script to create a file with unique name

I'd like to know if there is a way to create a new file within a script that
have an unique name that contain the current date; i.e.: 10062005.txt.
Thanks in advance.

Hi,

With a VBScript:

'--------------------8<----------------------
dDate = Now

' using the ISO 8601 date format yyyymmdd so it is unambiguous and
' easily sortable in Explorer
sDate = Year(dDate) & Right(100 + Month(dDate), 2) _
& Right(100 + Day(dDate), 2)

sFileName = sDate & ".txt"

WScript.Echo "File name: " & sFileName

'--------------------8<----------------------



Or if you are using a batch file, you could use the code below.

It is using the ISO 8601 date format yyyymmdd so it is unambiguous
and easily sortable in Explorer.

--------------------8<----------------------
@echo off
setlocal
echo D = Now : WScript.Echo Year(D) ^& _ >%tmp%\today.vbs
echo Right(100+Month(D),2) ^& Right(100+Day(D),2) >>%tmp%\today.vbs

for /f "tokens=1" %%a in (
'cscript.exe //Nologo %tmp%\today.vbs') do set today=%%a

del %tmp%\today.vbs
echo File name: %today%.txt
pause
endlocal
--------------------8<----------------------


You can do it with "pure" batch file as well, using e.g the batch date
time functions from Ritchie Lawrence batch library available at
http://www.commandline.co.uk/lib

 

Here is a batch file solution:

@echo off
set d=%date:~4,10%
:again
set FileName=%d:/=%-%random%
if exist %FileName% goto again

%random% lies in the range of 1 .. 32,767.

 

Great!!
It works fine!
Thanks you.
