Add another condition to bash for when not met
In the below I can not seem to add a line that will add Not low if the statement in bold is not true or meet. I guess when the first if statement is true/meet then print low, otherwise print Not low in $(NF + 1). I am not sure how to correctly add this. Thank you Smilie.

Code:
if(low[i] <= $2 && $2 <= high[i]) {
            # Match found, add field and break out of loop.
            $(NF + 1) = "low"
            Else
[I]if(low[i] != $2 && $2 != high) {
            # No match found, add field and break out of loop.
            $(NF+1) = "no low"
            fi
            break

The portion in italics was an attempt to do this, but only the first if seems to work.

The desired output would be tab-delimited, but that is already part of the complete code:

Code:
line1     Not low
line2     Not low
line3     Low
line4     Not low
