As mentioned in another thread, if you tell us what operating system you're using, what shell you're using, what you're really trying to do (instead of how you want it done), and show us what you have tried and explained what about it is not working; we would have a MUCH better chance of helping you reach your goal.

If you goal is just to skip processing the first line from a file you're reading from standard input in a script, the simple answer is to change:

Code:

while read line
do	whatever
done

to:

Code:

read line
while read line
do	whatever
done

Please help us help you by telling us what operating system you're using, what shell you're using, giving us a complete description of what you're trying to do, giving us a short sample input file and showing the exact output you hope to produce from that input, and showing us what you have tried to do to solve the problem on your own.
