Batch script problem:splitting a big txt file into many 4000 lines
script:

Code: [Select]

@echo off
    setlocal enableextensions disabledelayedexpansion

    set "nLines=4000"
    set "line=0"
    for /f %%a in ('type file.txt^|find /c /v ""') do set "fileLines=%%a"

    < "file.txt" (for /l %%a in (1 1 %fileLines%) do (
        set /p "data="
        set /a "file=1+line/%nLines%", "line+=1"
        setlocal enabledelayedexpansion
        >>"pass!file!.txt" echo(!data!
        endlocal
    ))

    endlocal
Line 4001 is not empty,looks strange,here snapshot:

What is generating the Text File? And curious why not just FTP the file from remote system to yourself vs splitting it into 4000 line chunks?

You do not need the lines variable.  You could just write that line like this.

Code: [Select]

set /a "file=1+(%%a-1)/nLines"Not sure what your NULL issue is.  As far as I know, batch cannot generate a null character on its own.

Were both on same page with that one. That's why I also asked what is generating this text file.  ;D
