Ok...we'll be glad to HELP. That means, you write the script, and post it, telling us where you're getting stuck. But we're not going to write scripts for you.

There are many bash scripting tutorials you can find via Google. You can also read the man pages for "head" and "tail", both of which can be used here to quick-and-dirty a script to do what you want.

And by the way, it's spelled "lines".

An even bigger hint: Look at the addressing functionality in SED. Really good SED tutorial here:
