I've seen some installation scripts and other such scripts ask for user input (IE: Do you wish to continue? ) but I can't find an example when I now need it. How can I read user input to a variable in bash?

'Do you wish to continue?'

A yes would continue, no would exit. Anyone?

Why not make it a function :)

#!/bin/bash
echo would you like to continue?
read continue
if [ $continue == yes ]; then
echo "You want to continue..";
else
echo "You dont want to continue..";
fi

Be sure to put a space between if and [, and a space between the brackets and the words/variables
It will show:

justin@justin-laptop:~/Desktop$ ./if
would you like to continue?
yes
You want to continue..
justin@justin-laptop:~/Desktop$ ./if
would you like to continue?
no
You dont want to continue..
justin@justin-laptop:~/Desktop$

Also you can pass arguments to your script like this.

#!/bin/sh

echo "The first argument is $1"

echo "The second argument is $2"

sh script.sh argument_one argument_two

One trick of those installation scripts is not need press enter or letting it be yes:

read -s -n1 -p "Do you wish continue?Y/n " key

case $key in

"Y" | "y") # continue ;;

"N" | "n") #quit;;

*) #continue;;
