Hosting with second cron?

Question

Task Schedulers

What site hosts do you know that can set cron jobs every few seconds?

Answer 1

cron itself does not support running every few seconds. Only programmatically modify, already inside the script

Answer 2

organize a queue of tasks and execute them with a regular cron, but with the script running time ~= the time between two cron runs.

Answer 3

Put in rc.local
while true; do echo "run every second" > /dev/null 2>&1 && sleep 1s; done
