Why and How to check list if file exist or not in Windows?

Why ?

I have a system will generate a list of files in daily bases and I need to make sure that these file got generated by running a CMD script to check if file exist on that folder or not , this purpose can be achieved using different way however my monitoring was only possible to be using CMS, thus, I have wrote the below code to achieve this goal .

How ?

Below is a Windows CMD code that will check 19 files with pattern file{date} and date format is differ in some files, If you run the code against these file you will be reported if it is exist or not and you may custom the code to achieve different goal as well ,:

1- Code below:

@echo off

for /f "tokens=2 delims==" %%G in ('wmic os get localdatetime /value') do set datetime=%%G

 

set year=%datetime:~0,4%

set month=%datetime:~4,2%

set day=%datetime:~6,2%

 

echo checking files for today %year%/%month%/%day%%time%

 

 

::MonthName.cmd::::::::::::::::::::::::::::::::::::::::::::::::::::::

setlocal EnableDelayedExpansion

for /F "tokens=1-4 delims=.-/ " %%A in ("%DATE%") do set month=%%B

set monstring=JANFEBMARAPRMAYJUNJULAUGSEPOCTNOVDEC

set /a mm=(100%month%%%100)*3-3

:: Use a call to get %mm% evaluated first.

call set mmm=%%monstring:~%mm%,3%%

::echo Monthname=%mmm%

::MonthName.cmd::::::::::::::::::::::::::::::::::::::::::::::::::::::

 

set elem[0]=file1_%year%%month%%day%.txt

set elem[1]=file2_%day%%mmm%%year%

set elem[2]=file3%day%%mmm%%year%

set elem[3]=file4%day%%mmm%%year%

set elem[4]=file5_%day%%mmm%%year%

set elem[5]=file6%year%%month%%day%.txt

set elem[6]=file7%year%%month%%day%.txt

set elem[7]=file8_%year%%month%%day%.txt

set elem[8]=file9_%year%%month%%day%.txt

set elem[9]=file10_%day%%mmm%%year%

set elem[10]=file11%day%%mmm%%year%

set elem[11]=file12%day%%mmm%%year%

set elem[12]=%day%%mmm%%year%

set elem[13]=file13%day%%mmm%%year%.txt

set elem[14]=file14%day%%mmm%%year%.txt

set elem[15]=file15_%year%%month%%day%.txt

set elem[16]=file16_%year%%month%%day%.txt

set elem[17]=file17_%year%%month%%day%.txt

set elem[18]=file18_%day%%mmm%%year%

 

cd C:{path_to_files}\files_generation_checkup\files

::@echo on

for /L %%a in (0,1,18) do (

if exist !elem[%%a]! (call echo FILE %%elem[%%a]%% IS EXISTS) ELSE (call echo FILE %%elem[%%a]%% DOES NOT EXIST)

)

::if not exist !elem[%%a]! (call echo FILE %%elem[%%a]%% DOES NOT EXIST)

::echo !elem[%%a]!
