Firstly. There is never ever a reason to use "for" when dealing with an open-ended list.
Secondly. Convoluted one-liners should be formatted scripts.

Quote:
for messages in `cat syslog_message_list.txt`; do grep $messages syslog.`date +%d%m%y`.log | tr -s " " | cut -d" " -f4,9- | sort| uniq -c >> syslog.`date +%d%m%y`.report; done

This "while" construct easier to read when properly laid out and does not include the risk of a "for" line becoming too long or not dealing with space characters correctly:

Code:
cat syslog_message_list.txt | while read messages
do
       grep "${messages}" syslog.`date +%d%m%y`.log | \
       tr -s " " | \
       cut -d" " -f4,9- | \
       sort| \
       uniq -c >> syslog.`date +%d%m%y`.report
done

Thirdly. Don't run convoluted on-liners from cron. Run a script containing appropriate environment settings - especially the Shell shebang and of course a correct $PATH which includes a path to Pearl.

syslog

SYSLOG(8)                                                         System Logging                                                         SYSLOG(8)

NAME

       syslog-ng, syslogd

DESCRIPTION

       There are different syslog daemon implementations supported as the system's syslog service, currently syslogd, syslog-ng and rsyslogd

       The  first  installed daemon activates itself for the syslog service. Starting with openSUSE-11.2, it is rsyslogd, before it was syslog-ng.
       But this depends on the software selection during the installation.

       The name of the daemon used as syslog service is specified in the
       SYSLOG_DAEMON variable in /etc/sysconfig/syslog.

       The yast2 sysconfig module provides a comfortable way to switch to another installed daemon and restart the service.

       The /etc/init.d/syslog init script is able to handle all supported daemons.
