Enable cron log in Ubuntu 10.04 (Lucid Lynx)
By default, the output from cron goes into the default general system log "/var/log/syslog" in Ubuntu.
If you prefer to have an unique file for cron log, you can edit the file "/etc/rsyslog.d/50-default.conf"
Uncomment the line (Remove the #):
And finally restart the log service
# service rsyslog restart
