Hey all... Before trying to reinvent wheels, does anyone have a script
to do more or less the following:

logic:
if [ today = 05/21/2007 ]
then
run this script (using at) incremented 30 days from now
fi

I don't need it to run on the 30th day of the month (s'what cron is
for) just once in 30 days from the current date. (Thanks in advance
before I forget)...

% at now + 30 days
at> echo And 30 days on
at> <EOT>
job 1182341860.a at Wed Jun 20 14:17:40 2007

Also possible things as "time + 30 days" (note that this will give you 30
days from the next occurence of time and if you schedule a job at
noon every 30 days, you'd probably need to reschedule using
"at noon + 29 days" though it appears to give some slack.
(rounds down to whole minutes first)

A bit offtopic, but for people who need to manipulate dates from scripts,
I've written a bunch of std C and sh utilities a long time ago and use them
regularly: http://www.gdargaud.net/Hack/SourceCode.html#StrfTime
In particular it can compute dates in the future.

you might try "at -f script now + 43200 minutes" 43200 minutes is
equal to 30 days.

Any of the following will work :
'at now + 2 fortnights + 2 days <furlong'
'at now + 4 weeks + 2 days <furlong'
'at now + 30 days <furlong'
'at now + 7200 hrs <furlong'
