Keep a "latest" symlink for timestamped cron logs (programming.dev)

Use ln -sf to update a symlink after each cron run:

0 */8 * * * TIMESTAMP=$(date +\%Y-\%m-\%dT\%H;\%M;\%S) && LOG="$HOME/logs/${TIMESTAMP}_job.log" && /path/to/script.sh >> "$LOG" 2>&1 && ln -sf "$LOG" "$HOME/logs/latest_job.log"

Any active communities where I can learn more cool things like this?

Or use systems timers which keep track on this information for you. Can even tell you when the job will next run and automatically captures the logs and exit status from the runs.

Or use systems timers

systemd timers? Isn't that dependent on whether or not there is systemd? I thought there were Linux distros that don't use it.
