Script to check for certain error message in logs

[Hunki]

I have to check for an error message : "many connections" in a log file on the system.And if that error occurs then mail me immediately. How can I achieve this.

grep "many connections" /home/jb/log/ser.log

thanks,

hunki

Hi Hunki:

# grep -q "many connections" /home/jb/log/ser.log && mailx -s "Alert!!!" root < /dev/null

See the manpages for more information. This is a "quiet" grep. If the return code is zero (one or matches found), then a mail is generated.

Regards!

Shalom Hunki,

I've posted scripts like that very often.

grep "error message" /var/adm/syslog/syslog.log

You can do a count

number=(grep "error message" /var/adm/syslog/syslog.log | wc =l)

echo $number
