I was trying to use the 'at' command.
Does it not have "resolution" to the second?
When I run it with 'at -f /tmp/tt.sh "01/21/2013 15:20:45" syntax error. Last token seen: 15:20 Garbled time
How do I run a command in the future including "seconds".
@Jerry: You might explain what it is you are attempting to do or why it is you need to schedule a job down to the second.
Thanks,
Jerry
I think you're limited to 1 minute granularity. But if you want to run something
Yes, both cron and at can be scheduled down to the minute (but no further). And for most jobs/situations, running every minute or every couple of minutes is suitable.
at a specific second (ie: 13 seconds after the minute), you could modify the script to sleep for 13 seconds before running and run it on the minute, or prepend a sleep in the cron entry itself:
- sleep 13; touch /tmp/foo
@Joseph: Nifty trick/hack! ;)
