Question

How can I get all differences, not just one? I want to use the calculated result for each item in the third column. The dilemma is that if I remove END I can print $3 but cannot have ave. If I leave END I have ave but not all differences.

awk '{sum+=$3} END {ave=sum/NR} END {print $3-ave}' coriolis_data
-0.00964   // I want to see the rest differences, how?

coriolis_data

.105    0.005   0.9766  0.0001  0.595   0.005
.095    0.005   0.9963  0.0001  0.595   0.005
.115    0.005   0.9687  0.0001  0.595   0.005
.105    0.005   0.9693  0.0001  0.595   0.005

Answer 1

then you create another array to store $3 values. And use only 1 END block

awk '{sum+=$3;s3[NR]=$3} END {ave=sum/NR; for(i=1;i<=NR;i++)print s3[i]-ave}' coriolis_data
