Shell Programming and Scripting

Hi guys just wondering how i could make one of my scripts run unattended without the use of cron?

you can use at command.. go through at man page

The only issue is that we cant do it that way because the Administrators disable cron and at access.

There are probably reasons they disabled cron, so workarounds are somewhat likely to be shut down for the same reasons. But anyway, you could run a background script which just stays dormant and wakes up at predetermined times to start up child processes, i.e. your own little cron daemon. Or if you have ssh login access, run a script on another machine's crontab which logs in over the network and runs the commands you want.
