Hi all,

Simple question, if I use the "at" command to set a job at a particular time, and the system for some reason is down at that time, when it comes back online, does it immediately run the jobs that were scheduled during the downtime?

I think it probably would, but just asking to make sure

Thanks in advance for your helpful responses.

A simple question with a complex answer sorry

It depends on the implementation of at.

Most of the 'standard' at's around will not run the job ever if the system is down for the precise second it was meant to run.
In this case, you can either change to a different version of at or add some smarts to your script and have it run more often.

For most distributions of linux though, at (and cron) behave differently and can generally be counted on to run anything 'missed' when the server was down.

Short version: Probably. Best you try it out
