AWK: is there some flag to ignore comments?
- by HH
Comment rows are counted in the NR.
Is there some flag to ignore comments?
How can you limit the range in AWK, not like piping | sed -e '1d', to ignore comment rows?
Example
$ awk '{sum+=$3} END {avg=sum/NR} END {print avg}' coriolis_data
0.885491 // WRONG divided by 11, should be by 10
$ cat coriolis_data
#d-err-t-err-d2-err

.115 0.005 0.9687 0.0001 0.595 0.005
