1 What is the function of the /etc/crontab file in Linux?

-to schedule system jobs
- to schedule user jobs
-to validate created processes
-to remove cron jobs



Im thinking this:
-to schedule system jobs
but im not 100% sure

Answer 1

You're right, it is for system jobs.

You may be thinking it could be to schedule user jobs, but if you look at the format of the file, there is no place for a user, or uid.
