Shell Programming and Scripting

Hi.
Is there any way of in a script ask the user something and with the user answer retreave a internal result that uses the variable that the user had introduced?

Thanks

Yes. You can use echo or printf to issue a prompt. You can use read to get a user response. (On some systems, read has an option to also issue a prompt before reading the user response.) Then you can use the variable(s) set by the read in whatever way your script wants to use them.

If you give us a little more detail about what you're trying to do, we might be able to provide a meaningful example.

Code:

echo "What do you want?"
read wants
case $wants in 
  bananas ) 
    echo "Yes we got no bananas 
  ;;
   "change" )
      echo "When do we want it?"
    ;;
esac

Bash supports this:

Code:

read -p "Gimme some value: "
echo $REPLY
