In UNIX there's a command called 'crontab'. You use it to schedule programs to run automatically at whatever interval you tell them to. There's a few options you can give to control its behavior. For example, 'crontab -e' will bring up an editor so you can modify the current crontab file. Did you also know 'crontab -r' will remove the crontab file for the current user with no questions asked? If you want to be prompted before removing a crontab file you have to say 'crontab -ri'. Now, I don't know about you but if I took the time to type the 'i' to begin with I'm naturally going follow that up with a 'Y' response. This is the opposite behavior of the 'rm' command which will prompt you unless you specifically use '-f' to suppress the "Are you sure?" prompt. But what really gets me about the 'crontab' command is that 'e' (edit) and 'r' (remove) are right next to each other on the keyboard!
