croncrontablinux

I need to run a script when i login for first time in a day. I may reboot or shutdown and then power on during the day. But i do not want the job to run during those power ups. It should run only once per day.

Best Answer

use anacron:

Anacron can be used to execute commands periodically, with a frequency specified in days. Unlike cron(8), it does not assume that the machine is running continuously. Hence, it can be used on machines that aren't running 24 hours a day, to control daily, weekly, and monthly jobs that are usually controlled by cron.
