[LUG] AWK multipass
Today I thought I would learn awk programming so that I could scale a
list of numbers. It seems that awk only does one pass of a file. I need
two passes, the first which simply adds all the numbers, the second
which divides each number by the sum.
Any suggestions?
The file that I need to convert has one number per line, eg.
2.3e-7
4.2e-8
4.7e-8
Should convert to:
0.721
0.132
0.147
Thanks
Andrew
