in case someone needs to do something similar in the future.

Glad you got sorted.

You'll find that many admins (myself included) would have used a script rather than modify the cron job, so you'd end up with:

/root/getsmart.sh

Code:

#!/bin/bash

# Author : TenTenths
# Purpose: Dump drive smartctl data to log file
# Version: 1.0
# Date   : 5th Oct 2016

# Version History
# 1.0 Initial version

# Set your options and log file as appropriate
LOGFILE="/home/michaelzheludev/CRON/smartctl-output-$(/bin/date +%d%m%y)"
OPTIONS="-aixcA -d sat /dev/sda"

# Script logic starts here
/usr/sbin/smartctl ${OPTIONS} >> ${LOGFILE}

# Elvis Has Left The Server

Then your cron can just be:

Code:

00 11 * * * /root/getsmart.sh

+1, i also like:

Code:

date +%Y-%j
