exe /r "." < test.txt > test2.txt

I think you guys already knew this :).  See Q_26947689.

Looks like a reasonable short version is

findstr . file1.txt >file2.txt

I suppose the other logical way is to select the lines that are wanted too, i.e. selecting all lines with comma or 0 or some other character that MUST be in each line for it to be imported anyway.
