Alert log monitoring problem

Question

Hi guys!
I have found good simple script for alert log monitoring BUT it doesnt shows date and time. How to format it so that i could see date and time as well in log output?
+#!/bin/sh+
+#GLOBS+
ALERT="ORA-";
LOGFILE=/path/to/my/alert_X.log
MYFILE=/home/user/test.log
+##+
+#get the errors out of the logfile.+
grep -h "$ALERT" $LOGFILE >> $MYFILE
+#count number of lines in myfile, and print.+
+VAR=`wc -l $MYFILE | awk -F" " '{print $1}'`+
+#echo $VAR+
+# if the amount of lines is greater than 0, then cat the file and send it to me. if not then echo all clear.+
+#size variable is the number of errors the last time the script ran+
+size=`wc -l test.last | awk -F" " '{print $1}'`+
echo $size
+# if the amount of lines is greater than 0, then cat the file and send it to me. if not then echo all clear+
+if [[ $VAR -gt $size ]] ; then+
cat $MYFILE | mail -vs "oralert" [email protected] ;
else
echo "All clear.."
fi;
rm test.last
mv test.log test.last
touch test.log

The alert_log is know to first put the date of the message into it, and then on the next line the ORA- error message.
So in the case you would find an ORA-error here, then what is the problem into going into the file and start looking at what time it occured.
Otherwise you would have to modify the script in such way that it will get more info than a 'grep' at the moment it finds the error, like using "grep -l" option, that simply matches the lines.
Then a while loop in the script could "walk" trough these lines and get the surrounding lines around that line number from the alert_log.
But, again, if an error pops up, you do want to go into the alert-file, looking up all given info e.g. about the object(s) involved, the users, if a tracefile was generated...etc,etc,.
