How can I automatically restart my node js server every 4 hours automatically. There is a bug that only shows up after 4 hours and I want to be able to run it through the night.
I'm already using forever.
Thanks,
Arjun
It doesn't sound like you're really solving the problem... But you could use a crob job.
Something like:
0 */4 * * * forever restart <MYSCRIPT.JS>

What would be the cron expression for "nth second of every minute"?
For example, for every 5th second of every minute, the cron would run at 1:00:05, 1:01:05, 1:02:05 and so on.. 24x7.
I could not find any documentation for achieving this.
Thanks in advance!
This functionality is not available out of the box. What you could do is prepend your command with sleep, so it would be:
sleep 5 && /app/script.sh
Figured it out. The cron expression would be.
5 * 0 ? * *

I don't have a box to test a cron job so I am posting it here.
I want to run a job every hour between 6 am to 18:00.This is what I have tried
0 6-18/1 * * * <command>
and
0 6-18 * * * <command>
Which one is the correct way of achieving it
Both should work, but I would probably use the second one.

I want to use the command "at" to schedule a job to run at one second (or minute/hour) later. If using "-t" option, then it involves with the hassle of getting the current time etc. Is there any easy way out?
But don't suggest me to use "sleep", because the current process will exit.
Thanks for the tip.
The at program can take now+ a time unit (e.g. now+1minute) as a timespec. You won't get finer time resolution than one minute with at.
