Refer to file made by date / time variable

#1 Post by drgt » 17 Oct 2021 09:10

Suppose
Dir /a-D /b >%date%%time%.txt

How to refer to that file further down the code?
Time would have advanced so %date%%time%.txt won't be found.

You know, there is a "Search this forum..." field directly on top of the list view of threads ...

Obviously you're asking questions before you even tried out anything. Not only that %time% advances, it also contains colons which are not allowed in file names. Use WMIC. The FOR /F loop in this thread creates a %LocalDateTime% variable that you can cut off after 14 characters in order to contain yyyyMMddHHmmSS. This order has also the adwantage of getting properly sorted in an explorer list view. And obviously a defined variable containing the date-time string can be re-used subsequently in the code, because its value doesn't change anymore.

Thank you Steffen.
I would have never found it...
Regarding the colons you mentioned, that is why I wrote "suppose'.

Do you actually believe that I recall thousands of threads and posts? Guess how I find the topics I link in your threads :wink:

E.g. if you want to get a timestamp as name for your file:
timestamp.png
timestamp.png (74.62 KiB) Viewed 2402 times
(yellow emphasizing is mine)
And once you know that WMIC is worth doing further investigation, just do it.
