hi, actually,my need is like,in the given file i have to find the line which has the keyword "Not authenticated by System" and
"authenticated by System".and i have to get the corresponding names which here is 'sharmila' and 'shivu'.
If it is not authenticated i have to make the status as 'Failure' otherwise as 'Success'.
So here In case of 'Not authenticated i can read the name'sharmila' from the same line.But in case of 'authenticated' i have to trace back the line which has the same timestamp.it may be in anyline.here is my code.


for i in $(grep -n "authenticated by System" logfile.txt|cut -d: -f1)
do
sed -n "${i},${i}p" logfile.txt| /usr/xpg4/bin/grep -q "NOT authenticated by System"
if [ $? -eq 0 ]
then
sed -n "${i},${i}p" logfile.txt|cut -d" " -f5 | sed '1s/^.//' | sed '$s/.$//' >> msg.txt
echo "Failure" >> msg.txt

else
sed -n "${i},${i}p" logfile.txt| /usr/xpg4/bin/grep -q "getCredentials"
if [ $? -eq 0 ]
then
sed -n "${i},${i}p" logfile.txt|cut -d" " -f4 >> msg.txt
echo "Success" >> msg.txt
fi

fi
done


so my need is in the else part how i can get that particular mathched line.
As i am new to unix ,i dont know how i can do this using awk.
Can anyone tell me ,whether in the given code i can get that line or how i can apply the awk here.


logfile:
--------
[22/Jul/2008:19:35:45-20401-23-1] getCredentials - sharmila
[22/Jul/2008:19:35:45-20401-23-2] DoLogin - Setting variables
