In the subject you wrote “successful full sys update” but the script and the other suggestions I see so far don’t actually handle the “successful” part.

The log message only tells you that the update was started and the db mtime only indicates that the db was touched without saying anything about success.

I’d go about this by always performing the updates through a wrapper script that could check the exit status of the pacman or yay command and record a timestamp accordingly.

The Internet was already a teenager by then. It hooked up with Hypertext and the result was this brat called WWW.

My first WWW experience was trying Mosaic on a computer without an Internet connection. I knew what the Internet was, we had access through an X.25 PAD (kind of like a dial-up shell session, no direct TCP/IP) so I’d already used IRC, Usenet, FTP, Archie, Gopher etc. I also knew what hypertext was from various local help and document browser programs. So I figured out that Mosaic can display HTML documents but of course without Internet connectivity just showing some local demo pages didn’t seem all that special. But I figured it out later on…
