Absolute value in awk doesn't work?

Question

I want to select line of a file where the absolute value of column 9 is less than 500. Column is sometimes positive, sometimes negative.

awk -F\'\\t\' \'{ if         


        

Answer 1

Is this too obvious and/or not elegant ?

awk -F'\t' '$9 < 500 && $9 > -500' > output.bam
