Shell Programming and Scripting

hi all ,i would like a shell script that parses log files and checks the contents for any anonalities,please help,thanks

you're welcome.
If you could be more specific - you could get better help.

example :
create file with content :
"tail -n 20 /var/log/messages tail -n 10 /var/log/auth.log"
save as file, chmod 755 and call it : ./your-desired-name
It will output the contents of the log files located at the respective places. As "vgersh99" pointed out before me, please be more specific in your questions to narrow the suggestions.

hi there,thanks for your replies.

What i meant to say was I need a shell script that look through the contents of multiple logfiles to locate anomolies, system attacks and faults.

Furthermore to be able to report via email the list of entries that do not match list of acceptable log entries.

Im more interested in the first part but if u can also do the second part,Your help would be highly appreciated.
Thanks.

I'm posting my example with changed credentials, feel free to replace any values ; or use the logic : ( it's very simple )

Code:

#!/bin/sh
echo " " > /home/user/blacklist
for i in 2 3 4 5 6 7 8 9 10 
do
myVarScript -parameter www$i.domain.com >> /home/user/blacklist
sleep 10
done
line=`cat /home/user/blacklist |grep BLOCKED | wc -l`
echo $line
if [ $line -eq 0 ]
then
echo " "|mail -s "That's the subject" hostmaster@domain.com
else
cat blacklist | grep BLOCKED | mail -s "Did not match the pattern" hostmaster@domain.com
fi
exit 0
