How do I make a batch log file? - batch-file

Question

How do I make a log file from this code. This has been answered a ton, but this file is huge and I want a simple log file. As you see I also tried to add a log file names RandomNamesLog.log. See if the output goes there.
I want all the code to be outputted into the log file, with error messages and confirm messages, like removing the #ECHO OFF value.
If you need more on what I want, please tell me.
#ECHO OFF
SETLOCAL EnableDelayedExpansion for /F "tokens=1,2 delims=#" %%a in
('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do ( set
"DEL=%%a" )

I have rewritten your script fixing all of the problems I could see and removing the pointless code to add colored text.
Test it to see if it works as it should adding whatever you think I've missed.

Once you are happy with it edit your opening question explaining what it is you want to have in the log file and how you need it to look.

Answer 2

I use this. it seems to work.
It just starts a log file and maintains logs.
You can set logpath and logname (base name) then you call this create_logfile
It creates a semi-random log file.
Now you write to the set logfile
I'm not an advanced coder. Please feel free to correct:
#echo off
rem
echo %date% %TIME%
rem Log File Path
if "%logpath%" == "" set logpath=%~dp0
if "%logpath:~-1%" == "\" set logpath=%logpath:~0,-1%
rem Make log file name
if "%logname%" == "" set logname=log
set t=%TIME: =0%
set d=%DATE%
set logfilename=%logname%_%d:~12,2%%d:~4,2%%d:~7,2%%t:~0,2%%t:~3,2%%t:~6,2%.log
set t=
set d=
rem Test
echo full log file name = %logfilename%
echo find base log name = %logfilename:~0,-17%
echo log path = %logpath%
rem Logs to maintain
set /a dellog=5
rem Find file to delete
set var=

for %%a in (%logpath%\%logname%*.log) do (

)
rem Delete old log
echo file to delete %fltodel%
if exist %fltodel% (del /q %fltodel%) else (echo "%fltodel%" does not exist. nothing to delete.)
echo tryed to delete
rem Create Log File and logfile attribute
set logfile=%logpath%\%logfilename%
if exist %logfile% (
echo start logging... "%~0" on %date% %time% >> %logfile%
) ELSE (
echo Start Log for "%~0" on %date% %time% > %logfile%
)
