# Basic syntax:
case "STRING" in
	patterns)
		echo "commands to perform if patterns matched STRING"  
        ;;
	to)
        echo "commands to perform if to matched STRING" 
        ;;
    search)
        echo "commands to perform if search matched STRING" 
        ;;
    *)
        echo "anything that wasn't matched by the previous patterns"
        exit 1

# Example usage:
# If you want to write a bash script where you ask the user how to proceed, you
#	could do something like this:
read -r -p $'\nDo you want to perform this action? (y/n/q): ' RESPONSE
	case $RESPONSE in
    	[Yy]*)
        	echo "The user chose y"
        	;;
        [Nn]*)
        	echo "The user chose n"
            ;;
        [Qq]*)
        	echo "The user chose q, script aborted"
            exit 0
            ;;
        *)
        	echo "The user chose something other than y, n, or q"
            ;;
	esac
# Note, the patterns like [Yy]* will match the string in $RESPONSE if that
#	string starts with Y or y followed by any number of other characters. So
#	it would also match Yes, yes, yertyujiwjwijdwi, etc
# Note, if you want this message to keep repeating until the user types q, put
#	the above in a while loop that never ends (e.g. while true; do ... done)
