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.

      Never use a && b || c. It is not the same as if a; then b; else c; fi: when a succeeds but b fails, it will run both b and c.

      I would not bother with [ unless you absolutely need compatibility with non-bash shells.
