Hi, I need to create a batch that creates a txt file, here is the fun part the batch will run every 1 to 5 minutes (the time is not impotant)  and a new file will be created with a new name, this name has to be in sequence to the last one created or we can have the time it was created (HH:MM:SS)

thanks

    you did not mention the language, so i suppose you need win* batch :-)
    the problem is how to create next file name in the sequence, where
    win* batch language lacks basic arithmetics and string functions.

    so, here is a batch file to create a new file name in the sequence.
    the file name will be <directory>\<prefix><number>.<extension>
    the output is put in the NEWNAME shell variable, so you can use it
    in another batch. It will generate sequences of up to 10000 file names,
    but it can be easily extended.

    this batch will run on (almost) every version of win* (and DOS).
    It can be simplified a bit if you're using only XP...
    With WinXP, it can be extended to add current date to the file name
    or create a directory with current date as the name,
    and so to create up to 10000 file name daily. Ask if you need that.

    ----8<---- newname.bat ----8<----
    @echo off

    rem ---- configuration ----
    set DDIR=c:\destination\directory
    set PREFIX=f_
    set EXT=txt
    rem --- end of config ----

    set A=0
    set B=0
    set C=0
    set D=0
    :try
    set NEWNAME=%DDIR%\%PREFIX%%D%%C%%B%%A%.%EXT%
    if not exist %NEWNAME% goto end
    if %A%==9 goto 20
    set V=A
    set X=%A%
    goto inc

    Hi guys,

    Not shooting for points here but I came up against a similar issue with trying to date stamp a file and found this script which is quite cool. It puts all the different date/time parts into environment variables which can then be referenced using %DD%/%MM%/%YY% %HH%:%MIN%:%SS% or any other combo of these variables.

    REM ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    For /f "tokens=1-7 delims=:/-, " %%i in ('echo exit^|cmd /q /k"prompt $D $T"') do (
          For /f "tokens=2-4 delims=/-,() skip=1" %%a in ('echo.^|date') do (
                set dow=%%i
                set %%a=%%j
                set %%b=%%k
                set %%c=%%l
                set hh=%%m
                set min=%%n
                set ss=%%o
          )
    )
    if %HH%==10 goto end
    if %HH%==11 goto end
    if %HH%==12 goto end
    set HH=0%HH%

    :end
    REM ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
