My system is centos 7.4.
After crontab -e,I add
MAILTO=root
30 4 * * * root /usr/sbin/aide --check
Then I receive email as below:
From: "(Cron Daemon)" <[email protected]>
To: [email protected]
Subject: Cron <root@myserver> root /usr/sbin/aide --check

/bin/sh: root: command not found
I checked /var/log/aide/aide.log is empty, there's no any information in messages and secure.It seemed my crontab script is somewhere wrong.
I just want to receive aide --check report,where is the problem?
The command you must exec is this:
MAILTO=root
30 4 * * * /usr/sbin/aide --check
Cron interpret root as command. The original cron records differ from those in cron.daily and so on directories because the standard cron records are per user, not per specific time
