A crontab is a service using which we can run task at
scheduled intervals.
Cron searches /var/spool/cron for crontab files which are
named after accounts in /etc/passwd; crontabs found are
loaded into memory. Cron also searches for /etc/crontab and
the files in the /etc/cron.d/ directory, which are in a
different format then wakes up every minute, examining all
stored crontabs,
Additionally, cron checks each minute to see if its spool
directory’s modtime (or the modtime on crontab) has
changed, and if it has, cron will then examine the modtime
on all crontabs and reload those which have changed.
/etc/cron.deny:
/etc/cron.daily/:
/etc/cron.hourly/:
/etc/cron.monthly/:
/etc/crontab:
/etc/cron.weekly/
