How Do I Use 'AT' or Cron?


How can I run a scheduled job in a specific hour minute second (hh:mm:ss)
I tried “at” but I do not know how to send it “seconds”.
Any idea?

You can't send AT seconds, and you can't send cron seconds either.

I don't believe the default versions of at or cron support seconds.

Thank you for the answer,

And then is the any other command that I can use to run a command after h hours, m minutes and s seconds?

Why the need for seconds? It seems to be a strange approach.

You could conceivable write a wrapper shell script with a "sleep X" and
then whatever you want to run at the second ... but that may bear a little
inaccuracy given the non-real-time time slicing in the ordinary Linux
kernel ... what makes the requirement of a second necessary?


Cheers,
Tink
