Rename file with current date/time

[Emo]

I hope this is simple :)

I'm looking to rename a file in C:\folder\dailybackup.bak to C:\folder
\MMddyy-hhmm.bak

I just need to do it for one file. The original filename with always
be "dailybackup.bak"

I understand how to use get-date and how to format it as in:

$datetime = get-date -f MMddyy-hhmmtt (using tt for am or pm)

And I understand how to do a simple file rename using ren. In rename,
it asks for the path and then NewName...but I can't figure out how to
get the info from $datetime into the filename.

so...how can I rename the file using the info from $datetime?

I'm pretty new to powershell so any help is greatly appreciated :)

IIUC, you need this:

rename-item c:\folder\dailybackup.bak -newname ($datetime + ".bak")

Thank you so much! I just couldn't get the syntax. I kept trying -
newname %$datetime%.....etc....with various quotes...etc LOL

Thanks again

Hi all, I see there was a bit of an argument above. I couldn't get either of the suggestions to work for a file, maybe they have changed the powershell commands since. The above suggestion left me with a .AxA file so I've tweaked it for anyone else googling the answer. The following works well from CMD (so can be made into a batch script):

Powershell Rename-Item C:\filename.txt "filename_$((get-date).toString('dd-MM-yyyy')).txt"

This will give you C:\filename_05-05-2020.txt if it was ran today.

Best of luck!

Uhmm, yes, this question was posted over 4 years ago.
Did you mean to ask a question about this question or did you mean to
provide a new answer in additon to the solution that was provided back
then or why did you respond to this posting with a full-quote but no
comment of your own?

the above command is not working

[Jürgen Exner]

Oh, it took you only 6 years to check the command?

the above command is not working

"is not working" is a very useless problem description.

This command is working perfectly fine with me.
It assigns the current date/time to $datetime.

What did you expect it to do?
And what did you observe it doing instead?
Just saying "is not working" without providing those 2 critical details
is pointless.
