All steps should be done using one command line and the awk utility. Don't use any other filter such as cut, grep, etc.

Comparing awk with sed by doing the same first $6$ steps but using awk:

$1.$ Write an awk command line that has the same output as: head $-4$ lab$3$in $|$ tail $-2$

$2.$ Without using line numbers, write an awk command line that has the same output as: grep $$America$$ lab$3$in

$3.$ Without using line numbers, write an awk command line that has the same output as: wc $$l $<$ lab$3$in

$4.$ Without using line numbers, write an awk command line that has the same output as: grep $-$v $\text{'}^$$$\text{'}$ lab$3$in

$5.$ Without using line numbers, print only the lines with continent data, indenting each line by $3$ spaces.

$6.$ Without using line numbers, print the continent names and areas, separated by colon $($:$).$Only the continent names and their areas should be printed.
