Then it would also output the second word of the header lines which you'd need to filter:awk '{if (NF > 1) print $2}' <file name> | egrep -v '[^-0-9.]'
You (almost) never need to pipe awk's output through (e)grep: awk 'NF == 2 && $2 ~ /^[0-9]+\.[0-9]+$/ {print $2}' FILE -- Kevin Rodgers Denver, Colorado, USA
