Hi,

I trying to test two condition together (AND) under bash but it's not working...

The goal is ti have True when two variables are either not set or empty (empty string)

I've tried

if [[ -n VARIABLE1 && -n VARIABLE2 ]]; then
    echo "OK"
fi

Here I get the "OK" no matter what .

Thanks.

Try this:

#!/usr/bin/env bash

a=""
if [[ -z "${a}" && -z "${b}" ]]; then
    echo "OK"
else
    echo "Not OK"
fi

a="OK"
if [[ -n "${a}" && -z "${b}" ]]; then
    echo "More ${a}"
else
    echo "More Unokay"
fi
