  1. I want to extract only lines with "ADD" in col. 5 (TEST).
  2. I want to sort ascending on Col 9 (P). This column as shown above has both regular and scientific formats.
  3. How can I keep the headers of the file intact in the outfile?
What I tried:

Code:
gawk '{if(NR>1 && $5="ADD") {print $0}}' infile>outfile

Everything in col5 is changed to ADD.
