I need help really quick, this is due in an hour. Here is my new code, I just need to figure out how to get the user input to do the correct command, which is why I left the "if choice" blank...or should it be "if $choice" ?
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

x2sys_merge
X2SYS_MERGE(1gmt) Generic Mapping Tools X2SYS_MERGE(1gmt)
NAME
x2sys_merge - Merge an updated COEs tables
SYNOPSIS
x2sys_merge -Amain_COElist.d -Mnew_COElist.d
DESCRIPTION
x2sys_merge will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second
file should only contain updated COEs relatively to the first one. That is, it MUST NOT contain any new two tracks intersections (This
point is NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had
to recompute only the COEs between the edited files and the rest of the database.
-A Specify the file main_COElist.d with the main crossover error data base.
-M Specify the file new_COElist.d with the newly computed crossover error data base.
OPTIONS
No space between the option flag and the associated arguments.
EXAMPLES
To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try
x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt
