[BATCH] Count number of lines in a text file

Solved

Hello everyone,

There are many topics, and I've (almost) found my happiness.
I still have a problem that I can't solve.

The line count is incorrect. I'm missing more than 30 lines.
Here's my code: 

@echo off set nb=0 set /p fichier="Drag your file here" for /f "tokens=*" %%i in ('type %fichier%') do ( set /a nb+=1 ) echo %nb% pause>nul


The file is a *.log file; I don't know if that changes anything compared to a *.txt
It has 191 lines when opened with Notepad and 201 when opened with Notepad++.

Configuration: Windows XP / Safari 536.11

    I think I have the solution: 

     @echo off setlocal enabledelayedexpansion set nb=0 set /p fichier="Drag your file here" for /f "delims=" %%a in (%fichier%) do ( set /a nb=!nb!+1 ) echo %nb% pause>nul endlocal

      this loop ignores empty lines in the file 
      for /f "delims=" %%a in (%fichier%) do (
      1

    hello,

    if I want to count the number of lines in several TXT files, how would I do that please?

    I did it like this but it doesn't work

    @Echo OFF

    for /f "delims=;" %%a in (fichier.txt) do (

    for /f "delims=" %%i in ('type %%a.txt') do ( set Compt=0 set /a Compt+=1
    echo %Compt% >>resultats.txt
    )
    )

    pause
    1

    Indeed, I have the right number of lines (the one from np++) thank you :)
    How can I store this number in a variable?

    The end goal is to retrieve the first 3 and the last 3 lines of the file to put them in a log file.

    this loop ignores empty lines in the file 
    for /f "tokens=*" %%i in ('type %file%') do
    pass through a loop to store the result in a variable
    C:> type f1.txt aa bb cc dd C:> find /v /c "" <f1.txt c:=""> for /f %a in ('find /c /v "" ^< f1.txt') do @set l=%a C:> echo %l% 7 C:</f1.txt>

    Perfect !!
    (just needed to use %%a instead of %a)

    Thank you very much!

    Just need to get my lines and it's all good.
