Is there a tool for Ubuntu to schedule jobs similar to at but for anacron instead if plain cron? Eg.

echo "rm -Rf /tmp/workdata.$$.*" | at now + 99 minutes

It doesn't have to be via anacron, just whatever my scripts can rely on to run either at the scheduled time or when the server is back online.

If it's a scheduler only root can use I'll just wrap the calls with sudo

Two game-changing things I've learned since then, that sort of resolve the matter:

  • at daemon already runs jobs that fell behind schedule eg. due to server outage
  • Using this property, anacron already sits on top of the crontab facility, and as bundled by default cannot schedule tasks at the hour/minute granularity, only month/day in its global config file in /etc (root owned).
