What can be done to save a script from failing, when it happens for a IF command to check a Null value with a value?

Can you please rephrase you question? Is your script failing when the If condition checks a null value?

I'm not at all sure I understand your question either, but I'll take a quick stab at it. Do you mean that you need to test for a null value to make sure your script will not fail? For example, if $j is a null string your script might fail?

export j=""
if [ "$j" = "" ]; then
    echo "null"
else
    echo "NOT null"
fi
 

Where you probably should choose to do something substantive instead of just "echo". :)

If this is not what you are asking, please try again.
