HELP!!!

LINUX/UNIX: Awk/SED Commands and Programs. Solutions, please. Thanks!

Here is what is inside the cars file. It has 6 fields (Make, Model, Year, Mileage, Features)

1. Write a command to show only the make, model, and year of the listed cars.

2. Write a command to show make, model, year, and price (in that order) of all the cars, sorted by price from lowest to highest.

3. Write a command to show the make, model, and mileage, and price of all the cars that have a less than 40,000 miles on them.

4. Write a command to display a list of all the car models. Each model should appear only once.

5. Write a gawk program that uses the cars file, displays all cars priced at more than $5,000, and sends its output to standard output.
