RE: [CentOS] Linux at command

I'm having a problem with the Linux (unix) at command. I have a program/script that needs to run another program/script within seconds. Unfortunately the at command only accepts minutes as input. Therefore, scheduling a command within a minute (i.e. adding 1 minute to the current time), can cause the command to run within 1 to 60 seconds. (Add 1 minute to a time such as 11:43:59 will cause it to run at 11:44:00, one second later.) I don't quite understand why unix has this limitation. Is there something else I should be considering?

You might want to fire the second script from the first with whatever delay you deem appropriate and only use at to launch the first script.
