Module $4$: awk

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

$1.$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.
