Module 3: sed All steps should be done using one command line and the sed utility. Don't use any other filter such as cut, grep, etc. Copy the file lab3in from the cis18b directory to your current directory. The file lab3in has a header line and an ending line of text. In between are lines about the 6 continents, where each line has 3 fields, with ; as the delimiter. Use this file for all steps below. To compare sed with previous filters that you know (and as a review of these filters): 1. Write a sed command line that has the same output as: head 4 lab3in | tail 2 2. Without using line numbers, write a sed command line that has the same output as: grep 'America' lab3in 3. Without using line numbers, write a sed command line that has the same output as: wc 1
