how would i make a bash script that would ask me a y/n question

i need to run a program at start but i want it to ask me wether or not i want to

This is one way of doing it:

Code:

#!/bin/bash

VALID=no

while [[ $VALID = no ]]
do

  echo -n "Do you want program X to run? (YyNn) : "
  VALID=yes
  read ANSWER

  case $ANSWER in
    Y|y ) echo "Answer is : $ANSWER" ;;
    N|n ) echo "Answer is : $ANSWER" ;;
      * ) echo "Invalid reply."
          VALID=no ;;
  esac

done

It includes an 'error' check, only Y, y, N and n are valid.
I'ts not finished, but I guess you can take it from here.

Hope this helps.

If you don't want the switch statements try this:

Code:

#!/bin/bash
echo -n "Do you want to run the program? : "
read ANSWER

if [ "$ANSWER" = "yes" ]; then
	....run this code....
else
	exit 0

If you type 'yes' it will start, anything else will end the script
