There is one way, although there are some dependencies
attached to the at or
- This information was found in the Solaris (Unix) man
pages. There may be Linux equivalents.
- There are conditions attached to the existence and contents
two files, /usr/lib/cron/at.allow and /usr/lib/cron/at.deny.
Users are permitted to use at and batch (see below) if their
name appears in the file /usr/lib/cron/at.allow. If that
file does not exist, the file /usr/lib/cron/at.deny is
checked to determine if the user should be denied access to
at. If neither file exists, only a user with the
solaris.jobs.user authorization is allowed to submit a job.
If only at.deny exists and is empty, global usage is permit-
ted. The at.allow and at.deny files consist of one user name
One example they give is:
Example 3: Self-rescheduling a job
Of course, you could talk to the sys admin and request the
priviledge of using crontab, at or batch.

Net::Daemon or Chapter 17, recipe 17.15 in The Perl Cookbook. If you're on a Win32 box, I think there's a Win32::Daemon as well.
You would have the program sit there and wait for a certain time or time interval, then do it's thing. A quick Super Search on 'daemon' or 'cron' will give you lots of other options.
Apply yourself to new problems without preparation, develop confidence in your ability to to meet situations as they arrise.
Some time ago, I pointed out an emulation of cron running in Perl. If you can run perl-programs under your account (which I assume you can), you might give this a go. You can find it under www.megadodo.demon.co.uk/perl/. The comments in the code say it's for NT, but I assume it shouldn't be difficult - if anything has to be changed at all - to get it to run on linux.
Hope that helps,
but as far as i understand this thing from megadodo it will run as a service under nt... how could i emulate such on a linux box?
