read -p "How would you like the file to be sorted?
1) Alphabetically by name
2) By Land Area
3) By Population
Enter number choice here: " choice
read choice

if choice
then
awk '{ print $2, $3, $4 }' fifty_states.txt > states_alpha.txt
sort states_alpha.txt
fi

if choice
then
awk '{ print $2, $3, $4 }' fifty_states.txt > states_land.txt
sort -k +1 states_land.txt
fi

if choice
then
awk '{ print $2, $4, $3 }' fifty_states.txt > states_pop.txt
sort -k +1 states_pop.txt
fi
We are not going to do your homework for you.
I suggest again that you look at the man page for the test command so you can craft your if statements to look something like:
Code:
if test "$choice" some condition check

or
Code:
if [ "$choice" some condition check ]

srtconfig

SRTCONFIG(1)						    BSD General Commands Manual 					      SRTCONFIG(1)

NAME

     srtconfig -- configure srt interfaces

SYNOPSIS

     srtconfig srtX
     srtconfig srtX N
     srtconfig srtX del N
     srtconfig srtX add srcaddr mask dstif dstaddr
     srtconfig srtX set N srcaddr mask dstif dstaddr

DESCRIPTION

     srtconfig configures, or queries the configuration of, srt(4) interfaces.	An srt(4) interface parcels packets out to other interfaces based
     on their source addresses (the normal routing mechanisms handle routing decisions based on destination addresses).  An interface may have any
     number of routing choices; they are examined in order until one matching the packet is found.  The packet is sent to the corresponding inter-
     face.  (Any interface, even another srt interface, may be specified; if the configurations collaborate to cause a packet to loop forever, the
     system will lock up or crash.)

     When run with only one argument, srtconfig prints the settings for the specified interface.

     When run with two arguments, srtconfig prints the settings for the routing choice whose number is given as the second argument.

     The form with 'del' deletes a routing choice, identified by its number.  Other choices with higher numbers, if any, will be renumbered
     accordingly.

     The 'add' form adds a choice; the other arguments describe it, and are documented below.  The new choice is added at the end of the list.

     The 'set' form replaces an existing choice, given its number.  The other arguments describe the new choice which is to replace whatever cur-
     rently exists at the given number N.

     A choice is described by four pieces of information: a source address and mask, which are used to determine which choice an outgoing packet
     uses, a destination interface, and a destination address for the new interface.  The source address and mask are specified like any Internet
     addresses (for convenience, the mask may instead be specified as a '/' followed by a small integer, CIDR-style; note that in this case the
     mask must still be a separate argument; it cannot be appended to the end of the source address argument).

     Each srt interface also has ordinary source and destination addresses which are set with ifconfig(8) like any other interface; these should
     not be confused with any of the above.
