How to change multiple file names according to there names along with date

I have 7 files. in bat file I want to check name of files and then raname with current date. just like an if/else condition

Example

  1. abc.txt rename to xyz20190715_1.txt (xyzyyyymmdd_1.txt)
  2. pqr.txt rename to def20190715_1.txt (defyyyymmdd_1.txt)

I'm new to batch files and tried this:

 for /f "tokens=1-5 delims=/ " %%d in ("%date%") do rename
 "abc.txt" %%e-%%f-%%g.dat

Expected output

  1. abc.txt rename to xyz20190715_1.txt

  2. pqr.txt rename to def20190715_1.txt

@echo off

for /f "usebackq" %%B in (`"powershell (Get-Date).ToString('yyyyMMdd')"`) do set "datetime=%%B


echo Today's Date %datetime%
ren "contract.txt" "DNSM%datetime%_x.DAT"
ren "security.DAT"" "NSM%datetime%_x.DAT"
ren "Participant.txt" "PM%datetime%_x.DAT"
ren "SCRIP_master.txt" "BSM%datetime%_x.DAT"
ren "DPRxxxx" "BSE_YearlyHL%datetime%_x.DAT"
ren "fo_participant.txt" "DPM%datetime%_x.DAT"
ren "spd_ contract.txt" "SCM%datetime%_x.DAT"

"to loop through files" is something like 

for %%I in (*.txt) do echo %%I

that's why I asked how to know the substitutions.

As there seems to be no rule, you have to rename each file individually (no big harm with only 7 files, but with a hundred ore more it would drive you crazy). I also used a differnt way to get the date string (independent of locale settings):

@echo off
for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set "datetime=%%I"
set "datetime=%datetime:~0,8%"

ren "contract.txt" "DNSM%datetime%_x.DAT"
ren "security.DAT"" "NSM%datetime%_x.DAT"
ren "Participant.txt" "PM%datetime%_x.DAT"
ren "SCRIP_master.txt" "BSM%datetime%_x.DAT"
ren "DPRxxxx" "BSE_YearlyHL%datetime%_x.DAT"
ren "fo_participant.txt" "DPM%datetime%_x.DAT"
ren "spd_ contract.txt" "SCM%datetime%_x.DAT"

If the question is to get the actual date, then for today's date it's better to do the following:

for /f %%a in ('wmic path win32_LocalTime Get Day^,Month^,Year /value') do >nul set "%%a"
    set Month=00%Month%
    set Month=%Month:~-2%
    set Day=00%Day%
    set Day=%Day:~-2%
set today=%Year%%Month%%Day%

Otherwise you need to ask a real question, which starts with "how do I"
