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).

NAME

       populations - population genetic software

SYNOPSIS

       populations

       populations [name_of_input_file] [option]

       You can use populations as a command line programm (very useful for batch treatment) to infer phylogenetic trees.

DESCRIPTION

       populations is a population genetic software. It computes genetic distances between populations or individuals. It builds phylogenetic
       trees (NJ or UPGMA) with bootstrap values.

FEATURES

       o   haploids, diploids or polyploids genotypes (see input formats)

       o   structured populations (see input files structured populations

       o   No limit of populations, loci, alleles per loci (see input formats)

       o   Distances between individuals (15 different methods)

       o   Distances between populations (15 methods)

       o   Bootstraps on loci OR individuals

       o   Phylogenetic trees (individuals or populations), using Neighbor Joining or UPGMA (PHYLIP tree format)

       o   Allelic diversity

       o   Converts data files from Genepop to different formats (Genepop, Genetix, Msat, Populations...)

OPTIONS

       -phylogeny ind|pop
	   (default) for phylogenetic trees based on individuals or populations

       dist method
	   (default: Nei standard, Ds) you can choose among: DAS, Dm, Ds, Dc, Da, dmu2, Fst, Cp, Dr, ASD, Dsw, Dr, Dru, Drw, Drl. see distances
	   for details.

       -construct method
	   (default: upgma) possibilities upgma or nj (Neighbor Joining)

       -bootstrap_ind n
	   number to indicate the number of bootstraps to perform on individuals

       -bootstrap_locus n

	   number to indicate the number of bootstraps to perform on loci
		 .RE

	   -output name_of_treeview_file
	       to indicate the name of the tree file (phylip tree format)

	   -level n
	       number , structured populations allows to choose the structuration factor (in the example: town level is 1, building level is
	       2...).

EXAMPLE

       populations toutc2.txt -phylogeny pop -dist Dm -bootstrap_locus 10000 -output toutc2_10000_Dm.tre

       Commands can be write in a .bat file (for DOS) or a script file (for UNIX)
