Shell Programming and Scripting

Hello There!

What i'm trying to accomplish is...

(1) Anytime i monitor the logs, the logs generated at that minute will be redirected to a temporary file(error).

Code:

more wl-domain.log | grep `date +%H:%M:` >> $error

(2) And i'm checking the word count of the file, assuming that increase in the count more than 22 had logged the grepped string.

Code:

a=`cat errorfound.txt | wc -l`

(3) If logged so, i should get an alert.

(4) By default the file has 22 lines, So if anything apart from that gets logged the count increased obviously... So, i used a comparision here to make the difference to get an alert.

Code:

if [ $a -gt $b ]
then
cat /opt/app/bea/wli81sp6/user_projects/domains/tsliptDomain/bhargavk/errorfound.txt | mailx -s "Alert!!!" $TO
fi

Now the issue is, even if the particular parrern is not generated, i'm getting alert.

Hi,

I got the resolution for this. Thanks to 'Chris F.A. Johnson'. From one of his post i come to know about the new opperend 'newer' and with help of that i've compared the newer file.
