What utility do I use for...
 

- Write a sed script that prints the 10 country names on lines 15 to 24, with 2 names per output line, separated by a semicolon. Also print a header line with the text: Lines 15 to 24.
- Use awk to produce the same output as: cut –d’,’ –f2 lab3in | tail -1
- Write a sed script that prints every 3 lines (1, 4, 7, 10…) between lines 1 and 20.
-Use sed to produce the same output as: cut –d’,’ –f2 lab3in | tail -1

Thank you!

It's called a search engine, cas this place ain't for doing your homework for you and this smells of homework. Alternatively, manpages.

We will be happy to assist with homework, if you show us what you've tried and what the results were. We just won't do it for you. See the LQ Rules, twelfth bullet item: http://www.linuxquestions.org/linux/rules.html

Just a thin disguise might be helpful.

What is your question?

I am with dugan seeing as your homework questions not only tell you what they want but what utility to use ... so what is YOUR question?
