If or Case Statement

Ernst · #1 (**permalink**) 09-24-2008

I want to write a program with the following variables:
a=7000
b=24000
c=613.8
The user can enter two words: Vivid or Blue for example. The challenge is that the user might not want to write the words the way they appear. The user can write V or v or vivid or Vivid or write Blue or blue, or B, or b

What I want to do is to ask the user which word he/she wants to write. If the user enters any of the four choices for vivid, I want the program to do a / c. If the user decides to write any of the four choices for Blue, the program should do b / c.

Who can help with that?

Thanks!

Code:

#!/bin/ksh
a=7000
b=24000
c=613.8

echo "Please enter vivid or blue \c"
read ans
echo "$ans" | tr -s '[:upper:]' [:lower:]' | read answer
case $answer in

     b*)  printf "%f\n", $( echo " $b / $c " | bc -l) ;;
     v*)  printf "%f\n", $( echo " $a / $c " | bc -l) ;;
     *)   echo "invalid response" ;;
       
esac

This is a start
