How I read a file .txt and put the last line in a variable

[julianfiglioli]

People, I am from Brazil. My English is not very well! Sorry.

I need read a file .txt, where, I need put the last line in a variable.

I am tryng find de number of lines and with a FOR /F read line and line.

But not this going right.

@echo off
setlocal enableextensions enabledelayedexpansion

set/p n=<teste.txt

REM ### Here I cat the number of the lines ###
type teste.txt | find /v /c "" <teste.txt >nlinhas
set/p l=<nlinhas

REM ### Variable that sum ###
set num=0

REM ### Read line and line ###
FOR /F %%n in (teste.txt) do (

if %num%==%l% (
echo %%n
goto :fim
)
set/a num=num+1 <== Where I put this code, occurs syntax error
)

endlocal

This should be enough:

@ECHO OFF
for /f "tokens=*" %%a in (teste.txt) do SET LINE=%%a
echo %LINE%

Every new read line will set the variable LINE. When all lines are read, you'll end up with the last line as the value.
