SUMMARY: Clarification: Script question

Thanks for the excellent answers!

The suggested methods were:

awk '(NR==linenumber){print};{next}' file
sed -n '<line>p' file
tail +line# | head -1

I'm using the awk suggestion.

Thanks for replies from Jesse Rhoads, Joseph Bueno, Bertrand Hutin, Brett Geer, Bob Vickers, Dragi Raos, Randy Schrickel, and Jason Dixon.
