how do i create a shell script with multiple choice menu variables?
Here is what I am trying to do
Please pick from the following
1) area1
2) area2
3) area3
Now pick a place based on the area you chose
1) place1
2) place2
3) place3
Based on $area and $place here is what you need...
My guess is i need a combination of case and if statements but i am unable to wrap my head around the problem.
Use the select statement as @Barmar suggested.
Based on your example:
echo 'Please pick from the following'
select area in area1 area2 area3
do
case $area in
area1|area2|area3)
break
;;
*)
echo "Invalid area"
;;
esac
done
echo 'Now pick a place based on the area you chose'
select place in place1 place2 place3
do
case $place in
place1|place2|place3)
break
;;
*)
echo "Invalid place"
;;
esac
done
echo "Based on $area and $place here is what you need..."
I used a|b|c) to group multiple options, but you could provide separate code paths for each one. *) can be used as an "else" clause. Use break to break out of the menu loop. Use ;; between clauses in the case statement and ; between statements in a single clause.
