Shell Script: Sorting by column using grep/awk
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:
You will write a script that will read a tab-separated file that contains the names of all 50 states & Washington DC, their populations, their land areas and their population densities, which is used to order the current list. The script will ask the user if they would like to have a new file sorted alphabetically by state name, by land area or by population. If they select by name or population, the file will output the state name, then the population, then the land area. If they select by land area, the file will output the state name, then the land area, then the population. The script will save the new file either as “states_alpha.txt”, “states_land.txt” or “states_pop.txt”, depending on the choice selected by the user.



2. Relevant commands, code, scripts, algorithms:
grep, awk


3. The attempts at a solution (include all code and scripts):
echo "How would you like the fifty_states.txt file to be sorted?
1 ) Alphabetically
2 ) By Land Area
3 ) By Population
Enter your choice: " choice

if $choice=1
grep '^[A-Z]' fifty_states.txt | awk '{ print $1, $2, $3 }' fifty_states.txt > states_alpha.txt

This does not work...I am not sure where to go from here.


4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
Jackson Community College, Jackson MI, USA, M. Brinkman, CIS106


Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).
