You're overlooking at's ability to be used as a one-time scheduler. Cron
is really intended to be used for regular tasks. at is the sort of thing
you can use to do things once, for example, "I am going to be on vacation
on the 23rd, so I'll use at to mail the report that people are accustomed
to seeing from me that day" or "Maintenance is shutting down the building
tonight, I need to remember to power down all the machines at 9:00."
Cron isn't really suited to this sort of thing. Yes, you can use cron for
it, but why? Just use at.
