Ta for this. I never really bothered with this before, but now that you've shown me how to do it... just checked the latest Debian 12 ISO that I downloaded and got the red highlight. 🙂

I finally found a video with a checksum command that actually worked for once. Unfortunately I now receive 'No such file or directory' when using it. Since dragging and placing the file after the sha256sum command no longer works so I'll have to take my chances that the iso file isn't corrupted. Terminal sucks.

Thanks. But kinda weird that they use red for a successful result. Red makes it feel like somethings wrong
