In the Linux world we all love using Cron for lot’s of different background / scheduled tasks, since Cron jobs are not in foreground it’s really hard to debug them.
The easiest way is simply to send all STDOUT and STDERR to Syslog
* * * * * echo "test message" 2>&1 |logger
If you want to debug your bash script just add debug mode to the beginning of your script
To ensure your jobs are executed tail on /var/log/cron
tail -f /var/log/cron
To see all the outputs in Syslog
tail -f /var/log/messages
