⟩ What is crondtab daemon?

The cron daemon reads the /etc/cronlog.conf configuration

file provided by the user to log the information. If a

configuration file has not been created, then the cron

daemon creates a log of its activities in the

/var/adm/cron/log file. The cron daemon reads the

configuration file when it is activated and when it receives

the hangup signal.

If the cron daemon is not able to create or open the

user-specified logfile, then it creates a log of its

activities in the /var/adm/cron/log file.
