awk -F"\t" '{ print $2, $3, $4 }' fifty_states.txt | sort > states_alpha.txt
fi

Note that I added code tags...

I don't see why states_alpha.txt would not be created by this command (assuming that you just entered 1 and a carriage-return after the prompt printed by echo). But I don't see why you are discarding the state's name (the 1st field in your input file) from the data you are feeding into sort.

Try adding:
Code:
set -xv

as a new line before the echo in your script so you can see how your shell is expanding the variables it is processing.
