Hi Friends,
Please can any one help to create scrip to delete all files on define date.
for example I would like to delete all files of directory "C:\test\" on date 24/10/2014.
appreciate in advance.

You will need to create a Windows scheduled task and have it run this command in a batch file.

Thanks for your reply.
My system is DOS operating system. I would make it in Autoexec.bat

Which version of dos are you using?
Is it FreeDos or Microsoft MSDOS V6.22 or some other dos system?

Then a Qbasic script with batch file is useful:
Code: Select all
@echo off
echo open "!_~_!.bat" for output as #1: a$=DATE$>!_~_!.bas
echo ? #1, "SET DAY="+RIGHT$(a$,4)+LEFT$(a$,2)+MID$(a$,4,2)>>!_~_!.bas
echo SYSTEM>>!_~_!.bas
qbasic /run !_~_!.bas
call !_~_!.bat
del !_~_!.bat
del !_~_!.bas
if %day%==20141024 deltree /y c:\test\

I never realized just how I easy I had it with modern batch until I tried to help with this (I did eventually get it, though).
Try this:
Code: Select all
@echo off
REM Based on www.robvanderwoude.com/datetime.php
ver | date > temp.bat
echo set date=%%4>current.bat
call temp.bat
del temp.bat
del current.bat
echo y > y.txt
if "%date%"=="24-10-2014" del C:\test\*.* < y.txt
del y.txt
Note that this code assumes the output of the DATE command is in the DD-MM-YYYY format.

del y.txt
This also works in MSDOS
The date variation was an issue back then too, and which is why the qbasic solution was preferable as it eliminates region differences.

It took me way longer than it should have to figure out a workaround for that not working in a batch script. Piping clearly works in the script, but does piping the output of an echo behave differently in DOS scripts vs on the command line?

Do you have an example where it failed?
I don't recall a command.com prompt being any different in that respect.

echo y|del c:\test\*.* didn't work (nothing was echoed to the screen and no files were deleted) when I tried putting it in the script, but it works fine on the command line.

It works fine in my MSDOS 6.22 VM in a batch file and also on the dos prompt.
The screen output is the same too.
Which OS are you using to test it in?

I'm also running an MS-DOS 6.22 VM.

Add an echo to show you the IF date compare - and you are using c:\temp and not c:\test

It definitely
should be working, and if it's working for you and not me, then there's some issue on my side. Maybe I have some syntax error where the del thinks the entire if statement is being piped into it?
