Linux, code that checks there are no currently running cron jobs?

Question

How would I write a bash script that checks there are no currently running cron jobs, then does some simple action?

I am not talking about cron jobs that are scheduled to run at some point, I am referring to actively running processes.

Thanks!

Answer 1

intresting question ;)

for pid in `pgrep cron`;do
  ps uh --ppid $pid;
done|grep -v CRON

Answer 2

You can read the crontab like this

crontab -l | grep -v "^#" | awk '{print $6}'

and check if any of the script/job is running
