Cannot find crontab entry for a scheduled shell script

Question

My predecessor set up a basic installation of CrunchBang in a VirtualBox VM - The Windows host runs a scheduled task to boot the VM, then CrunchBang runs a shell script some 10-15 minutes later to rsync some files to a local drive. Windows is booting the VM just fine, and CrunchBang's script appears to be functioning correctly and running according to its schedule. But I would like to tweak CrunchBang's schedule a bit, and I can't figure out how/where the script is being scheduled. crontab -l returns no crontab for xxx for both the default user and root, and crontab -e likewise results in empty files.

Is there another location where the schedule entry could be saved? An alternative to cron that may be running it instead?

Thanks.

Answer 1

If it's starting a consistent 15 minutes after boot, it might be a startup script that has a built-in delay/sleep before running. You might also look at /etc/rc.local, or in /etc/init.d, in case it's not cron.

Answer 2

Check under /etc/cron.d/ for scripts.
