Hi all,

I am tring to write a script which should read the first line of the file and perform some task. Once the task is completed the next line of the file should be read the task should be performed.
So is it possible to have a counter sort of thing, in sed or awk, which would increment and hence cause the next line to be read?
Following is how I thought of doing it, but it does not work as I can't assign value to $C to get to read a line:

C=1 #counter
while true
do
 LOG=`sed '$C!d' /var/log/somelog.log`
 #
 perform the task on $LOG
 #
 C=`expr $C + 1`
done
