Error: Your “crontab” on unexpected end of line. This entry has been ignored

Everytime you edit your crontabe file, the error “Your “crontab” on <server> unexpected end of line. This entry has been ignored” is sent to the users email. This happens if there is a blank line in your crontab file.

For instance, in the following crontab file there is a blank line between the last two cron jobs.

root@sunsolaris# crontab -l
# The root crontab should be used to perform accounting data collection.
#
# The rtc command is run to adjust the real time clock if and when
# daylight savings time changes.
#
10 1 * * 0,4 /etc/cron.d/logchecker
10 2 * * 0  /usr/lib/newsyslog
15 3 * * 0 /usr/lib/fs/nfs/nfsfind

30 4 * * * /usr/local/bin/disk_check,sh
;;;;
;;;
;;
;

To resolve the problem edit the crontab file and look for the blank line and delete the line. In the above, after editing the crontab, it should look lie the follows:

root@sunsolaris# crontab -l
# The root crontab should be used to perform accounting data collection.
#
# The rtc command is run to adjust the real time clock if and when
# daylight savings time changes.
#
10 1 * * 0,4 /etc/cron.d/logchecker
10 2 * * 0  /usr/lib/newsyslog
15 3 * * 0 /usr/lib/fs/nfs/nfsfind
30 4 * * * /usr/local/bin/disk_check,sh
;;;
;;
;

You can see the  blank line removed from the crontab file.
