ISO 8601 is amazing for data storage and standardizing the date.

Display purposes sure, whatever you feel like

But goddammit if you don’t use ISO 8601 to store dates, I will find you, and I will standardize your code.

epoch not acceptable then?

[-] Rootiest@lemm.ee 11 points 1 year ago

Epoch is also acceptable if humans don't need to understand it

[-] cerberus@lemmy.world 2 points 1 year ago

I will agree it’s a valid storage but it has to be specified in ms

I actually need to standardize my code. I've got "learning F2" as something I want to do soon. The goal: use the exif data of my pictures to create [date in ISO 8601] - [original filename].[original file type termination]

So a picture taken the third of march 2022 titled "asdf.jpg" would become "2022-3-3 - asdf.jpg"

Help? lol

If you're on Linux exiftool can get the creation date for you: exiftool -p '$CreateDate' -d '%Y-%m-%d' FILENAME, and you could run tgat in a loop over your files, something like:

mkdir -p out
for f in *.jpg
do
createdate=$(exiftool -p '$CreateDate' -d '%Y-%m-%d' "${f}")
cp -p "${f}" "out/${createdate} - ${f}"
done

Obviously don't justbgo running code some stranger just posted on the internet, especially as I haven't tested it, but that should copy images from the current directory to a subdirectory called 'out' with the correct filenames.

I did this in the past and I would search through my notes... If I had notes ffs.

Can you give more context, what are you using? Language / system / etc?

[-] snek_boi@lemmy.ml 1 points 1 year ago

I'm using NixOS. Ext4 filesystem. As to language, I'm not entirely sure what you mean. If you refer to the character set in the filenames, I think there are no characters that deviate from the English alphabet, numbers, dashes, and underscores.

[-] cerberus@lemmy.world 1 points 1 year ago

Oh ok so you’re more so working with folder structure etc, so bash for when you plug-in a card?

I’m thinking in more programmatic terms, there’s definitely some bash scripting you can execute. Or just go balls out and write a service that executes on systemctl
