How to return a string?
Code:
function blah {
return "string"
}

it keeps saying string: not found

How can i do this guys? Because I'm trying to do something like this

Code:
function print_daemon_options {
	echo "Start Daemons - Please enter one or a combination of the following:"
	
	if isDatasubEnabled && isReconEnabled; then
		echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
		allowedInput = "1 2 3 4 5 6 7"
	
	elif isDatasubEnabled && isReconEnabled=0; then
		echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
		allowedInput = "1 2 3 4 6 7"

	elif isDatasubEnabled=0 && isReconEnabled; then
		echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
		allowedInput = "1 3 4 5 6 7"
		
	else
		echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
		allowedInput = "1 3 4 6 7"
	fi
	
	return $allowedInput
}

Try:
Code:
function blah {
  echo "string"
}

Functions return numbers (return codes).

echo the string, or set it in a variable.

i.e.
Code:
blah() {
  _RC="string"
}

blah
echo $_RC

Code:
blah() {
  echo string
}

_RC=$(blah)

Thanks for the reply Scott. I've got a function like this

Code:
function print_daemon_options {
    echo "Start Daemons - Please enter one or a combination of the following:"
    
    if isDatasubEnabled && isReconEnabled; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput = "1 2 3 4 5 6 7"
    
    elif isDatasubEnabled && isReconEnabled=0; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput = "1 2 3 4 6 7"

    elif isDatasubEnabled=0 && isReconEnabled; then
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput = "1 3 4 5 6 7"
        
    else
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput = "1 3 4 6 7"
    fi
    
    echo allowedInput
}


function stop_daemons {
    print_daemon_options

    echo $allowedInput
}

stop_daemons calls the print one which should echo the options and also return the string but the error I get is:

Start Daemons - Please enter one or a combination of the following:
1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit
print_daemon_options: ./wmfo_menu.sh[383]: allowedInput: not found
allowedInput

You need to remove the spaces from your variable assignments:

Code:
allowedInput="......"

I presume all of the isDatasubEnabled etc., are external programs?

I made the change and I still get an error (and also, yep isDatasubEnabled and isReconEnabled are functions within the same script)

Code:
function print_daemon_options {
    echo "Start Daemons - Please enter one or a combination of the following:"
    
    if isDatasubEnabled && isReconEnabled; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput="1 2 3 4 5 6 7"
    
    elif isDatasubEnabled && isReconEnabled=0; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput="1 2 3 4 6 7"

    elif isDatasubEnabled=0 && isReconEnabled; then
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput="1 3 4 5 6 7"
        
    else
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput="1 3 4 6 7"
    fi
    
    echo $allowedInput
}


function stop_daemons {
    print_daemon_options

    echo $(allowedInput)
}

Start Daemons - Please enter one or a combination of the following:
1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit
1 2 3 4 5 6 7
stop_daemons: ./wmfo_menu.sh[383]: allowedInput: not found

If this is the culprit
Code:
function stop_daemons {
    print_daemon_options

    echo $(allowedInput)
}
# then change to echo ${allowedInput}
